What type of battery can a 1V charger have? Is it a 1A charger?
If you are talking about using a 5V, 1A (1000mA) charger for a 3.7V, 1450mAh lithium battery, charging takes about less than 2 hours to fully charge.
Generally, the discharge voltage of rechargeable batteries is greater than 1V, and it is impossible to charge them with a 1V charger.
Please take a closer look at the battery type which it is about. East. If not, tell me more carefully.
