Default Battery Refresher

Been out of racing for some time.
I'm getting my 1/12 scale stuff ready for some long awaited racing.
My Question is............ My batteries have sat around for 1.5 years now. I have 3300's that were top notch packs back in the day. How should I get them back in condition?

I have a GFX 35 charger
Should I Zap them at 6V then discharge them at 30amps until they charge correctly?

What should I set my Detect V drop to .04?

I have discharge trays .etc

I would like to hear your guys advice

Not worried about racing level. My question is what is the best way to rejuvenate your batteries after thay have sat for a more than a year dead shorted.

it might be hard to get them to take a charge.

You should probably set your peak detect very high, and charge at a low amp rate, like 2-3 amps for at least a half charge. Then you will probably need to cycle them a few times, like you would normally do. Charge at 6, and discharge at 30. Let rest and repeat.

The Spintec Battery manager will get your batteries back into shape.

I've tried it on old NiCd packs (1700's and 2000's) and after a few cycles they were pretty good again.

More important, it will keep your new (future) packs in good shape.
