Ellies Deep Cycle Calcium Battery (Standby) (102Ah)(12V)

The Royal calcium battery is a general purpose semi-sealed battery with a design life up 3 to 5 years in standby service. Royal batteries uses specially alloyed calcium-lead, which leads to extrememly low levels of "electrolyte decrease".

Therefore there is no need to supplement distilled water if the charging system remains error-free. Special liquid-gas separators keep the electrolyte inside. An electrolyte is any substance containing free ions that behave as an electrically conductive medium. These separators are also used between the positive and negative plates of a lead acid battery to prevent a short circuit through physical contact. No filler caps are required therefore there is no electrolyte contamination, overwatering or damage in use.

Unique wrought lead-calcium grid design means less internal corrosion and ecient current conductivity for more power and longer life. It also cuts gassing, resists overcharge, heat and thermal runaway.
