konstantin smola Posted December 28, 2009 Share Posted December 28, 2009 Hi, Today I got my Arri SR2 HS. I tried to charge the batteries, and have a question about the charger. I found out that I can plug one of the battery-cables in the charging unit, and then both LEDs light up. But what is this good for? Thanks!

Premium Member Tim Carroll Posted December 29, 2009 Premium Member Share Posted December 29, 2009 Today I got my Arri SR2 HS. Konstantin, Congratulations on your new camera. It's been years since I used one of those ARRI chargers, but if memory serves, you plug one charger cable into the center socket when you are only charging one battery (instead of two). I don't remember if it then charges the one battery faster, or you do it so the charger doesn't get damaged by only loading one charger cable. Sorry I don't remember it more clearly. Best, -Tim Link to comment Share on other sites More sharing options...

Best, -Tim Thanks! I tried to charge the batteries, and it seemed to work correctly. But when I let the charger cool down again (unplug and wait a few minutes) I can charge the batteries again - Plug everything in, both LEDs light up and the Batteries get warm. After a few hours the LEDs go off. I could repeat that a dozen times. But when are the Batteries fully charged? Thanks! Link to comment Share on other sites More sharing options...
Premium Member Tim Carroll Posted January 2, 2010 Premium Member Share Posted January 2, 2010 Again, I'm a little fuzzy on this, but if memory serves, the charger has a built in timer. It is not like some of the latest chargers which sense the battery's charge and adjust accordingly. IIRC the timer starts a charging cycle when you plug the charger into the wall and the battery into the charger. It charges for a set period of time, then shuts off, regardless of what charge the battery has. Get yourself a volt meter to check the charge on the batteries. When they get low, run a charging cycle with the charger. I used to run a charging cycle with my SR batteries once a month when the camera was not in use, and more frequently when the camera was being used.

Premium Member Dom Jaeger Posted May 19, 2010 Premium Member Share Posted May 19, 2010 Tim is correct, the charger has a timer. Unplugging the unit for 15 seconds or so resets it. By plugging one lead into the centre socket the unit switches to a fast charge cycle. Link to comment Share on other sites More sharing options...
