Restore Resurrect Battery?

[Winston001]

Anyone had a go at flushing and restoring a dead battery? I'm giving it a try at the moment and wonder if anyone has any tips.

[FJRider]

My tip ... buy a new one.

[Sable]

It's not expensive.

It's not expensive.

If you bought a Shorai you may not need to worry about your battery for up to 8 years...

I wondered when you'd show up ...

I guess it pays to replace with new. I have tried to drag out battery life in the past and put up with having to charge battery every night but eventually you will get let down at the most inopportune time.

Have you got some sort of siren wired up that goes off any time anybody mentions "battery"?

Thanks Orangeback, appreciated. The product will be Tetrasodium EDTA which is a chelating agent and appears a bit hard to find on the net. The purpose of a chelating agent is that it dissolves the lead-sulphate crystals which build up on the battery's lead plates. Most batteries die of sulphation. Essentially the sulphate deposit covers the plates and prevents the sulphuric acids reaction with the lead required to produce free electrons.

A simple cheap alternative is magnesium sulphate = Epsom Salts. $2.50 for 500gm in the supermarket.




As for the rest of you, very very silly. A chap asks an intelligent question and is greeted with buffonery. I spurn you as I would a rabid dog, I wouldn't join your vacuous discussion even if you went down on your lousy stinking bended knees and begged me.

The short answer is yes, it can be done successfully.

I remember many years ago watching a video on how to do this, complete with melting the pitch on the top of the battery to remove the cells, stripping the separators out and cleaning the plates. Don't know that I'd be so keen on attacking a battery with a blowtorch, but I guess H&S and HR departments weren't so prevalent back then.

Basically, if you dissolve the sulphation off the plates and they're still there after you're finished, fill it up with fresh acid and charge it and it's effectively a new battery.

Good on you Neels.

It is possible to zap a dead battery with a welder using a diode apparently but it sounds a bit dangerous to me. Plus electronics is not my strong suit.


For everyone who says just buy a new one - yeah, understood. But there are supposedly 98 million wet cell batteries dumped every year in the world and that offends the conservationist in me. Plus...I like a challenge. Over and above that, the specific battery I'm annoyed with belongs to a tractor and costs $300 to replace. That's a lump of change for something only used a few times a year - and consequently only lasts a year. My bike battery has the same problem but somewhat cheaper.
