Gel batteries for vehicles are not inteded to be left for an extended period of time without at least a tricle charge. The best way to see if it is still any good is to put it on a charger that produces 1/1000th of the batteries amp rating and leave it there for 48 hours. this extremely slow charge will keep the battery from exploding and can re-excite the battery's chemical reaction.
Clean the battery up with baking soda and water then fully charge it. Store it in a cool dry location. Recharge the battery every 2 months.
Depends on the condition of the battery. Most will hold a charge for at least 6 months if they are not connected to anything.
If a car sits for that long it is usually necessary to recharge the battery before you will be able to start it.
No, this is a myth, storing the battery on concrete will not effect it any more than storing it on any other surface. The battery case does not conduct electricity. Fully charge the battery and store it in a cool, dry, low humidity, location. The cooler the better as long as it is above 32 degrees fahrenheit. Recharge the battery every 2 months.
The most common reason for a vehicle not to turn over is a bad alternator. If the alternator is not charging the battery the engine will not start, regardless of the battery age.
I am still using the same car battery for 8 years 4 months and it is fine , but I've had a battery develop a dead cell at 3 years 10 months ( the battery had a 4 year free replacement period ) Know that every time you run the battery down, you take months away from the life of the battery. Many things contribute to the life of a battery. Short trips of less than 20 minutes will shorten the life as the alternator will not fully recharge the battery. Extreme temperatures either hot or cold shorten the life of a battery. On average a battery will last from 36 to 48 months. But I have had them last 7 years and others that only lasted 3 years.
I've had to replace batterys at : 3 years 10 months - because of a dead cell ( had a 4 year free replacement warranty ) 6 years 6 months - because of a dead cell ( the original battery in my Ford Explorer ) 8 years - was getting weak when temperature was colder ( original in my Volvo ) The replacement Ford battery in my 1995 Ford Explorer is now 7 years and 4 months of age and is still working fine , but that's not to say that today I drive somewhere then go to leave and my vehicle won't crank or start if the battery has a dead cell condition that requires me to get a boost to start the vehicle . A vehicle that has a battery with a dead cell can be boosted to get it to start , but if the vehicle is shut off it will not start again without a boost or putting it on a battery charger
It will naturally lose some of its power, but should still be hot enough to start the vehicle if it's a good battery, and was fully charged when stored.
Yes, but much more slowly than when the cable remains connected. Batteries lose power as they age. Attached cables, even when the circuit is open, accelerates this process. This is why if you do not intend to drive a vehicle for more than three months you should detach the battery cable. Even then, after multiple years in storage, you may have trouble starting the car without first charging the battery.
Nothing you have to do. It will be fine sitting for 1 month. If you plan on storing it for 3 or more months then put a trickle charger on it and leave it connected.
According to Amazon - you get about a months usage from a single charge.
The vehicle's ECM (Electronic Control Module) performs a self diagnostic and resets itself automatically when the battery cables are reconnected. It does this same routine each and every time the negative cable is removed from the battery prior to doing any electrical work on the vehicle. Just put in a new battery, attach the cables and you're good to go.
