The design principle of the HOPPECKE sun | power VR M 2V 890Ah + cable batteries is based on the use of flat lead plates with a glass fiber mat as separator in which the electrolyte is absorbed. sun | power VR M batteries are maintenance-free, filling with distilled water is not necessary.
In addition, this battery has an excellent number of life cycles and is very efficient in absorbing the charging current. Due to the optimization of the internal construction (lead mass and electrolyte), these batteries are very suitable for solar applications. The shock resistance and polypropylene housing ensure that the battery is resistant to mechanical influences from the outside.
The handles are comfortable and integrated in the battery.
