OK, so I have a battery question about Li-ions.
I have a battery pack with a charger, from a makita 10.8v (this one Makita LCT204W 10.8v Cordless 2 Piece Drill Driver + Impact Driver Kit + 2 Lithium Battery 1.3ah : Tooled-Up.com).
The batteries in the unit are dead; they are SE US18650VT (second line T C112VSL19J) models. This pack contains 3 18650's in series through a charge controller, and the pack is rated at (3.6 x 3= 10.8v) 1300mAh, my question is this: When plugged into a charger will the charger aim to reach the optimal voltage (4.2v for li-ions?) after a preprogrammed mAh has been reached (which would at best render the batteries unusable after one or two charges, at worst cause a discharge meltdown/explosion/really bad shit) OR
The voltage is not reached until the battery is full, and only the voltage affects charge time directly, current is not monitored by the charger at all. I have been searching for an answer to this question for weeks lol, please help as it directly influences rebuilding all battery packs with product specific chargers. Thanks, and have some cake.:bday:
Basically can I stick some li-ions with a higher mAh rating into the pack and get longer out of it? Providing they have the same discharge rating.
