How long should I charge a dead battery?

You should charge your dead battery overnight, especially if you just ordered your mower, and have not used it.

I am afraid I dont know. For me, once the battery was dead, it was dead. No amount of charging seemed to help.

Johnnie, never ever have had a completely dead battery. After mowing both front and back yard I charge for 24 hours and then take it offthe charger. This battery seems to have a lot more power/storage than my previous one. I've gone 3 weeks between mowings and still have full power between charges.

I charge mine for 16 to 20 hours and I also bought a second one to use in the mean time.

Let it charge for 8 to 12 hours. It charges slowat first this helps the battery live longer. you want long term battery health let it charge 100 percent. Then it should be good. I love mine!

The polarity is correct. This unit will not charge a dead battery. It only outputs enough power to maintain a charged one. You will need a plug-in style charger that outputs about 14 volts at approx. 2 amps for 6 hours or so, then test the battery. Charge it at a low rate to try to revive it. If it comes back and holds charge, it should read about 12.8 volts fully charged.

Depends on how long you have had the battery and if you have damaged it or properly installed it when building your model. However I would recommend charging it for 30minutes if its low on charge and an 1 or more if you almost depleted it. However please charge the battery in a lipo lithium bag, because in some cases during charging if overcharged or any thing goes wrong within the battery cells the battery itself may overheat and catch fire. Please never charge it without supervision always monitor it and unplug it if not in use.

Should be around 8 hours. I found mine wasn't working so I open up the battery compartment and found the battery wasn't hooked up. Once I hook the battery up to the unit it work perfectly. Your battery could be disconnect hence is not holding the charge. Worth looking into this. Good luck.

I'd start with a new battery....and since it has a memory you will need to let it run all the down in order to get a full charge and then leave on the charger about 3 hours maximum time.

I would charge it for a full 15 hours before using it. They usually come partially charged, so doing a full charge is the best way to be sure.

Probably an hour for a full charge. I finally had to replace my battery because it would not hold a charge. Pull yours out and see if it is bulged in the middle. If so it is bad.

Unplug it, let it drain conpletely. The recharge it. Make sure it is charging and charge it no less than 6 hours. I found the battery lasts a long time but needs about 30% to power up. Charging for 3 hours wasn't wasn't enough. If it doesn't work ten sed it back . It needs a good but of power to start

It will take several hours to charge enough to start the car. If the battery is in poor condition, and the voltage output of the battery is below 2 volts DC, the charger will not charge the battery at all and just shows a floating charge. This is covered in the instructions. It may be time to replace your battery altogether.

You should make sure your battery is seated properly - the negative side of the battery should be against the spring. If the battery does not make contact with the charging points, of the charger, it will not charge the battery. If your battery cell is drained then you should allow the battery to charge for at least 4 hours. If you feel the battery or charger is defective contact the seller and they will replace either one of them. This is very rare but it is possible.

I would expect a few hours for a full charge. What indicators do you have of battery level? There are indicators on the bottom of many packs. Push the button and see how many lights show. Also, if you are using your computer heavily with screen at full brightness, a lot of the juice will go into running the laptop. There won't be much left to recharge the battery. You might try putting it aside to sleep for an hour and checking back later. Of course, if the battery is bad or the calibration is way off, that is another thing. If you charge a sleeping computer all night and only get 30 minutes of use before it's dead again, that's not good. There are ways to address that but someone else may know off the top of their head.

If it is totally dead it may not work. For dead batteries a manual charger works better.

Make sure you wait 15 minutes after using your battery before you charge it. If you charge it right after you use it they won't last long. You have to let them cool down.

2 hours max. After using one battery until the camera turned off, I took it home and charged it to max capacity and it was a little under 2 hours. You may want to contact the seller. If it is the same seller I used, they are excellent and will replace the dead cell. But first use a different outlet to see if you are getting 100% from your outlet. Just a suggestion.

Hmm - I don't know that I've ever really checked the amount of time it takes to go from completely dead to a full charge. I normally just plug it in to an outlet and leave it for an hour or two and then it's good to go. You can also use the USB to charge it on your computer - which is nice. It's really a nice little charger - I use it all the time on trips, or if I know I'm going to be away from the house all day I'll keep it in my pocket just as a safety measure in case my phone battery dies.

A brand new battery can take up to 3 hours to fully charge. After the battery has been charged and depleted to under 5% about ten times, the charge that is held takes about 2 - 2.5 hours to fully charge.
