[RE-wrenches] Air conditioning for batteies in high temperature climate

[Starlight Solar, Larry Crutcher]

Hello Battery Wrenches,

Over the years I have had several battery banks in Baja and Sonora Mexico fail in just 36 to 48 months. These have been L16 or 8D AGM or flooded banks, 24 and 48 volt systems. The charging systems are working properly and programmed to manufacturer recommended set points and discharges are rarely over 30% DoD.  Some batteries are only used on weekends, some are discharged daily.  I believe what is affecting the short life is the high temperature they live in for 5 months each year. Temps. can hit 115 F in vented battery rooms. I have been thinking about a small air conditioner and insulated battery box to keep the battery at no more than 80 F. There are some portable units that draw about 600 watts and the run time would be very little with a highly insulated enclosure. There is ample power to do this on the home I am changing batteries in now. Has anyone done this and gained longer battery life?

Best Regards,
