Reviving NiMH batteries.

[Maggot4x4]

I have some NiMH AA's that have only about 25 recharges on them but now don't want to hold a charge properly.

What is the best way to cycle them to try to bring them back to life?

<span style="color:blue">have you tried zapping them like you do with ni-cads...?

i have no idea otherwise.....


this might be something drivesafe might have a bit of knowledge on....</span>

How old are they? A couple of years ago I bought new in the pack batteries for a couple of mobile phones and found them both to be stuffed. Old old stock, after a couple of years they lose their zing.

Hi Maggot4x4, first off how old are they and how much use have you got out them.

I do exactly what Zook recommended with Ni-Cads and that can some times extend their life a bit but I have never tried it with NiMH and I would suggest some caution because both types are prone to blowing up if handled incorrectly.

Cheers

freezer???

Whatever you do... be carefull.. these things can go off like firecrackers if you fry them https://www.aulro.com/afvb/

Chuck 'em away. Go to Jaycar, get some new ones, cost almost nothing.
