packs. Bigger packs will take longer to charge from empty. The
|
||||
capacity is on the cell label next to the yellow connector.</p>
|
||||
|
||||
<p>Each pack has a sliding indicator on the side. This is entirely
|
||||
manual, but is very useful for indicating when a pack is known to be
|
||||
charged, flat, or partly discharged. Slide the slider to show green
|
||||
for full, red for flat, half and half for 'partly used'.</p>
|

<h3>Using Makita charger</h3>
|

<li>Make sure charger is powered (flashing green LED).</li>
|
||||
|
||||
<li>Plug batt into Makita charger. It should start charging.</li>
|
||||
|
||||
<li>Look at the LEDs for status - the legend is printed on the charger.
|
||||
If it flashes 'broken battery' (flashing red and gren LED) at you
|
||||
after a few seconds, use the yellow (Pro-Peak Prodigy II) RC charger instead.</li>

<li>Eventually it should show '100%' (steady green LED) (in about 1
|
||||
hour max). You are done.</li>

<h3>Using Balance charger</h3>
|
||||
|
||||
<p>This is the set of 3 (2 half-width) chargers made from old Makita chargers. They have a set of 4 LEDs. (The full-width one only has 1 LED in 2018). Charges at 40W.</p>

<li>Look at the LEDs for status - the legend is printed on the RH end charger. Steady red for bulk charging to 80%. Steady orange for last 20% charging. Steady green for finished. If it flashes red and beeps (repeated 5 times) something is wrong - see table. If you get an 'undervoltage' reading, use an RC charger instead to get the charging started.</li>

<p>The Yellow Propeak chargers do the same job, and insturcuctions are

|
||||
|

<ol>
|
||||
<li>Make sure charger is powered (display lit up)</li>
|
||||
|

<li>Connect charger to battery (either hardboard adaptor or empty

|
||||
<li>If it shows '4' as the number of cells, then press 'start/enter'
|

again. Charging will start (fan comes on, display changes). If it
|

shows anything else like 'polarity reversed' or 'connection break'
|
||||
then fix the connection to the battery. If it shows '3' as number of
|
||||
cells it is probably knackered, but possibly can be coaxed back into
|
||||
action. Find a battery expert - don't just use the charger anyway.</li>
|
||||
|

<li>Once it beeps and says 'FULL' (flashing) then you are done (should
|
||||
be less than 2 hours). Display shows number of mAh put in in

