Rahimafrooz batteries manufactures optus maintenance free batteries that are particularly engineered To conform to major international standards specifications. The rahimafrooz batteries are electrolyte filled and charged from factory ensuring high performance. Features and benefits of the rahimafrooz batteries include: negative calcium and positive antimony plate - negative calcium plates reduce electrolyte loss, no need of frequent top up; calcium and low antimonial grid alloy of 1.7% guarantee minimum water loss and lower maintenance; radial grid geometry lowers the electrical resistance; polyethylene envelope separators improve "cranking performance" because of reduced resistance; enwrapped pocket separators safeguard against short circuits; built-in charge indicator helps to determine the state of charge of the battery; built-in flame arrester vent plugs are specially designed to check water loss from evaporation; extremely high starting power even at very low temperature; calcium alloy provides the battery a very low discharge rate; and eco-friendly - all components are fully recyclable to save the environment.
