Hi, everyone, I have a virtually unused (7 months old) Marine/RV battery that I use as the supply to a very infreqently used DC to AC inverter (12 VDC to
120 VAC) Thus, it sits permanently charged (intermittantly) and unloaded with the invertor OFF, or loaded at 0.6 amp with the invertor ON but unloaded on the AC side. However, I'd rather trickle charge it continuously: A) keep it charged and B) preserve it "forever" as a stand-by unit. Question: at what NET continuous charge current to the battery?The battery is marked: MEGA-TRON Marine-RV Deep-cycle SRM-24 550 CCA 690 MCA SPR I don't know the small current amp.hour rating. Might it be 100 amp.hours? 200? Other? Size is: (LxDxH) 10" x 6 1/2" x 7 3/4"
My guess is that a 0.5 amp NET charge rate is too high (would dry it up?) but 10 mA is too low (less than the charge leakage?), but I'll admit I just don't know (I am not a lead-acid battery expert) but I can design a fixed NET current charger at any given level.
Any other tips for the use of a Marine/RV battery in this service?
Thanks for all replies. Cheers, Roger PS. Above email is false (anti-spam.) Feel free to email me at "analogdino at(ta-boy) rogers dot(ty-as-they-) com(e)", suitably decoded.
