Just got my battery replaced with a Rayovac battery at Batteries Plus. They showed me the business card of the guy they get the batteries from; I guess it could vary, but at the location I was at they're made by East Penn and they just slap the Rayovac sticker on it.

If yo uare tired of paying the high prices for batteries you may be wondering which companies sell rechargeable batteries. Rayovac, Duracell, and Energizer all sell rechargeable batteries.
They are manufactured by Deka/East Penn Battery in the USA under license from Spectrum Brands of Madison, Wisconsin. They are distributed by Batteries Plus.
If you need 4 AA batteries, buy the Duracell. If you only need two, buy the Ray-o-Vac, it's cheaper.
I would suggest carefully reading all the instructions that came with your specific charger for a correct answer to this. Some Rayovac chargers are designed for one and only one battery chemistry, while others can handle different chemistries as long as all batteries in the charger at one time are the same chemistry and yet others actually allow mixed chemistries at the same time.
