<h1>Drill Battery Charging</h1>
<h2>Instructions for charging</h3>
0) <li>If the battery has insulation tape on it (red or earth) it won't
charge on the Makita charger (feel free to confirm this). Go to <a href="#RCcharge">RC charger</a>.</li>
<h3>Using Makita charger</h3>
<ol>
<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-power RC charger instead.</li>
<li>Eventually it should show '100%' (steady green LED) (in about 1
hour max). You are done.</li>
</ol>
<h3 id="RCcharge">Using Pro-Power (or Accucell 6) RC charger</h3>
<ol>
<li>Make sure charger is powered (display lit up)</li>
<li>Connect charger to battery (either hardboard adaptor or empty
Makita base adaptor). Check polarity is correct with hardboard
adaptor.</li>
<li>Check display says 'Lion' or 'Lipo' and '14.4V' and '3A' and 'CHARGE'. Hold
down 'start/enter' button (on right). It will do a battery check.</li>
<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.</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
bottom right. Should be a number like 250 for each hole drilled
(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. 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 (few mins?).
</p>
<h3>What sort of batteries are they</h3>
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. They can be charged at up to 3A rate.
