i need to pick up a simple device that will allow my battery to not die when i am out of town for 10 days or so.
My battery at around the week mark if it doesnt start will die.
i know there are the NOCO and Ctek options but basically i dont have time to do an order, so my options are from local brick and mortor stores, walmart, sears, pepboys autozone etc
I have one of these for my motorcycle. And it was good for my f150 before I figured out that a diode in the alternator had failed and was causing my battery drain.
I leave my vehicles parked for months at a time with no trickle and no jump needed. I have been told that cheapo trickle charges (which I own (2) and do use for my lawn equipment) shorten battery life because they are continuous and do not shut off when a battery is fully charged. This sounds right to me. Something is wrong if you need it for 10 days.
The battery I am using is a interstate megatron800
The biggest version of it. Purchased 4 years ago or so. Maybe the battery has some wear to die so soon. Regardless iv still need to use something.
Are you sure nothing is drawing non-switched power, like an alarm or an amp? I have a couple cars that have this same issue. One is due to an aftermarket alarm. The other...I'm not sure... but I just sold it.
Remove the ground connection from the battery and put a volt meter (>12 volt range) positive on the battery negative lead and negative on the battery negative terminal. The reading you get will be proportional to the parasitic load on the battery. It is very sensitive. Pull fuses until you find the circuit causing the draw.
If you have a DC ammeter, you can use that instead.
thanks all....heading out so for now, just will try the battery tender plus and see what happens...when i get back ill start to figure out the issues in detail
Check all the ends of all battery cables carefully- the ground strap of the engine, the negative battery cable and its connection to the chassis , the starter cable Etc
In addition to that, check wiring around the "moving" parts of the car (i.e. puddle lamps, hood and truck switches, etc). If it's broken or frayed, you'll see it.
