What is the kind of battery used? Thanks!

Rodrigo Lopez - Reply

Hi Rodrigo, the Oontz Angle 3 uses a rechargeable 2200mAh lithium-ion battery. Happy Fixing!

the one that I have has a "circuit board" attached to the battery. Is this what controls the recharging? If so, where do you get the battery with these?

Hi Rob,use soldering iron disconnect the circuit board which come with old battery you going to replace, and soldering iron the disconnected circuit board back onto your new battery. The so called circuit board is to protect the battery from over discharge or over charge. Hope this help.

Do you know the watt hour rating for this battery?

If you don't know the watt hour rating, can you tell me whether this battery is 2200 mAh and 3.7v?

One can also replace the battery with what looks like a 18650 lithium-ion sized battery; they range in size from a minimum from 2,200mah to 3,400mah; so technically one could also upgrade the lithium-ion sized battery up to the maximum 3,400mah size and thus upgrade oneself from 10 hours continuous play to 15 hours of continuous when one uses the 3,400mah sized lithium-ion battery instead of the 2,200mah lithium-ion battery.
