The plates should be covered. From above plates look like narrow pale bars. Rock the battery gently to see the fluid level. Add distilled water if needed.
Yes, A car battery can have enough charge to turn on car electrical components but not start the car. This is not much of an indication of a bad battery however. Use a volt meter to test the power in the battery. If the battery seems low put it on a trickle charge. Most modern chargers will tell you if your battery is bad or not. The battery also has to be load tested to determine if it's good or not.
The fluid in a battery, sulfuric acid and water, has a ph around 1.
What is the car? Autoparts store can usually tell you just tell them ur car when you go to buy the fluid and they can tell u what type and how much
Yes, that is how you know that the battery is "strong" enough to start your car in cold weather. A battery in warm weather may have enough amps to start the car fine, but in cold weather, it wouldn't be able to crank it fast enough. A car battery efficiency drops off the colder it gets.
Car battery charges can check the damage done to the actual battery but to the entire car is another story
Not with out being attached to a battery charger. On a 10 amp charger in 8 hours it will charge enough to start the car, allowing the battery is god enough to charge
If your leads are long enough, yes.
Regular checks to make sure that there is enough DISTILLED water in each of the cells is the best preventative maintenance - should be done at least monthly. Do not remove the fluid from a battery - you could get severely burned by the chemicals inside. Changing the battery fluid will not prolong the life of it either. Figure on replacing the battery every two to 4 years, depending on the climate in your region.
take the car to a repair shop and have them put a battery tester on it. it may be the alternator or the battery the tester will tell
A fully charged cell in a car battery produces 2.2 volts, there are 6 cells in a battery. That would make true open circuit voltage on a fully charged battery at 13.2 volts. So a 12 volt open circuit reading is a discharged battery. The battery can have enough chemical reaction to produce voltage but not enough potential or power to crank the engine. Think about a fresh 9 volt battery. It is big enough to produce 9 volts, but not enough to crank a car or even light the dome light dimly. A car battery wears out slowly from the time it is purchased. Eventually it doesn't have enough power or amperage left to operate the car.
You can tell a car's battery type by contacting a store that sells car batteries. You will need to give them the make and model of the car. They will let you know.
what is your question.... which battery is needed on your lexus...? Go to an auto parts place and tell them the model car you have or remove the battery and bring it to them... tell them you want the same...
