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:
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.
