Default Disappointing Ray-O-Vac

While trotting through K-Mart the other day, I picked up 4 AA 1600mAH Ray-O-Vac NiMH batteries for about $12.

I put them in my wireless mouse to try them out. Powerex 1600mAH from Thomas run the mouse for months.

Unfortunately, these Ray-O-Vac batteries completely washed out from a full charge in only about 3 weeks.

Pretty disappointing performance and not a good investment, considering that for a couple of bucks more in total cost with shipping I could have bought the Powerex brand.

I saw a post here a while back talking about the same Ray-O-Vac batteries and wonder what others' experience has been with these.

I've heard reports that new Nimh batts in cams don't do well on the first couple of charges. After the've been emptied a couple of times and re-charged they are often OK.

I agree, when I first got my Sanyo VPC-X350 the Sanyo batteries did not work good for the first few charge/discharge cycles.
they held a charge longer after being cycled a few times.

You will always need to cycle new NiMH batteries 3-4 times before they will hold close to a full charge. This is because most chargers cutoff before a "full" charge to avoid damaging the cell. The fullest charge you will get is about 90% so it takes 3-4 charge/discharge cycles to condition a new cell.
