Non Spillable Valve Regulated Lead Acid Rechargeable Battery 12v 18ah UPS EPS Power Supply
1. battery for solar Sealed/Maintenance–Free
The valve regulated spill proof construction allows trouble-free safe operation in
any position. There is no need to add electrolyte, as gases generated during
the charge phase are recombined in a unique “oxygen cycle”.
2. Long Shelf Life
A low self-discharge rate, up to approximately 3% per month, may allow storage
of fully charged batteries for up to a year, depending on storage temperatures,
before charging becomes critical.
3. Deep Discharge Recovery
Special separators, advanced plate composition and a carefully balanced
electrolyte system ensure that the battery has the ability to recover from
excessively deep discharge.
4.Low Pressure Valve Regulators
All batteries feature a series of low pressure one-way relief valves. These
valves safely release any excessive accumulation of gas inside the battery and
5.High Discharge Rate
Low internal resistance allows discharge currents of up to ten times the rated
capacity of the battery. Relatively small batteries may thus be specified in
applications requiring high peak currents.
