Canon BP-970G Battery Pack for C300/C100

Take advantage of uninterrupted power with this rechargeable Lithium-ion battery. Lithium-ion batteries last longer and are resistant to the effects of "memory effect", meaning you can charge and recharge your battery without fear of draining the battery. This lithium-ion design ensures long life between charges with a manufacturer estimated battery life of 7.2 hours. Of course times vary depending on camcorder and shooting conditions. In general you can expect 4-5 hours of C100/C300 operation from a fully charged battery.
