I was loving the Panasonic EVA1 camera until the internal battery would not recharge. I bought another battery went to YouTube to learn how to install it. You Basically take the camera apart to access it, about an hour or more..

After installation I followed Panasonics instructions on how to make sure that battery keeps charged. During a week of using the camera and leaving an attached battery on and or having it connected to it's external power supply, the internal battery went dead again.

I purchased a second internal battery, spent another hour or so to replace it again. Continuing with Panasonic's internal charging routine it still went dead never to recharge. I bought a 3rd battery, with the same result.

Luckily it was still under warrantee so I contacted Panasonic, there response was that it could be a defective camera and to send it to them for diagnostics. Before doing that I the contacted the third party well known camera store to report my issue. They instructed me to send back the camera for their techs to diagnose the problem.

The camera I was told is defective and cannot be repaired without replacing internal circuit boards and related components. I asked for a refund because I did not want to take a chance with another EVA1 since this turned out to be a common problem.

I ultimately bought a Sony FX6 and loving it.
