DESC: Running out of battery power before you're done taking pictures can put a damper on your next big event, not to mention the memories you miss. This Lithium-Ion battery gives you an peace of mind when you're out shooting with your Panasonic DMC-FZ30. Since it's composed of Lithium-Ion, there is no "memory effect" to worry about. Unlike more common Nickel Cadmium batteries, Lithium-Ion batteries can be partially discharged and recharged (fully or partially) without damaging the battery. Besides the added convenience, this also greatly extends the life of your battery.
