Most camper type vehicles have 2 batteries, one for vehicle operation and the other for appliance operation.
The appliance battery should be "isolated" from the other, meaning that it should only charge when the engine is running and should not draw power from the other battery. Battery isolation circuits are available at most RV supply stores.
The key being in the "on" position itself. As for rapid battery drain, you could have a bad battery or there could be a loose connector. Source: Personal experience
Yes
Radio Use when engine is not runningYes, use of the radio when the engine is not running will drain the battery. Also, IF the use of the radio requires the ignition switch to be in the ON position, then any other devices [such as on-board computers, electric fuel pumps, etc.] that are turned on when the key is on will also add drain to the battery.IF your vehicle ignition switch has an "accessory" position [usually one "click" counterclockwise from the OFF position, then only the accessories that you turn on, will drain the battery.
YES!My version:A bad relay switch that goes bad can "stick" in the on position and leave what ever it powers on and drain the battery You should be able to see the item that is on.
Either the switch was left in the wrong position, or the thing is defective. The dome lights draw enough current to drain the battery overnight.
No, a bad coil will not drain the battery.
Dead cell in the battery requiring a new battery. A light that is on pulling power from the battery. Relay stuck in the closed position. More than likely the battery has a dead cell.
Yes you sure can. It is a myth that sitting a battery on concrete will drain the battery. It will not drain it at all.
Actually doing ANYTHING on your ipod touch whether it be listening to music, or pressing some buttons will drain the ipod battery. some things drain less battery then other things, but they all drain battery. (for example, listening to music does not drain as much battery as watching a video.) I do not know any buttons on the ipod touch called the hold button, but if you are talking about the button in the front with a square on it, that does not drain battery. if you keep holding it, a whole lot of options might open, but it does not drain battery. If it DOES drain battery, its so small of a drain that you won't notice it and it won't impact your ipod's performance
If the ashtray light is not working it will not drain the battery.
Bad battery or a parasitic drain
School does drain your battery because the satellite connection in school has been made to drain your battery in cell phones and any type of electronic device.
