I have only used the camcorder with the battery for a short period of time. I am looking forward to using it for extended periods of time over the holidays and will know better then. I can say that it seems to have charged just fine, but again will be interested to see how long it lasts. I would like to say that I was very pleased with how easy it was to order from you and how quickly I received the battery after I ordered it. Thank you for that! One suggestion: When shipping, the battery it could use a stronger, sturdier box. When I received the battery, it had been "beaten" by the shipping and was no longer in the small battery box or the plastic wrapping. It does not appear to have damaged the battery, as far as I can tell. Thank you for soliciting my feedback! I would definitely order from you again :)
