VRLA Battery 12V 70AH | Dimension: 350x167x178x178mm
GRANKIA FG70-12 12v 70ah agm deep cycle battery for alarm system offers excellent performance in a wide range of applications including security and fire systems, medical devices, emergency lighting and UPS systems.
Flame Retardant ABS case and cover to UL 94 V-O for superior performance. Proven VRLA Absorbent Glass Mat (AGM) Technology that guarantees safe operation without maintenance and “non-restricted article” status for transportation.
Valve regulated sealed lead acid 12v 70ah agm deep cycle battery charges up to two times faster than conventional alternatives. No need for checking Electrolyte level and topping throughout its life. Sealed construction Ensures no leakage of Electrolyte from Terminal or casing.
Absorbent glass mat (AGM) is a class of lead-acid deep cycle battery in which the electrolyte absorbs into a fiberglass mat. The plates in an AGM battery may be flat like wet cell lead-acid battery, or they may be wound in a tight spiral.
Basically, an AGM battery will always have a flat top, and only the negative and positive terminals of the battery will be sticking out. On the other hand, the liquid acid batteries have a removable top which is not the case with AGM batteries as they are properly sealed.
They should be recharged when they indicate a 50% charge, but never let them get lower than 20% to ensure a long life. Lead-acid batteries, such as deep cycle batteries, run the risk of sulfation if left uncharged for too long.
