FOAK: Battery reviver additives

I'm know this has been done to death, but can I find it? No.

I've a relatively new but tired battery that won't take a charge due to
infrequent use of the SVOC and suspect it's clogged up - there was a
chemical that can be added to 'unclog' - I'd be very grateful for the info
as a new one is well over a hundred quid . . . . .

The pills Halfords sell have been recommended in the past, if that's
any help.

EDTA. To do it properly, you need to drain the battery, wash out the
crap from the cells and refill it with electrolyte before adding EDTA.
Follow up with a long slow regulated charge - about 0.5 amp for a week.

If you want a quick and dirty fix...
You can revive a partly sulphated one with some EDTA (bout 1/2 tsp per
cell) and try it.

 

Cheers - That's the one I was after.

 

Ta - I'll check it out - see they contain any of that there EDTA which
comes highly recommended

 

In uk.rec.motorcycles, Buzby belched forth and ejected the following:

Batt-Aid is the stuff you want.

 

Just be aware that most batteries have come with EDTA added already
for quite a few years. I think the best procedure would probably be to
put as much charge into the battery as possible (to get the plates in a good
oxidation state) then drain, rinse with distilled, fill with new electrolyte
and the recommended amount of EDTA, then put on trickle charge for a while.
