This is a rechargeable Lithium polymer battery with a built-in USB charging port. We will provide a USBC charging cable.
Compared with the original Lead-Acid Battery ,
you can understand that the original battery is 2V * 470mAh, and the power is about 940 mAh
Our battery is 3.7V *1100mAh, and the power is about 4070 mAh
There may be some loss in actual use,
but the actual capacity of lithium batteries is much greater than that of Lead-Acid Batterys.
The characteristics of lithium batteries are stable voltage and will not suddenly shut down when the battery is low.
With charging indicator light
So lithium batteries are a better choice.
