Should I use the same brand as the battery charger?

I will buy a battery charger. Rayovac I like it: I http://www.beegool.com/product_info.php?products_id=21737 Can not find the Rayovac Alkaline AAA rechargeable batteries to go with it, however. I found, for example batteries: http://www.amazon.com/Juice-Rechargeable-Alkaline-Batteries-Packages/dp/B000FKGETQ/sr=1-2/qid=1161728405/ref=sr_1_2/002- 5569982 -5956049? ie = UTF8 & s = HPC But he said: "Only load with rechargeable alkaline battery charger JUICE." And all the other cells have a similar warning. Is this a real warning, or are trying to make sure I buy everything in your company? Oh, and I especially alkaline, as suggestions for other types will not help me. Thanks!

You should be able to use any type of rechargeable alkaline batteries. The company said that you only buy your brand.
