Drill Battery Charging

Instructions for charging

+0)
  • 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 RC charger.
  • + +

    Using Makita charger

    + +
      +
    1. Make sure charger is powered (flashing green LED).
    2. + +
    3. Plug batt into Makita charger. It should start charging.
    4. + +
    5. 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.
    6. + +
    7. Eventually it should show '100%' (steady green LED) (in about 1 + hour max). You are done.
    8. +
    + +

    Using Pro-Power (or Accucell 6) RC charger

    + +
      +
    1. Make sure charger is powered (display lit up)
    2. + +
    3. Connect charger to battery (either hardboard adaptor or empty +Makita base adaptor). Check polarity is correct with hardboard +adaptor.
    4. + + +
    5. 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.
    6. + +
    7. 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.
    8. + +
    9. 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).
    10. +
    + + +

    Can I tell if a battery is already charged?

    + +

    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?). +

    + +

    What sort of batteries are they

    + +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. + + + + diff --git a/handbook/index.htm b/handbook/index.htm index b7ff5ad34..215463816 100644 --- a/handbook/index.htm +++ b/handbook/index.htm @@ -20,6 +20,8 @@
