I installed the battery and even after 8 hours the panel still reports "low battery". How long does it take for the battery to fully charge?

Mine recharged right away. I have had no problems. I followed the installing of the new battery from the video on the computer.instructions Perhaps your new battery is bad.

I can't honestly remember exactly how long it took for the low battery to go away, but want to say it was at least 24hrs. I would give it 2 full days before contacting the seller. Good Luck!

You don't....just replace the old battery with the fresh one...it will take anywhere from 24 to 48 hours. It may seem like it is a dud, but give time and hopefully, it recharges as expected (30-days to return if you suspect it to be a real dud). My replacement took about 30 some hours to be fully charged. In the mean time, I kept getting some odd codes from on my Ademco panel. Once sufficiently charged, the codes went away. Oh, yeah, after sufficiently charged, it gave me a code that my battery in the motion sensor also needed to be replaced. My old battery and the motion sensor battery lasted more than six years.

It sounds like something may be defective or the battery is dying out, as it should only take a couple hours to charge. I cannot recall it taking more than hours. You may want to use a power block instead of a computer to charge it to make sure the problem isn't with say a weak laptop battery.

I've never let mine get completely down to 0%, the lowest I let it get down to is 20%, but so far on an average charge, is usually 6-7 hours. These are larger batteries than most so will take longer to charge.

Is it possible the battery is not charged? The instructions suggest it is necessary to discharge fully then recharge. It may be it came discharged, and must be on charge to be recognized, I bought an inexpensive battery and it lasted about three days, then began indicating it should be replaced. The only other possibility would be an incorrect battery? Best regards, Sammy

Only have it in there when it needs it. Try to get the battery level as low as you can. It shouldn't take more than a 4 hours to charge. Mine usually takes 2-3 hours.

The customer representative said that its an error that they've recognized. Just charge it for some time and you'll be good.mine has the same problem too but the battery lasts long enough.The problem is with the battery level indicator and not with the battery. If your deck gives poor battery life then you should complain to the customer service.

Mine was nearly fully charged when I received it. I have not run the battery completely dead during any single use yet, so I can't be certain. I would guess it should fully charge within an hour.

Send it back! It takes around 4 hours to charge mine from dead to fulling charged.

When mine starts to go a little dim I plug it in at the end of the day an its ready to go the next morning.sorry but I don't know how many hours it takes exactly. I don't think the battery will last for a straight 8 hr but it should last a straight 4 hr. I like mine very much and would buy another one. And its tougher than some people say, I left mine under the car when i let it down, an all that broke was the hook on the top, a little NP1 and its fine.

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.

The directions I got with the last battery I purchased on Amazon is to charge for 18 hours, then run it down to 8% for the first five cycles. Hope this helps

I always charge the battery in the night time. It usually takes eight hours to get fully charged.

I have only had it a short time but if it gets a full 7 hour initial charge then run it down, which takes about 15 to 20 minutes, then re charge mine runs at least 30 minutes now and should go longer as the recharge process is repeated. I hope this was helpful

My new battery was already charged and I used it right away. Then when I loose a bar I charge it about 20 min. when the battery light stops flashing which indicates the battery is fully charged.

I think you may have gotten a defect battery because I only charged mine for an hour or 2 when I first got it. (I disconnected it because the charged light turned green) and I was able to use it all day yesterday and today. I still haven't gotten the low batter indicator.

i have the 10 watt solar panel which is properly charging the battery. Check the charge light inside to make sure it is charging in sunlight. make sure the wires are not reversed as it will not properly charge. Mine has been working for about 5 months
