Yes, LiFePO4 is inherently safe and recognized as the most stable type of lithium battery available. Power Queen lithium cells are UL certified, ensuring they meet the highest safety and sustainability standards. Each Power Queen LiFePO4 battery is equipped with an internal Battery Management System (BMS) that provides protection against under-voltage during discharge, over-voltage during charging, over-current during discharge, over-temperature during both charging and discharging, and short circuits, thereby safeguarding the battery cells from damage. Moreover, Power Queen LiFePO4 lithium batteries have been rigorously tested to confirm they pose no risk of fire or electric shock, even in harsh environments.

LiFePO4 batteries can be safely charged within a temperature range of 32°F to 113°F (0°C to 45°C). The Power Queen 12V 100Ah Deep Cycle Lithium Battery features low-temperature charging protection, which automatically stops charging if the battery cell temperature falls below 32°F. This function prevents damage to the battery cells when charging in freezing conditions.

It is recommended to store LiFePO4 lithium batteries at a 50% state of charge (SOC). For prolonged storage, it is advisable to cycle the batteries at least once every six months. Recommended storage environment: 10℃～35℃ (50℉～95℉），45%RH～75％RH.

The length of time a 12V 100Ah battery will last depends on the amount of current drawn from it and the specific use. You can estimate this by using the following formula:

Battery life (in hours) = Battery capacity (in amp-hours) / Load current (in amperes)

For example, if we assume a load current of 10 amperes:

Battery life = 100Ah / 10A = 10 hours

This means you can expect approximately 10 hours of continuous operation with a 10-ampere load. However, actual duration can vary based on factors such as system efficiency, changes in the load current, and the overall condition of the battery.
