You can actually reuse these batteries... My Battery Pack stopped recharging so i tore it down and relized these are just regular rechargeable AA batteries... and i have an old charger for rechargeable AA or AAA batteries so i popped them inside it and plugged it in and sure enough it charges them and they still hold a charge for quite a long time

so I can just order batteries with the 1.2VDC 2100mah specs and replace the ones in the pack now? Any tips on soldering the batteries so I don't ruin them (rookie solderer here).

Well, actually you can use any rechargeable AA's! the Mah number just stands for how long it will last on one charge, the larger the number, the better, of course, it would take longer to charge, but who doesnt want a longer battery life?! also, when soldering a battery, i usually take some sand paper, and get a good rough surface on them, for the solder to stick to! dont worry too much, it wont ruin them! it would burn your hands before it got too hot for itself!

Uhhh, nah. Check if the batteries you want to put in the pack are NiMH or NiCd. If you put the wrong type in they will melt. Make sure the type matches the original. The ones in these pictures are NiMH.

I took mine apart, and realized a couple things. 1) My batteries look dark green, and dont have any numbers/writing on them. 2) There are two wires going from the charging contacts to the batteries sealed with something white. It broke off. Could that be the reason that my charging no longer receives a charge?

I believe that will be the temperature sensor, on the pictures it appears to be on the main board, but in my battery unit (uk) it is on long black wires and placed between the battery's and the outer case. Did you ever solve the non charging issue?

Correct me if I'm wrong, but doesn't that say 2100mah, not 1200mah?

[Psycosisnine]

you are correct!
