I have a 92 Pontiac and also had similar situation. Sometimes the voltmeter would go to 14volts and other times it would sit at 12volts. When I tested output from alternator to the battery with voltmeter, I did not get a good reading. Upon removal of the alternator to get it replaced, I noticed that the smaller (red) cable that goes from the alternator to the battery was loose in the connector itself. I cut the cable at the connector, stripped the cable some and crimped on a new connector. Reattached to alternator and put alternator back into vehicle. All has been fine since. Hope this may fix your problem.
No. A battery that will not take a charge has a dead cell. It cannot be repaired and must be replaced.
If the battery is not taking a charge it is bad and needs to be replaced.
A battery that won't hold a charge has a dead cell and must be replaced. This is assuming there is not something on that is pulling power from the battery.
If you replaced the battery with a brand new one, then no. The battery comes from the store with a fuul charge. If it didn't come charged up, then you have bought a defective battery.
If it has a dead cell the battery will not hold a charge and must be replaced.
Loose or corroded connections or the battery has a dead cell and will not accept a charge and must be replaced.
Yes I can it will charge slower until it get about 5% charge
Charge and load test battery- it may be not able to take a charge and need to be replaced You may a have blown fuseable link preventing alternator from charging battery
Because it has to be replaced.
Then either something is on draining the battery or the battery has a dead cell draining all the rest and must be replaced.
Replace it when it will no longer take or hold a charge.
You probably have a bad battery. You probably have a bad battery.
Yes, it will take slightly longer to charge, but it will last a bit more once charged.
It means that your device's battery is dead. It's a warning that the battery MUST be replaced!
Try changing the battery.
Inside the alternator
maybe is time for you to get your battery replaced
It will need to be recharged and if it will not accept a charge it will need to be replaced.
Voltage regulator or loose wire.
30 year old battery?? I have never heard of a battery lasting this long. This has to be a record of some sort. I would contact the battery manufacture as they may want this battery and give you a new one for it. Anyway if the battery will not hold a charge it has a dead cell and needs to be replaced.
Some new alternators will not charge unless the battery has a full charge already.
This particular battery is advertised as being very long-lived. If you are having problems getting it to hold a charge, it may be faulty and need to be replaced.
Generally, no. If you ran the car after the alternator died (which runs down the battery), you may need to trickle-charge the battery for a half-hour or so to bring it back up to a full charge, but most of the time the battery will not need to be replaced.
There are normally two reasons a battery will not hold a charge. First off, the battery may have a dead cell which means the battery must be replaced. Secondly, something may be on pulling power from the battery. This can be a light, or a relay that is stuck.
The battery light coming on in your Town and Country minivan means that the alternator needs to be replaced. The alternator charges the battery and if it goes bad it will not charge the battery.