|
||||
(between 50 and 2900 depending how discharged it was).</li>

</ol>
|

<h3>Can I tell if a battery is already charged?</h3>
|
||||
|
||||
<p>Simplest it try to charge it again and find that it says it is done
|
||||
in a couple of minutes (Up to 4 mins on the balance chargers). This
|
||||
may 'waste a life' on batteries that still work on the Makita
|
||||
charger. Checking it on the RC charger will not waste a life. It will
|
||||
quickly rise to 16.4V, and the current drop to 0.1A or so. That
|
||||
indicates a full pack. It will tell you so after a while (1-5
|
||||
mins).</p>
|
||||
|
||||
|
||||
<h3>What sort of batteries are they</h3>
|
||||
|
||||
<p>The drill batts are 4S2P 14.4V lithium ion packs (8 18650 cells: 4 in
|
||||
series, each being a parallel pair). This means that they are charged
|
||||
as 4-cell packs, to 4.1V per cell-pair. They can be charged at up to
|
||||
3A rate. Battery 1 has connector wired as balance connector. No other
|
||||
packs have this yet (2017). The official Makita packs use Sony SE
|
||||
US18650VT (1.5Ah, 20A high-drain) cells, and we have a few with with Samsung
|
||||
INR18650-13Q (1.3Ah high-drain cells). All give a reliable 2.3-2.6Ah
|
||||
capacity in practice, even after 9 years expo useage.</p>
|
||||
|
||||
<p>At end 2017 we bought two 4Ah packs. The non-makita one uses LG
|
||||
DAHD21865 cells (2Ah, 25A). I can't read the Makita cell type without
|
||||
unwelding the pack. For 2018 we made 3 new 5Ah packs from Samsung 25R
|
||||
cells (2.5Ah, 20A) (Sponsored by uk18650.com).</p>
|
||||
|
||||
<p>The drill discharges at 26A current draw when drilling (~400W), so
|
||||
that's 13A per cell in a 2P configuration.</p>
|
||||
|
||||
<h3>Makita charging protocol issues</h3>
|
||||
|
||||
<p>Makita have put very 'conservative' software in the batteries which
|
||||
will stop them working on the Makita charger, even when they are in
|
||||
fact fine. The monitoring board is powered off the 1st cell pair so
|
||||
that one tends to get discharged more than the others when left
|
||||
sitting for the 11 months of not-expo. If an unbalanced (or
|
||||
over-disharged, or too-hot) pack is inserted into the makita charger
|
||||
the charger and battery will do serial-coms negotiation, the charger
|
||||
will refuse to charge the battery and the battery will remember this.
|
||||
If you try this 3 times, the battery will mark itself bad and will
|
||||
never charge again on a makita charger. Only a replacement monitoring
|
||||
board can fix this (or new software if we knew how to nobble it).</p>
|
||||
|
||||
<p>Such batteries are normally still fine and charge on a sensible (RC
|
||||
- Radio Control, because RC people are the main market for these
|
||||
chargers) charger, possible after a balance charge to get the cells in
|
||||
the pack in sync again. Expo has a couple of these (Yellow Pro-power
|
||||
Prodigy II). Unfortunataly Makita don't build the 14.4V packs with
|
||||
balance connections to the cells, so the PCB has to be replaced to
|
||||
make this work easily for expo. For 2018 this was done for 7 of our
|
||||
packs, and 3 automatic balance chargers built.</p>
|
||||
|
||||
<p>Note that the drills have no battery-voltage monitoring at all, and the
|
||||
monitoring circuit is bypassed when conected to the drill (the charger
|
||||
uses a different connector-pair from the drill - that's why there are
|
||||
3 slots). Thus the drill can easily be used to over-discharge a
|
||||
battery, so please stop drilling when it gets slow and put on a new
|
||||
batt, unless it's an emergency. Drilling with an excessively-sagged
|
||||
voltage is a good way to knacker the weakest cell-pair. If your battery
|
||||
does get to this state, try to charge it up as soon as possible. Cells
|
||||
must not be left at <2V for any length of time as they rapidly
|
||||
(hours/days?) degrade to useless in this state (and that pair will
|
||||
need replacing).</p>

<h1>Makita Drill Battery Charging</h1>
|
||||
<p>[None of this applies to the Bosch drills and their battery packs.]
|
||||
|
||||
<h2>Instructions for charging in 2018</h3>
|
||||
<p>Please check with a battery nerd whether this is still up to date. It was valid on Friday 27th July 2018.
|
||||
<p> These instructions are for the
|
||||
Pro Peak/ Makita Charger [photo needed]: This will charge all Makita drill batteries.
|
||||
This is the charger which has the Makita slide-socket for the battery which is connected to the yellow ProPeak box.
|
||||
<h3>Short Instructions</h3>
|
||||
<p>First insert the battery.
|
||||
<p><img src="i/propeak.jpg" align="right" hspace="10px"/>
|
||||
<p>
|
||||
Check that screen looks like this: Displaying <br>
|
||||
|
||||
<p class="bluedisplay">
|
||||
LiIo CHARGE<br>
|
||||

|
||||
</p>
|
||||
<p>If this is not the case then move to the long instructions.
|
||||
<br><br>
|
||||
<p>If it is showing <em>exactly</em> as shown above, hold down the "<b>Enter, Start Stop</b>" button
|
||||
(the one at the <b>right-hand end</b>, the <b>4th one from the left</b>) for two seconds.
|
||||
The screen will display "battery check" and then start charging.
|
||||
<p>The screen will then look something like below
|
||||
(but with different numbers) when charging:
|
||||
<p class="bluedisplay">

