3.7V 4000mAh 3377128 Rechargeable Lithium Polymer Battery Length 130mm
The battery in my tablet lost capacity and needed recharging after about a hour of use. I ordered a replacement from YDL battery, it took awhile to arrive about 2 weeks. I ordered the 4000mAh. I should have ordered the 6000 mAh. But 4000 mAh works ok. The battery comes with a connector which I can't use as the battery is soldered to the circuit board. I removed the plastic housing and soldered the metal pin connector to the board. The tablet is charging and running as before.
