[RE-wrenches] Advice Needed: L16 Accident! Damage Questions

[Bob-O Schultze]

And if you do use them, I'd replace the spilled electrolyte with electrolyte, not water. I'd make the battery store do that for you if they poorly wrapped the pack for transport. Chances are that the batts were mostly charged when you got them new so most of the the sulfuric acid would have been in solution. Replacing that with water will weaken it.

Hi Jeff,

All of the advice is just that advice.
There is no way to know if there has been damage, regardless of what has happened in other situations.
There are no guarantees you can give your customer


I'm not advocating not using them, only that I would only use them with caution and careful observation for the first days/weeks to see if any problems appear.

As you have already made your margin on the sale, you could offer the replacements at a substantial discount just to cover your time and expenses. I'd decline offering "repairs" or even more than cursory advice that might come back to bite you years from now when one or more cells fail prematurely.