|
||||
</p>
|
||||
|
||||
<p>If this is not the case then move to the long instructions.
|
||||
|
||||
<h3>Long Instructions</h3>
|
||||
<p>First insert the battery.
|
||||
<p>If the charging screen is not displaying the settings shown above then the correct <b>charging settings</b> need to be selected.
|
||||
You can do this as follows.
|
||||
<ul>
|
||||
<li>First using the "<b>Batt Type</b>" button (First from the left) cycle through the settings until <b>Li-ion</b> is displayed.
|
||||
<li>Next using the "<b>Enter, Start Stop</b>" button (4th from the left) select the "<b>C=</b>" field
|
||||
(this will flash when selected) then increase or decrease the current using the "<b>Inc</b>" or "<b>Dec</b>" buttons
|
||||
(2nd and 3rd from the left) until <b>3300mAh</b> is displayed.
|
||||
<li> Using the "<b>Enter, Start Stop</b>" button cycle to the next "<b>Vp</b>" field. Again use the "<b>Inc</b>" or
|
||||
"<b>Dec</b>" buttons until <b>14.4Vp</b> is displayed.
|
||||
</ul>
|
||||
<p>Now hold down the "<b>Enter, Start Stop</b>" button for 2 seconds until "<b>Battery Check</b>" is displayed
|
||||
and the screen looks similar to below, but with but with different numbers:
|
||||
|
||||
<p class="bluedisplay">
|
||||

<h2>Background knowledge about drills and batteries</h2>
|
||||
<p>This information will not go out of date.
|
||||
<h3>Drills - read this!</h3>
|
||||
<p>Note that the drills have no battery-voltage monitoring at all, and the
|
||||
monitoring circuit in the battery is bypassed when connected to the drill. Thus the drill can easily be used to over-discharge a

must not be left at <2V for any length of time as they rapidly
|
||||
(hours/days?) degrade to useless in this state (and that pair will
|
||||
need replacing - which means reassembling it back in Cambridge and welding in a new cell pair).</p>
|
||||
|
||||
<h3>Makita charging protocol issues</h3>
|
||||
|
||||
|
||||
<p>Makita have put very 'conservative' software in the batteries (as bought) which
|
||||
will stop them working on an as-bought, unmodified Makita charger, even when they are in
|
||||
fact fine. The monitoring board in the batteries is powered from the 1st cell pair so
|
||||
that pair tends to get discharged more than the others when left
|
||||
sitting for the 11 months of not-expo. If an unbalanced (or
|
||||
over-disharged, or too-hot) pack is inserted into the Makita charger
|
||||
the charger and battery will do serial-comms negotiation, the charger
|
||||
will refuse to charge the battery and <em>the battery will remember</em> this.
|
||||
If you try this 3 times, the battery will mark itself bad and will
|
||||
never charge again on a Makita charger. Only a replacement circuit
|
||||
board in the battery can fix this (or new software if we knew how to nobble it).</p>
|

<p>Such batteries are normally still fine and charge on a sensible (RC
|
||||

|
||||
chargers) charger, possible after a "balance charge" to get the cells in
|
||||
the pack in sync again. Expo has a couple of chargers capable of doing a "balance charge" (Yellow Pro-power
|
||||
Prodigy II). Unfortunataly Makita don't build the 14.4V packs with
|
||||
the necessary connections to the cells, so the circuit board in the battery has to be replaced to
|
||||
make this work easily for expo. For 2018 this was done for 7 of our
|
||||
packs, and 3 automatic balance chargers were built by Wookey.</p>
|
||||
|
||||
|
||||
|
||||
<h2>Instructions for charging</h3>
|
||||
Further explanation: the charger uses a different pair of electrical connections from those used by the drill - that's why there are
|
||||
not just two electrical connectors in the charger - to accommodate those extra connections.
|
||||
|
||||

<h3>Types of charger</h3>
|
||||
<p>We have these types of charger; the non-mains chargers are all at top camp and can run all night using the car batteries:
|
||||
<ul>
|
||||
<li>Makita green/turquoise plastic as-bought mains-powered charger - only at base camp.
|

<li>ProPeak/Makita charger - a yellow ProPeak box with a blue LCD display connected to the green battery slide connector cut out from a Makita charger.

<h3>Makita batteries: taped and un-taped</h3>
|
||||
|
||||
<p>If a battery has green insulation tape on it it has been
|
||||
modified by us and <b>will not charge</b> on an unmodidfied as-bought Makita charger.
|
||||
<ul>
|
||||
<li>Taped batteries must be charged on the balance pp (or RC chargers).
|
||||
<li>Untaped (standard, as-bought) batteries will not charge on the balance chargers, so must
|
||||
be charged on the Makita charger (or RC charger).
|
||||
</ul>
|
||||
All batteries will
|
||||
charge on the RC chargers, but not as fast as on the as-bought (mains power only) Makita
|
||||
charger. Go to <a href="#RCcharge">RC charger</a>.</li>

