I have a motorhome with two 12v 110ah leisure batteries. I have no idea how old the leisure batteries are, the motorhome is 20 years old and still operating on the original charger! I suspect the charger wasn't designed to maintain two leisure batteries and this is why I purchased a Victron Energy Blue Smart IP22 Charger 1230(3) 230V charger.
It became clear the existing leisure batteries weren't lasting as long as they should powering mainly LED devices. I did what many do and replaced the batteries with new.
I've used the Victron Energy Blue Smart IP22 Charger to condition (Normal Condition) the old batteries and everything seems to have proceeded without issues BUT, how can I be sure the old batteries have been restored to a good/original capacity? I that the purpose of 'conditioning'?
Any comments/tips would be most welcome :)
