Sony Rechargeable Batteries Last – and Talk Back

This isn't a feature most people consider much, but the Sony digital camera battery is worthy of mention. Called a “High-Stamina InfoLithium® Rechargeable Battery,” these batteries are amongst the best on the market, outlasting nearly all the competition in almost every camera category. Of particular note is the new battery for the Cybershot DCS-T30, which allows the ultra-compact to take up to 420 shots on a single charge. Another great feature of Sony's InfoLithium batteries is that they tell you how many minutes of operation are left before they need recharging.
