Battery Pack's not holding Charge
2007 Aixam 500.5 Mega City Electric Car

I have bought a 2007 Year Mega City Electric Car which has only done circa 3000 Miles. Due to this lack of use the Batteries of which there are twelve Lead Acid units have been left uncharged for some time. Does anyone know of a way to reinvigorate these Batteries without the need to replace them. I have seen the relevant videos on Youtube re Epsom Salts, Alum, Battery Chem etc but do any of these options work and would they affect the overall distance capacity of the Car.

Thanks in anticipation.

disconnect the Battery packs and charge the Batteries in pairs with a 24V Charger after connecting the Batteries in Series. It speeds the process up if you can get your hands on a few 24V Chargers.

Done as above some time back and operating excellently since.
