A:AnswerThank you for your patience.
Regarding the 16,000mAh jump starter, under normal storage conditions (around 25°C), lithium-ion batteries typically have a self-discharge rate of about 1-3% per month. This means if fully charged and left unused, it should retain most of its capacity for several months.
However, please note that factors such as high temperatures or the standby power consumption of the device itself may affect the actual duration. To maximize battery life, it is recommended to store it in a cool, dry place and recharge it every 3 to 6 months if not in use for an extended period.
As for the charging time, it takes approximately 5 hours to fully charge.
Please let me know if you have any further questions.
