[DeTomaso] NPC: Losing caps on my battery

[Tomas Gunnarsson]

Are you installing sealing caps where venting caps where supposed to be installed perhaps? Some batteries have "leaking" caps and are otherwise sealed while others have sealing caps and vent separately. Simple test is to measure battery voltage at 2-3000 rpm.
