I was in my local Target during lunch and saw on clearance Kodak "PRE-CHARGED" AA rechargeable NiMH batteries (set of 4) for $5. These are listed at 2100mAh. The blister pack says "Stays Charged 4X Longer than ordinary Ni-MH..." which I assume it means these are the newer low self discharge type (Sanyo Eneloops, Rayovac Hybrids, etc.). No idea how long they have been on the shelf but I took a pair straight from the pack and put into my wireless mouse. Functioned perfectly without precharging. I have used the Rayovac Hybrids in other devices and highly recommend them. Don't know if this is local or a national clearance so may be a YMMV. SKU is 057060235.
