I have been looking for a battery for my Clie which doesn't light up. I saw many websites selling 3.7Volts, 750mA battery. I also ran across the following listing for 3.7Volts, 900mA battery on eBay. Will it work fine with T615C model? The online ad says it will work for T615 model. Is there T615 model(without C) which is different? Please let me know if the following will work for T615C clie.
