Is the limit on your battery only a few hours?
New batteries are always shipped in a discharged condition and must be charged before use. We generally recommend an overnight charge. Refer to your user's manual for charging instructions.
New batteries are hard for your camcorder or charger to charge because they have never been fully charged and are therefore unformed. Sometimes your camcorder's charger will stop charging a new battery before it is fully charged. If this happens, simply remove the battery from your device and then re-insert it. The charge cycle should start again. This may happen several times during your first battery charge. Don't worry; it's perfectly normal.
If your battery still does not work well after you try the above steps, you may have a defective battery the manufacturer needs to know about.
Recharge a spent battery as soon as possible after use. While this isn't critical, shallower charges of Li-Ion batteries put less stress on the battery than a deep full charge.
Do not leave the battery in the charger after the indicator says it's fully replenished. (Don't leave the battery in the camcorder either.) Store the battery at room temperature.
Recharge the battery again, just before your next shooting session, to compensate for power slowly lost while the battery was on the shelf.
Unless you're using old NiCds it's not necessary to "condition" a battery by discharging it down to one volt before recharging it. A periodic full discharge is not required for lithium-based batteries and, in fact, a partial re-charge produces less wear than a full charge.
