This is a rechargeable lithium-ion battery with a built-in USB charging port. We will provide a USBC charging cable.
Compared with the original NiMH battery,
you can understand that the original battery is 1.2V * 1200mAh, and the power is about 1440 mAh
Our battery is 3.7V *880mAh, and the power is about 3256 mAh
There may be some loss in actual use, but the actual capacity of lithium batteries is much greater than that of NiMH batteries.
The characteristics of lithium batteries are stable voltage and will not suddenly shut down when the battery is low.
The battery has its own indicator light, which will remind you when the battery is low.
So lithium batteries are a better choice.
