They have a habit of not being exactly high quality and you won't get a multi-step profile. So in either case one of those CV/CC Amazon Chinese buck/boost regulators might be fine, in theory. Strictly speaking a resistor and a fuse would be all you'd need.įor a gel you'd need to buck the voltage down, they can't tolerate the relatively high voltage of flooded/AGM. If it's not a gel type your vehicle already has a charging system that you could almost just plug it into the cigarette lighter but you'd want to current limit, both to safely charge and to prevent melting the outlet. Is the battery a gel (like for a UPS or something) or a maintenance-free SLA/AGM type?

If you prefer to have a professional test your battery, give the team at YourMechanic a call.You're not crazy. So, next your car won’t start and you suspect a dead battery, whip out your multimeter and get to work.
That’s it! Testing a battery is relatively simply, inexpensive and leaves you with a sense of empowerment. With an electronic tester: This test sends a frequency wave through the battery to determine the condition of the cells inside.
If the voltage drops below 9.6 volts during the test, it is bad and should be replaced. With a load tester: This test applies a load to the battery while the tester monitors the battery voltage. There are two methods for fully testing a battery: Most auto parts stores will do this for free. Once the battery is fully charged, it can be tested to determine whether it is good or bad. You can also remove your battery and have it charged at the auto parts store. Then, drive the vehicle for 20 minutes or so at speeds greater than 40 mph. If you decide on the second option, you will need to jump your battery first.

This can be done with a portable battery charger, or by charging your battery with the alternator. If your battery has a low state of charge, the next step it to recharge it and test it further. A good battery is one that will hold a charge. A battery that has a low state of charge may still be good after it is recharged. It only indicates the current state of charge. Note: A state of charge test does not indicate whether your battery is good or bad.Anything below that should be recharged and tested with professional test equipment. If your battery is greater than 12.45 volts it is sufficiently charged. 01 volts for every 10 degree change in temperature. These readings are for a battery at 80 degrees Fahrenheit. Check the voltage reading on your screen. This is not the setting you want, unless you plan on testing household appliances. The DC reading with the squiggly thing (sine wave in technical terms) is AC voltage. This is the DC reading with the line above it. This is just a gentle reminder that the red goes to red and black goes to black. No need to panic if you get the leads backwards you’ll just see a negative reading instead of a positive one. Touch the black multimeter lead to the negative battery cable and the red lead to the positive battery cable. Turn the vehicle’s lights and ignition off, and have your materials ready.
#Auxl car battery manual
If you can’t find your battery, consult your owner’s manual or do a quick search on your car model to reveal the location. They could be in the trunk, under the back seat - and some are even mounted in the wheel well! However, some manufacturers like to hide the battery in obscure places. Most batteries are under the hood near the fender. In order to safely and efficiently test your battery, you need a couple of basic tools. This test will reveal whether or not your battery is fully charged. Fortunately, you can check the state of charge of your battery using an inexpensive multimeter. You think the battery is your problem but you’re not sure. You go to start your car and all you hear is a clicking sound.
It never fails - you’re in a rush and the kids are throwing a tantrum in the backseat.
