I just bought a Sony HDR-XR 160E camera. Is it normal for Sony original battery not to be charged?

There should be virtual electricity. Empty electricity means that the product has been discharged for a period of time after leaving the factory. In fact, you have to test the machine when you buy it. If the battery is left empty for a long time, it may be fatal to the lithium battery. Now you are very passive in finding a business, and you can't prove that it is empty electricity. However, you should go to him. If the seller is polite, he will let you Wally put it in the depths to test it. If the battery is dead, he will. Try to find your local Sony service again. If you can't find your local 3 15, you can't go to court again ... it depends on whether you have energy, enough time and good luck. It is really fruitless, so it is a lesson. Three-charging and three-charging are only suitable for Ni-MH batteries with memory, but this method is invalid for lithium batteries.

Your supplementary question-NP-FV50 battery is officially standard, and many sellers only change it to NP-FV70 battery when they match the packaging.
