12 Volt 5 Amp Hour Rechargeable Battery

Maybe this isn't quite what Sony had in mind for it's adapter. I use a 12 volt dc sealed cell battery, plug a 120 volt converter into that, then convert it back into dc with the Sony adapter. I do that for extreme extended battery use for astrophotography field use. It seems to work fine. There's no overheating in any part of my contraption, including the Sony Adapter.

I love this camera, it’s one of my favourite so far. The fact that under status you can tell you are using the 12 volt SPYPOINT battery is wonderful addition. The only thing left to make it better is to indicate the power left on you 12 volt external battery

This charger not only does 110 but has a 12 volt adapter included.

I was looking for a rechargeable battery to power wireless microphones and these have been terrific. I can typically run two 2 hour productions without needing to recharge them.

Long battery life and high brightness from the output in headlamp. Will go full 12 hour shift in medium brightness

I love how the Charger easily charges the Battery in less than 1 hour. And the Battery life is a mere 9 to 12 hours. Prefect for a whole days production shoot without even thinking of having to recharge. Excellente' !!!

They said to remove the vent cover a half hour before use. I removed the cover and measured about a half volt. An hour later, 1.35 volts. Installed them, and now my vintage Luna Pro works perfectly! Great solution to replace an obsolete part!

Hard to believe a little flashlight like this could put out so much light and for a full hour. And also be rechargeable!

Works as described and supplied my camera for 12 hour shifts.

worked just like the product I replaced except uses a double A battery instead of a nine volt.
