There is a sticker on it that says "Charge immediately after purchase for 36hrs." But the display already says 100. Should I still charge it for 36hr?

I got a similar unit recently and when I plugged it in, it too showed 100% charged. However, I unplugged the charger and checked the battery voltage which instantly dropped to under 6V. So that told me that the battery wasn't accepting a charge and the "100%" reading was coming from the charger just while plugged in. So I left it plugged in and after an hour it did start accepting a charge and the reading dropped to 60% or such. So it does take at least 12 hours, after that if it starts displaying 100% it probably is charged.

charge it to be safe,when you plug the charge in it will automatically start charging at a lower number and work its way up,you can tell how much of a charge it needs by how long it takes to get back to 100%,you cant over charge it so this wont hurt it,once your sure its 100% only charge it when it gets low,if its fully charged your just wasting electricity!!!!!

I charged mine the first time for 8 hours (overnight) and have had to charge it two other times in a four month period. How are you able to tell you have only 15%?

Yes, I think you might have a problem. I have purchased 2, and both actually charged up with in an hour. Make sure the device you had it plugged into, to charge, didn't go to sleep, and stop charging.

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.

Mine came partially charged, but I expected that. I just charged it gain to to top it off.

Hi. I started charging mine as soon as I unboxed it. It had some charge to it but not 100%. So far mine is ok but I hope both of us didn't get a refurbished product. Maybe someone else will reply too.

Yes, it needs to be charged, it ships from China so it takes a couple weeks to receive it. It needs to charge a few hours at least.

Ooh, i haven't had to charge mine yet, and have had it for over two months now. You might want to return it or exchange it.

I had to charge mine. I put them in my charger and it noted them at the bottom of the "charge bar" on the display and it took several hours to get them to full charge. Based on my experience I would say they are not "pre-charged" at all.

Mine was working great after few hours charging. After a year and half, it did not charge like yours. I used to buy used one and used every week, so I gues it died. I used for long and good. But if it is new, then you need refund it

If you have fully charged to time stated, and it is still showing 69%, then return ASAP. Mine has been great and I have had it over a year.

Hi..... To the best of my memory.... It came about 3/4 charged but it has worked perfectly. I remember that I had to attach it to the laptop to bring it up to 100%. I have not had any problems with it in over a year. I hope that helped you.....Bill

Mine came approximately 60% charged. I'd make sure that it is hitting the contacts correctly, and try to charge it. If it won't hold a charge return/replace it.

Youre supposed to let it charge for a few hours the first day you get it. If that doesnt work maybe you should contact the company and get a new one.

if you can smell the battery it probably is bad or your overcharging it.. How long you should charge your battery is totally dependant upon how many milliamps or mA it has. If it has 1400mA it will charge much faster than a battery with 2800mA. Now look at your converter, you will notice several things on the sticker that will be affixed to it. We are looking for the output rating on it specifically. It usually says something like "OUTPUT: DC 8.4v 300mA" but changes from brand to brand and model to model. See that 300mA on the charge? That's how many mA its charges per hour so if you have a 1500mA battery and a 300mA charger its just simple math from this point.So it will take 5 hours total to charge a completely dead/new battery to its full capacity. You simply divide the mA on the charge to the mA of your battery and you will get the time it should take to fully charge a completely drained battery. This does mean to set it and forget it though. In most cases your battery has already been charged once even if still new for quality control purposes so you really need to keep an eye on your battery still.

It means it's already charged. The problem I had though, with two that I ordered, is that neither one would charge at all or even indicate they were plugged it. I ended up returning them both. I think they were scrappy refurbs or simple repages of previously broken returns, but can't prove it.

I may have some residual charge from its manufacture, but it is by no means "fully charged" when received. To fully charge it, you must connect it to whatever device or charger to which it is a component.
