To provide a stable DC power supply, supporting backup power, energy storage, and startup power functions.

The lifespan is generally 3 to 5 years, while deep-cycle types can last over 8 years.

The FT model has deep cycle capability, making it particularly suitable for energy storage systems.

The self-discharge rate is ≤3% per month, which is lower than other lead-acid batteries.

High-current discharge requires reviewing technical specifications. If needed, please inquire about specific high-rate battery models designed for high-current discharge.

MEAN WELL uses VRLA (Valve Regulated Lead‐Acid) batteries, which do not require water refilling.

Leoch lead-acid batteries are designed with a sealed structure, ensuring complete leak protection.

Battery performance is significantly affected by environmental temperature. 
It is recommended to avoid excessively low or high temperatures and maintain an optimal operating temperature of 25°C.

Overcharge protection requires the use of a dedicated charger.

Yes, but battery consistency must be ensured.

Yes, it is suitable for UPS and backup power systems.

Yes, especially models with no acid mist emission are highly recommended.

The charge and discharge efficiency is greater than 90%.

No memory effect; they can be charged and discharged at any time.

For a 12V battery, the float charge voltage ranges from 13.38V to 13.62V, and the equalization charge voltage ranges from 14.1V to 14.4V.

Yes, but it requires a dedicated fast charger to avoid damage.

The DJM series ranges from 5.5 to 10.0mΩ, and the FT series ranges from 4.3 to 9.0mΩ, depending on the specific model.
