Long Life Battery

[edconline]

I wasn't sure about putting this topic here or in the engine section, but I think this is more appropriate.

I'm thinking about replacing my stock battery with something that holds a charge a lot longer. I have a Lukas LK7900 dash camera, with a huge memory, and I have the LK290 module so that I can leave it in parking mode while I have to leave it somewhere. However, this module will cut off power to the Lukas when battery voltage drops below 11.8V. This can happen in as little as 3 hours when the car is parked and the camera is constantly detection motion and recording clips (like in a shop for instance). Several times, this has resulted in my missing sections of video I would have liked to have.

Ideally this replacement battery would hold a charge for days while parked, even if the camera was constantly recording. (I don't know the exact current draw of the Lukas offhand, but it can't be much) Even more ideally, it would be the same weight or lighter than the stock battery.

What are people running for aftermarket batteries with extremely long life? I used to use an Optima Yellow Top years ago in a car with a big audio system in it, are those still 'the standard' in power holding? IIRC it was pretty heavy..

Any input is welcome!
