GRANKIA FG5-12 valve regulated lead acid 12v alarm battery 5ah is made with a hardened ABS plastic to protect against spills and leaks. The charging reaction converts the lead sulfate at the negative electrode to lead. At the positive terminal the reaction converts the lead to lead oxide. As a by-product of this reaction, hydrogen is […]
GRANKIA FG4-12 valve regulated sealed 12v lead acid battery 4ah is a rechargeable battery that uses lead and sulphuric acid to function. The lead is submerged into the sulphuric acid to allow a controlled chemical reaction. The 12v lead acid battery is formed by dipping the lead peroxide plate and sponge lead plate in dilute […]
GRANKIA FG4.5-12 small valve regulated lead acid battery 12v 4.5ah can be used in enclosed and indoor environments without leaking or maintenance, providing a superior performance. The lead–acid battery consists of two electrodes submerged in an electrolyte of sulfuric acid. The valve regulated lead acid battery 12v 4.5ah consists of electrodes of lead metal (Pb) […]
GRANKIA FG160-12 lead acid deep cycle solar battery 12v 160ah is designed for the prolonged, repeated, and deep charging/discharging cycles needed to store and distribute energy generated. For this reason, car batteries cannot be used as solar power batteries. If kept in a charged state when unused, the common lifespan of deep cycle solar battery […]
