I checked the data sheet and they are 2400 mAh capacity and rated at 4000 mA discharge current maximum, 4.2 volts full charge and 3.75 volts nominal charge, and 3 volts discharged. Take this with a grain of salt because lots of variables effect internal resistance, but generally a number around 230 miliohms is a good figure. Location: Ballard; One battery provides extra battery power for an average of 25 minutes of extended run time on carpet and hard floors. Set the current to something like 200 mA and start charging.

Using any other charger could cause the lithium-ion cells to overcharge and result in a fire. Multi-cell packs have an added feature called a battery management system with a balance function that monitors and distributes charge current and voltage across each cell, making sure each gets charged with the same amount of current and voltage. In case you've ever wondered, the name of the battery contains its dimensions. Lithium cells in battery packs are always connected by spot welded tabs that connect the positive and negative terminals and you need to be careful when cutting them. Monitor the voltage until it gets above 2.8 and stop the charging process. Most all lithium-ion battery packs or single batteries have some kind of protection circuitry built into them to protect the cell from being overcharged, short circuited, or over discharged. Pry the case apart if needed and dig out the goodies inside. That said, you must use an appropriate charger, either for single cells or one that supports multiple cells in a pack such as a balance charger. Hold the red clamp on the positive end and black on the negative end of the rechargeable battery for no longer than three seconds. I say optional because practical gloves for this task probably won't stop a sharp screwdriver blade or utility knife blade that's slipped out of a joint at high velocity.