<h3>Makita charging protocol issues</h3>
|

<h3>Using Makita mains charger</h3>
|
||||
|
||||
<p>Makita have put very 'conservative' software in the batteries which
|
||||
will stop them working on the Makita charger, even when they are in
|
||||
fact fine. The monitoring board is powered off the 1st cell pair so
|
||||
that one tends to get discharged more than the others when left
|
||||
sitting for the 11 months of not-expo. If an unbalanced (or
|
||||
over-disharged, or too-hot) pack is inserted into the makita charger
|
||||
the charger and battery will do serial-coms negotiation, the charger
|
||||
will refuse to charge the battery and the battery will remember this.
|
||||
If you try this 3 times, the battery will mark itself bad and will
|
||||
never charge again on a makita charger. Only a replacement monitoring
|
||||
board can fix this (or new software if we knew how to nobble it).</p>
|
||||
<p>This is the green/turquoise charger with 3 LEDs, and diagrammatic charging info on RH side. Charges at up to 100W.</p>

|

<ol>
|
||||
<li>Make sure charger is powered (flashing green LED).</li>
|
||||
|
||||
<li>Slide battery into Makita charger. It should start charging.</li>
|
||||
|
||||
<li>Look at the LEDs for status - the legend is printed on the charger.
|
||||
If it flashes 'broken battery' (flashing red and gren LED) at you
|
||||
after a few seconds, use the yellow (Pro-Peak Prodigy II) charger instead.</li>
|
||||
|
||||
<li>Eventually it should show '100%' (steady green LED) (in about 1

hour max). You are done.</li>

<h3>Using Balance charger</h3>
|

<p>This is the set of 3 (2 half-width) chargers made from old green/turquoise Makita chargers.
|
||||
They have a set of 4 LEDs. (The full-width one only has 1 LED in 2018). Charges at 40W.</p>

<ol>
|

<li>Make sure charger is powered (flashing green LEDs).</li>
|
||||
|
||||
<li>Plug batt into charger. After a few seconds it should start charging.</li>
|
||||
|
||||
<li>Look at the LEDs for status - the legend is printed on the RH end charger. Steady red for bulk charging to 80%. Steady orange for last 20% charging. Steady green for finished. If it flashes red and beeps (repeated 5 times) something is wrong - see table. If you get an 'undervoltage' reading, use an RC charger instead to get the charging started.</li>
|
||||
|
||||
<li>Eventually it should show '100%' (steady green LEDs). (1hr 50 max possible charge time). You are done.</li>

|

down "<b>Enter, Start Stop</b>" button

<li>If it shows '<b>4</b>' as the number of cells, then press "<b>start/enter</b>"

again. Charging will start (fan comes on, display changes). If it
|

shows anything else like '<b>polarity reversed</b>' or '<b>connection break</b>'
|

then fix the connection to the battery. If it shows '<b>3</b>' as number of

|

|

<li>Once it beeps and says 'FULL' (flashing) then you are done (should

be less than 2 hours). Display shows number of mAh put in in

<hr />
|
||||
|
||||
<p>Such batteries are normally still fine and charge on a sensible (RC
|
||||
- Radio Control, because RC people are the main market for these
|
||||
chargers) charger, possible after a balance charge to get the cells in
|
||||
the pack in sync again. Expo has a couple of these (Yellow Pro-power
|
||||
Prodigy II). Unfortunataly Makita don't build the 14.4V packs with
|
||||
balance connections to the cells, so the PCB has to be replaced to
|
||||
make this work easily for expo. For 2018 this was done for 7 of our
|
||||
packs, and 3 automatic balance chargers built.</p>
|
||||
|
||||
<p>Note that the drills have no battery-voltage monitoring at all, and the
|
||||
monitoring circuit is bypassed when conected to the drill (the charger
|
||||
uses a different connector-pair from the drill - that's why there are
|
||||
3 slots). Thus the drill can easily be used to over-discharge a
|
||||
battery, so please stop drilling when it gets slow and put on a new
|
||||
batt, unless it's an emergency. Drilling with an excessively-sagged
|
||||
voltage is a good way to knacker the weakest cell-pair. If your battery
|
||||
does get to this state, try to charge it up as soon as possible. Cells
|
||||
must not be left at <2V for any length of time as they rapidly
|
||||
(hours/days?) degrade to useless in this state (and that pair will
|
||||
need replacing).</p>
