Battery rejuvenation

I have restored 2 vehicle batteries that the charger showed up as f---ed by using them on the electric fence for one week only then slow charging again. alternate 2 batteries this way and within a month both were showing battery full on the charger and tested ok under load as well. I have no idea why this should be so and don't suppose it will work for all batteries.

Yes, restored many knackered batteries with my smart charger.

Yes, there is something although I can't remember at the mo. It removes the salts somehow. I believe that of a battery is fecked then there is no going back, you can make them seem better for a while until it gets cold and then leaves you in the lurch. We've had batteries in the past that have a shorted cell or something like that and will be fine for a week and then dead as a door nail.
best just to get shot of anything dodgy is my way of thinking now.

I was under the impression that the space between the plates and bottom of battery builds up with crud effectively shorting it between cells which is one of the main reasons battery's don't last (i was also told they can nigh on engineer this space to just the right height to get out of warranty).

Had some success with our CTek charger but it only really brings them back to just about useful again. On the other hand I have a little Chinese charger which positively terrifies me as the battery spits and boils, but the battery appears as good as new when its finished.

If the plates are warped,just bin it. If straight there's some hope

Are there any firms that properly remake tired batteries? I'm guessing it's probably cheaper to buy a brand new battery than to remake an old one to a high standard in the uk?

Could imagine trying to set up a business doing that in the uk? It'd be a clipboard monkeys' wet dream!

Those days are long gone, but with wages and business expenses now could you really strip and rebuild a battery for the cost of a new one.

I wasn't advocating it being done in those working conditions. Just thinking along the Reduce>Reuse>Recycle principal.

I don't disagree that we should look at recycling/reusing etc. Trouble is batteries like many other things are made as cheap as they can be and so aren't easy to take apart. Years back they would be repaired but relatively speaking were probably dearer so repair would be a cost effective option
You got to hand it to the Indians not a pair of goggles or gloves insite

Recycling of lead acid batteries is not only easy to do but you will get paid pretty well to do so at any scrap yard.
£15 quid to cash in your knackered battery seems pretty good to me. No guarantee it becomes a new battery though.

They always say you should reduce the risk as much as possible, and only then opt for the PPE as the last option.
Perhaos the Indians have adopted such a safe working practice that they have reduced the risk to a level that no PPE is required…!
