Looks like my repaired battery tray and hell hole were christened by my new battery based on the white residue and light rust forming in the tray. (IMG:style_emoticons/default/dry.gif)
From what I’ve read in posts, I’m thinking voltage regulator and/or alternator as a probable cause. Any words of wisdom for someone new to electrical system troubleshooting and battery acid damage control? |

Since they are gell filled, they don't overflow nor need to vent. They can take a charge higher charge than you would expect. But you really need to check the charging circuit.

But you really need to check the charging circuit. I have an orbital which is a different brand but the same technology. It states on the battery that the voltage should never exceed 14.5 volts. I have gone through 2 of these and I believe the charging circuit may have damaged them (that and excessive drain) I think lead acid will tolerate the higher voltage but you risk boiling over problems. Lead acid is O.K. if you keep the area clean and no exposed unpainted metal. |

Forget lead acid & fix the charging system or keep buying gel/dry batteries, as the body repair will cost far more, if not a total loss due to an engine bay fire when the acid eats your fuel lines & connections! BTW - Here is a clean, neutralized & painted battery tray with no battery in there at all May 85 to May 09 (24 years) in my dry SoCal garage - this is what just the residual acid does even after cleaning/neutralizing!!!!

(IMG:style_emoticons/default/sad.gif) (IMG:style_emoticons/default/hissyfit.gif) My main point is that if the charging system is not working properly and you are over charging a lead acid battery, then installing a gel battery is not a good solution. Fix or make sure the charging system is working properly before installing a gel battery. If you have circuits that drain the battery when the car is off, fix them. Gels are easily damaged by allowing them to drain excessively or overcharging. If running a lead acid, keep the area clean. and wash frequently. |
