Alkaline Rechargeable Batteries?

[Doggiedog]

I was buying some rechargeables this weekend when I came across some AAs that were rated 1.5V vs 1.2V that you usually see. I was almost about to buy them when I noticed they were rechargeable Alkaline. WTH? Are they just like normal Alkaline batteries? Am I missing something here?

Alkaline rechargeable batteries exist. Only differences with 'regular' rechargeable batteries include:
- they can only be recharged about 100 times
- they require a special charger.

Often or always they don't need to be fully run down like nicad rechargables do. You can recharge these at any time to top them off. Of course they won't have the life of a brand new top of the line alkaline...I am not sure how powerful the really expensive recharables are tho.

I use rechargeable akalines in my Mag-Lites. It is a lot cheaper since a regular battery goes dead waiting for you to use the light and then has to be trashed.

They were about 30% cheaper than regular NiMH batteries but if I need to buy a special charger for them, I guess I'll just pass.

Thanks.

I use Rayovac brand because for $20 they have a charger that will do NiCad, NiMH or alkaline battries. You can't mix the alkalines with any other kind but it is no big deal.

I use Rayovac renewalls and love them. They last longer and are more powerfull than nimh or nicd batteries. The only drawback is, they can't be recharged more than 15 or 20 times, but they don't cost much more than normal alkaline batteries anyway, so you save a considerable amount, and less poison for the enviroment...double bonus 🙂
