You don't want automotive lead acid - they vent hydrogen and tend to splatter - every one I've seen has corroded the inside of the enclosure.  The vented hydrogen can also be an unpleasant bomb in a closed area like the inside of equipment. What you need is a "sealed lead acid" although even that name is misleading as the majority of those are actually gell (cells with a gelled acid solution) which makes them spill proof.  These are also rated for extended or trickle charge without damage to the battery - important as nearly all UPS batteries are seldom discharged compared to the time they spend waiting with just a trickle charge. -- Will Honea <whonea@whonea.net> Iscrizione modo messaggi Iscrizione modo riassunto Iscrizione modo index Cancella Scrivi al Listmaster
