*ROCKET ESC 100-12 FR Battery Summary*
The ROCKET ESC 100-12 FR is a 12V 100AH sealed maintenance-free rechargeable battery made by Global Power Source Group in Vietnam. It uses AGM/VRLA technology, which means it’s sealed, non-spillable, and doesn’t require adding water. The “MF” stands for Maintenance Free and the battery is designed for both deep cycle and standby applications, making it reliable for solar systems, inverters, UPS units, and telecom backup.
In terms of charging, it has two main settings at 25°C. For stand-by use, the recommended voltage is 13.5V to 13.8V with no initial current limit. For cyclic or regular deep cycle use, it should be V to 15.0V with a maximum initial current of 25A. This flexibility allows it to work well in both backup power setups and daily discharge/recharge systems like solar.
