How long does it take to recharge a dead battery

Most charger systems for recharging batteries will not recharge a dead battery. But you may be able to bring the battery back to a voltage high enough to get the charger to work. Find a battery drill with the same voltage. Take small alligator clips and hook the battery up positive to positive, negative to negative to your same voltage dead battery. Leave it several hours till the voltage grows in your dead battery. Then try the recharger that came with the bike battery. Don’t leave the batteries inside while you are doing this.

if the battery goes dead or low it must be recharged with a charger, driving the car will not recharge it properly. The alternator is only meant to maintain the battery, not recharge it. Get the battery recharged and verified and then try again.

If you have a capable battery charger, then a dead battery can be recharged. I would suggest recharging the battery to the proper voltage and then letting it set for 24 hours. In 24 hours check the battery for the correct voltage. If it maintains the charge, then you should be okay to reinstall the battery. If it does not, then you may have a dead cell in the battery and it would need to be replaced. Video about How to Test Battery

Have you thought that maybe it's time to buy a new battery?

Be sure to charge your batteries fully before installing them. If the batteries are non-rechargeable, dispose of the old batteries properly, and then replace them.
Rechargeable batteries have a limited number of charge/discharge cycles before they become exhausted. If your rechargeable batteries are dead after a full charge cycle, they may also need to be replaced.

That means you have to put new batteries in your scanner... or recharge your rechargable batteries but if you use rechargable batteries use your yellow battery cradle for rechargeable batteries and your black cradle for alakline batteries....foe pro 82...

Nokia phones are notorious for slow response time when recharging from a completely dead battery.

Remove battery.
Make sure there is good contact between all of the contact points.
Replace battery.
plug in charger.
wait for at least 5 min.
If recharge symbol does not appear in window, then one of these things has occurred:
1. Phone has internal damage or water damage. no way to fix without nokia service.
2. Battery is dead. Try a new battery
3. Charger is bad. Try a new/different car charger or home charger.
These chargers are very inexpensive on Craigs List, try to solve it before throwing away the phone. Good luck,

Usually the problem is in your battery, they develop a memory, they will only charge to a certain point. This can happen when the battery is recharged when it is not completely dead.
The key is to let the battery go completely dead, before recharging. I will wait till the battery is dead, then tape the trigger down and let the drill run till it won't move any more.
Sometimes you can reverse the battery memory, by doing the above, but when the battery is that bad, you might need to start with a new battery, and make sure it is completely drained, before charging it.
Wish you the best of luck.

the battery's are most likely dead, (like the real dead) after many uses of rechargeable battery's they slow stop holding charge at all, make sure when you get a new rechargeable battery you fully charge it once and fully discharge it once this will increase batterys life time

a. The battery is dead, recharge.

b. The battery is dead and cannot be recharged, must replace.
