If the electrolyte is gassing away on only 500 miles running, its almost guaranteed to be overcharging. Only top up with distilled water - *NEVER* add acid, except to replace spillage.

Actually it's a CLASSIC proof of cause..but what would an uneducated idiot like you know about the basics.

Thank you so much for proving my point.

As long as you keep thinking that way, you're going to continue to add too much water to your flooded cell lead acid batteries and you're going to have to keep replacing them due to sulfation. > > Only top up with distilled water - *NEVER* add acid, except to replace > spillage. Who ever said anything about adding *acid* to a battery that has a low electrolyte level? I've been talking consistently about adding *electrolyte* to fully charged batteries that have low electrolyte levels. Why don't you gays get it? |
