Hi all
Jenny has just scored 18 x 6v 70AH wet cell batteries that are usually for submarine duty. They've been written off as near-new by her company and she is able to get the whole lot.
Question - how do you keep these in good condition when we're not yet ready to deploy them at our property?
My guess is to gang them up by connecting them together in set of two, in serial, to make 9 x 12v banks. Is it kosher to then join these 9 x 12v banks in parallel, resulting in a conglomerate bank with 630AH capacity? Can this huge bank then be trickle-charged by a normal car battery charger that charges at 15 amps and will trickle when the system reaches 14-odd volts?
TIA
