[QUOTE="DidUHearThat?, post: 4927917, member: 594758"] If you plan on doing this often, you need to do as helotaxi suggested. I have installed a second isolated deep cylce battery because I like to use my system and other electronics for extended periods with the engine off. It's hard to calculate your time exatcly, but my best guess is your already in a danger zone running your laptop/inverter/radio for even 1 hour with the engine off. The battery is new and strong, but it wont' stay that way with this abuse. It's not designed for this. You need a second deep cycle battery. Also your charging time needs to be GREATER than your draw time. 1 hour off needs to be matched with at least one hour with the engine on. 5 - 15 minutes of charging time is just not enough to bring your voltage back up. You can install a voltage monitor to help you watch for voltage drops. When the voltage starts to drop, it will drop fast and keep going faster and faster. Called the sudden death syndrome. [/QUOTE]
