Query: After 10 recharges, batteries don't hold much juice.

I have used this product for over a year, and after about 10 times charging them in the charger, batteries will not last more than 2 weeks even if they are not user at all, if I charge them and use them for a week and take about 20-30 pictures, batteries are then dead.
