Query: hand set Battery doesnot last long

The product was good for first 3 months later the battery in hand set started loosing power, even charged over night it lasts for 15 min or less,panasonic customer service sucks, they are not replacing the battery, the product comes with one year warranty still they are not helping to replace the product.I'm never going to buy any panasonuc products.
