Lead Acid Batteries
Sometimes known as VRLA or SLA - lead acid batteries are still the most cost effective solution to many high capacity rechargeable applications.
Not all lead acid batteries are the same. The main attributes to consider are:
Not all lead acid batteries are the same. The main attributes to consider are:
- Usage - standby (trickle charge) or cyclic (more complete charge/discharge)
- Service life (number of years in use)
- Power/current requirement
Gel VRLA technology offers significant benefits of robustness and thus cycle life over traditional AGM technology.
