Battery charger or Battery Maintainer

    My truck has a draw somewhere. I don't know if it's a bad ground or what but when the truck sits for more then a day the battery dies. What can I use for the battery to maintain a charge so I don't have to call AAA everytime I need to go somewhere.

    not trying to be a jerk, but find the draw... a battery maintainer is a bandaid on a cut that needs stitches...

    drawing the battery down to the point where it wont start in just one day is very significant.

    How do I find the draw? I have had problems since I bought the truck. The stealership that sold me the truck went out of business.

    What you can do in the mean time until you get it fixed is to buy a swan connector and put it on the battery post.

    basically gives you a switch to cut the current when your not using it.

    disconnect negative battery terminal, put multimeter in series between terminal and lug. set meter to amps. be sure door is closed and no accesories are on. what is the reading? if it reads anything close to 1 amp, you have a draw somewhere. start pulling fuses 1 by 1. when you see the amps drop, then you found the affected circuit.

    Yes. But you get what you pay for
    A test light will also work. But not as accurate.

    Based on your questions, I'd recommend taking the vehicle to a qualified tech for repair. Not trying to be an arse, but I'm thinking this is above your technical ability.

    I've used a test light most of the time.

    The old style tube automotive bulbs work good too. They require less amps than a test light to light up. Most cases a test light is enough.

    Find the draw would be the main concern

    I love it when I can learn something new:
    <http://www.dpciwholesale.com/Swan-Type-Battery-Terminal.html>
    <http://www.walmart.com/ip/Everstart-936W-Everstart-SWAN-Terminal-Disconnect/16006670>
    And for those of us stuck with side-post batteries: <http://www.amazon.com/Side-Battery-Master-Disconnect-Switch/dp/B001N72FES>

    Thanks for that info! Thanks to Linckeil, too. :salute:
    I have some suspects for where the "juice" in my battery might be sneaking off to, but I need to narrow it down. I might be breaking out the DMM tomorrow, and doing some troubleshooting.

    It's a temporary fix until you can narrow it down. And a cheap one over all. Especially if you don't have a warm shop and are waiting for a good day to tackle a draw issue.

    The only draw back is that all your equipment will re-set with the disconnection, but, it's probably no different than draining your battery and having to jump start it.

    ^^^ More good stuff. I wondered how he checked both volts and amps without changing the current path. That's a Midtronics PBT-100 tester he's using; around $115 on Amazon. Seems like a good investment.
    The PBT-200 is about $60 more on Amazon, but can show CCA.

    Does anyone here use a ZTS LA-2 tester? I have a lot of 6V sealed lead-acid batteries, and the LA-2 will work down to 2 volts, where the Midtronics only covers 8-17 volts. The ZTS is more expensive, and doesn't have a digital readout; it just shows AH, as 1-4A, 5-15, 16-50, or 51-200AH.
    How good would that be for automotive stuff?

    Thanks. Back to topic. :nod:
