Hi Guys: For those of us using auto/marine batts for radio use I have a useful tidbit. One of my projects (now in its 5th year and about complete) regenerates 6 & 12V lead acid batteries up to 250Ah. An Angel investor group interested in buying equity handed me a pair of fairly new ACDELCO Voyager ACDM27C 12V batteries drained flat on a member's marine launch. Flat as in 1.7V each! After several hours on a commercial Schumacher 12Amp smart charger they hovered at 2V...so poor result. After an automated 24 hour regeneration (on my 10" cube system)  they recovered to 65% OEM CCA and 50% rated Ah. So abusing starter batts down to literally 0% charge effectively ages them by about 50% or 9 months of regular use. They are not recoverable by normal means and would not be a valid warranty replacement due to the abuse.

Correction, the regen delivered 95% OEM CCA and 50% OEM AH.

That is quite an improvement. Is it possible that it may further improve with several discharge/charge cycles? Is your rejuvenation system some sort of Desulfator? - - - - - - - - - - Sat Apr 8, 2017 7:40 am (PDT) . Posted by: mosaicmerc Correction, the regen delivered 95% OEM CCA and 50% OEM AH.
