Replace your Sony Handycam camcorder battery and don't stress about the cost of a brand new one from the manufacturer. Lithium-Ion batteries really only last about 200 full charges, so there is a breaking point after a few years when the battery simply refuses to hold a charge anymore. You can't scold or verbally abuse your battery in an attempt to change its mind and start holding a charge again - it merely can't do it anymore and you would look pretty silly.
Getting a third-party manufactured battery saves you the money of a name brand product, but still offers the same quality. This battery is designed to replace a Sony Handcam camcorder battery with the part number NP-F770.
