Looks like the battery is leaking power rather quickly when not in use. Mine had 4 bars and ~24 hours later it had only 3 bars.Anybody else?

I charged mine a couple days ago, and just looked and it still has 4 bar . I have not noticed any leakage. I do try to hold the button down and turn it off when I am not using it.

Mine holds its power for weeks on end if it's not being used - it was fully charged the end of December and I used it for the first time this year on March 20th. It opened at 4 bars and charged up my phone and computer just fine and still had 2 bars..... Thinking you might want to contact the manufacturer or Amazon if it's a fairly new purchase.

Mine works great but if you don't use it it will lose some power you can charge it 2 ways when you are not using it leave it in the sun light

Hmm, good question. I wonder if the connection to the battery is bad? Maybe it was connected for the first 14 hours and then got jarred loose somehow? I would probably take the battery out and put it back in, making sure that the contacts seem to be clean and touching. If that doesn't do anything, I would call a local battery store and see if they have any way of testing the battery to see if it is good. If there is nothing obvious wrong with the battery, I would probably call the company that installed the unit and see if they have any suggestions. Sorry I couldn't be of more help.

I'm not sure. I would check with Cobra first. I have a local battery supplier that is good with finding things like this. I'm still using the original battery. I discharge it fully before hunting season. Then may have on for 8-12 hours a day and only recharge after 3 days and still have 3 bars usually. If your using more than this then may need a spare. If battery not holding charge let Cobra know and see if you need replacement, otherwise try the above. Hope that helps.

its great 4 me! Just make sure u turn it off by hand and dont leave it on standby. I did that once and it died. I've charged it a few times. I use it @ work only and my battery life was only 1 bar down after 7 hrs. All i do is listen to music i dont know if it drains faster doing other things. Hope this helps.

Hi, I have not used it that long, but so far, the battery is holding up. Have not tested it on an all day run!Sorry I can't be of more help!

Unfortunately, I have the same problem and no amount of charging is fixing it. It almost feels like there is actually no battery inside, or it used up its number of possible recharges. Returning it to Amazon. Will try one more time to order this thing.

Yeah I have noticed this same issue. I dim it down and set the lock out screen to 5 seconds and it helps tremendously however, it still drains fast. Solution I found that works is to always keep a charger nearby and keep it plugged in and if possible, watch it in a dim setting. Battery extends but not much.

I purchased mine 6 weeks ago and am now having the same issue. I am wondering if yours and mine are from a bad lot. I have emailed the seller directly (per Amazon's instructions for defective batteries) and am waiting to receive an answer. I will most likely email the address on the box it came in if I don't hear back from the seller very soon.

I understand your problem, but as I have not had a similar experience, I can only theorize as to a solution. It sounds as though you may have a defective or worn out battery; like any other battery, this one may last only so long. If this is the case and there is a warranty on the battery, you may be able to obtain a replacement by contacting the manufacturer. It's either that or purchase a new battery. Sorry.

I am even wondering: was this mess with the batteries intended to attract customers anxious to receive "unadvertised" bigger batteries just to boost initial sales? I am sorry for those who are now starting to receive the "standard" 4400 mAh battery. But I want to comfort you: even while I have the bigger 5800 mAh one, it seems almost impossible to me to drain even 60% of it in a real life student usage. I never carry an ac adapter with me anymore because I consistently get at least 5 min. per every 1% of battery power I have, with wifi turned on and on 60% of brightness. When wifi is occasionally off, it comes up to more than 6 min. per 1%. So, even if you will get 75% of this, it will still carry you through the whole day of classes and an evening in a starbucks. Anyways, I would not trade acer for asus even if I got smaller battery, because acer has unparalleled screen in terms of clarity and brightness.

If it isn't a low battery, it's probably gotten wet inside... try popping off the top (like you're replacing the battery) and just leaving it out to dry a bit. After an aggressive session with mine, I will find it a little soggy inside, and the meter will eventually show some numbers then fade away when turned on. Popping off the top and leaving it out a couple dozen hours seems to do the trick.

I have also noticed that one of mine also when fully charged and used little drains very quickly. This is not normal for a good lithium.I have only used one of the two but makes me worry.

Wow i thought i was the only one... i bought it just over a year and a half and mine has stopped holding its charge aswell. I believe a new battery would solve the problem though. If you find one please let me know aswell.

I tested mine yesterday, It was a 1 bar and it took 3 hours to come to full charge. Hope this help you with a guideline.

I believe the load is too high. There's not a lot of amp/hours in the battery, and I think it's designed for loads in the mAh range at low resistance. You need a battery capable of supplying about 6 amps (70 watts at 12 volts is 5.8 amps) continuously for the period you need (and probably a way to recharge it to avoid continuous replacement).

I'm guessing the leaking battery acid either corroded a terminal or it's covered with rust to the point it wont conduct electricity. You can try cleaning and inspecting the connections if you like. I wouldn't bother..just get a new one. Make sure you wear gloves. You don't want to get battery acid on your skin.

since this question popped up, i ran mine for the last two hours and it's still going strong. i'm using the Sony battery (actually a generic copy), so your mileage may vary based on battery type. i don't think this was fully charged when i started, but only has one bar left now. but it did run full blast for 2 hours.
