why does this battery not have the specific feature of "Battery includes built-in protection against over voltage, over current, and minimum voltage." that the 1100 mAh and 100 mAh batteries do?

That's a good question. The 2000mAh battery has the same protections listed in the Safety Test section of the data sheet as the 100, 860 and 1100mAh batteries.

Does this battery have a inbuilt overcharge/overcurrent/discharge protection pcb like the other li-ion batteries or not?

Hi I very elementary question: Does this then mean that I can charge my battery, with a Li-Po charger of course, with a 5V mini-USB wallwart that came with my cell phone? Thanks

Hi That is the charger I own; I bought it when I bought the batery. What I'm curious about is whether or not a 5v cellphone charger plugged into the mini-USB on the li-po charger is appropriate? Thanks Christian

(That is the charger I own; I bought it when I bought the battery. What I'm curious about is whether or not a 5v cellphone charger plugged into the mini-USB on the li-po charger is appropriate?) yes you can Motorola chargers are cheap and plentiful As long as it has mini-usb connector on it
