MAXX CAR BATTERY INDICATOR CODE

TOP TIP: Before you disconnect your battery make sure you know the code for your stereo – otherwise you may find it won't work when you reconnect it! How do I test a car battery for dead cells? If the battery holds a charge when it's not connected to the car, it's not faulty. Then, fully charge the battery, leave it for 12 hours and test it.

Apart from doing the obvious (setting your phone to record video before you place it in the boot or glovebox to see if the bulb is staying on), you can either remove the leads from the battery, or remove it from the car entirely. This is where something electrical - a light or a motor for example - is draining the battery, even with the engine turned off. If the battery is continually going flat, it could be because of a 'parasitic loss'. What do I do if the car battery is repeatedly going flat? Bear in mind that when a battery goes down to 12.2V it's actually only 50% charged, and below 12V it's classed as discharged. The resting voltage should ideally be no lower than 12.6V. If you're getting a reading with a minus in front of it (-12.6 rather than 12.6) you've got the probes the wrong way round. The terminals will be marked '+' and '-'. Hold the red probe to the positive terminal and the black probe to the negative terminal. This will allow you to accurately measure 0-20 volts. Using your multimeter, you want to measure DC voltage (this is indicated with a solid line and a dashed line above a letter V). Once the car battery is exposed be careful that nothing metal touches the terminals, so don't rest any spanners or other tools on it.

Haynes manuals show you where to find your battery and make the job of replacing it easy by guiding you step-by-step.

There may also be a cover over the positive (+) terminal, which usually lifts off. The first thing to do is make sure you can access the two terminals on the top of the car battery.Ĭar batteries are commonly located in the engine bay to one side of the engine, and often have a plastic cover which will unclip, lift off, or occasionally require the removal of a couple of bolts. Testing a car battery with a multimeter is a simple process. How do I use a multimeter to test a car battery?

Keep the charge level as high as possible, do not expose the battery (and the car in general) to extreme temperatures, clean and care for the surface and filling of the battery, and watch for the constant alternating voltage coming from the car. All this is explained by the fact that in pure form lead does not possess reliable physical and chemical properties. Usually electrodes are made from alloys of various metals (antimony, calcium, etc.). At the cathode, it is ordinary sponge lead (Pb), at the anode, lead dioxide (PbO2) acts as the active mass.Įlectrode grating plates in the form of pure lead are rare. Note that the electrodes are manufactured in a lattice structure, and it is into these pores that the active mass is pressed. Inside the battery there are two electrodes – negative (cathode) and positive (anode), on which the so-called active mass is located. This type of battery is a combination of lead plates (electrodes) and electrolyte material made from a solution of sulfuric acid (H2SO4).

The range of batteries is presented in 4 types:
