Deep Cycle Gel Battery 12v 75ah


Renogen Deep Cycle Gel batteries utilise gel electrolyte technology, which holds the battery plates securely in an immobilised gel.  This design makes Deep Cycle Gel batteries extremely robust and resistant to spillage if accidentally tipped upside-down.

The range is completely maintenance free, requiring no topping-up of liquid electrolyte, whilst the valve-regulated sealed design enables installation in hard to reach locations.


Description

Key product features:

●  Gelled electrolyte made by mixing sulfuric acid with silica fume.
●  The electrolyte is gel like ,immobile and does not leak ,enabling
uniform reaction of each part of the plate .
●  High rate discharge performance due to tight assembly technology
●  Strong heat dissipation and wide operating temperature range
●  Avoid acid mist being separated out , environment friendliness
●  Efficient venting system release excessive gas automatically

 

Applications:

●  Solar and wind energy storage system
●  EPS and UPS battery backup
●  Signal system , emergency lighting system , security system
●  Telecommunication Equipment
●  Power plant and transmission system
