Pens N' More via eBay offers the Rayovac Platinum NiMH Rechargeable Battery 4-Pack in AA (pictured), model no. PL7154, or AAA, model no. PL7244, for $7.99 with free shipping ($2/battery). (TNT Deals via Amazon charges the same price for the AA with orders of $25 or more.) That's tied with our mention from last week and the lowest total price we could find now for either pack by $4. These batteries can purportedly be charged up to 300 times.

Of note, add five 4-packs to your cart for an in-cart price of $31.95 with free shipping ($6.39/pack), yielding another price low.
