Identify potential issues by tracking voltage over time and get alerts whenever a battery check is recommended. Monitor your car battery health and avoid the hassle of a drained battery. This data and the way it relates to the design of your battery should provide you with some useful insight into the functioning capacity of your car battery.ĬAR BATTERY HEALTH MONITOR BY ZUS SMART DRIVING ASSISTANT APP However, to remove this issue, Sealed batteries come with materials to fix the electrolyte setup. Whereas, in conventional batteries, the fluid could evaporate, which results in less fluid level and makes it dead.
#MAINTENANCE FREE CAR BATTERY INDICATOR FREE#
If the battery isn’t fully charged, it will diminish to 12.4V at 75%, 12V when it’s only operating at 25%, and down to 11.9V when it’s completely discharged. A maintenance free battery is a product that is not intended to be opened or refilled again. With the engine off, you should get a reading of 12.6 volts. The ideal car battery voltage range will provide you with a relevant interval according to which you can measure precisely what the voltage says about the battery’s current charge.Ī perfect voltage with the engine running is between 13.7 and 14.7V. Measuring your car battery’s voltage can be a great way to determine how charged your battery might be. WHAT IS THE IDEAL CAR BATTERY VOLTAGE YOU CAN HAVE?
It is the same with the starter motor, which is built to sustain frequent starts without overheating. The alternator is designed to cope with frequent starting and, hence, charges the battery more rapidly.

Battery charge indicator on the top of the battery shows green which should indicate full charge, but still there is no power to the electrics (i just get a very faint battery light. Such cars have more efficient alternators, heavy-duty starter motors, and specially designed batteries. My 75 1.8 (petrol) wouldnt start (and no power to any of electrics) so I took out the battery and charged it. These days, many cars come with stop-start systems, which demand more electrical energy. If you seldom open your car’s bonnet, then the best advice is to replace your car’s battery every year, but that does not mean car batteries have a lifespan of only 12 months. Try to replace your car’s battery with a maintenance-free battery that has an indicator showing its state of charge, so that you can be aware of its health. If it doesn't - replace it.G enerally, car batteries should last at least one year, although neither car manufacturers nor battery-makers ever declare a battery’s lifespan. If the battery performs well, leave it alone. In short, don't worry abouth the battery eye. One cannot deduce a state of charge of a lead-acid battery by its open circuit voltage, other than to distinguish between completely depleted and somewhat charged. Less than 12.0V - battery depleted or badġ2.1.13.0 - battery MAYBE in some state of charge other than completely depleted.Ībove 13.1V - battery in some rare failure mode with voltage above normal, no good behavior expected. The voltage of the battery (with no engine running) is pointless as well. in older battery) may be in another state. Whatever the indicator shows, it is immersed in one cell, others (esp. The level somewhat depends on the temperature, a hot battery may have somewhat higher level. A fully charged battery turn green only when shaked.
The green color may be a matter of mixing the electrolyte. A simple voltmeter or multi-meter can also be.
May need topping up with deionized water (but the battery is likely marketed as maintenance-free and hard to open, so no topping up possible). Green indicates a healthy battery, Black or Clear indicates your battery may need charging or servicing.
White (red on some brands): electrolyte is low. Green: electrolyte is dense enough (battery charged above some point) and high enough level.īlack (white on some brands): electrolyte is watered down (battery somewhat depleted) and still high enough level. The only reason it exists is that is increases sales of new batteries.
