Panasonic K-KJ17MCA4BA Advanced Individual Cell Battery Charger

Steven wants to know what battery charger is best. He's seen one on SharperImage.com that looks pretty good. It's a Universal Battery Charger and it promises to regenerate batteries. Is it legit? Leo says that it's a bad idea to recharge alkaline batteries. He should get a rechargeable NIMH battery charger. Steven can check out theWirecutter.com for the best battery charger. He can get the charger with four batteries for around $21.
