The light will turn blue when its charged! And if you notice, the charger gets a bit warm while charging but when it has finished charging the battery it cools right back down! Won't fry it st all!!

The LED indicator is pink when you initially start to charge and turn blue when the battery is fully charged.

No it won't fry your battery ..it charges the battery good and there is a light on it that changes from red to blue when fully charged

There will be a pinkish hue. When the battery is charged the light will be blue.

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 arrived partially charged. Recommend fully charging it prior to use or testing.

I just received the battery I referred to earlier. The G1 recognized it and it read fully charged out of the box. I'll test for comparison over the next few days and then post the details and overall results. So far, so good.

Hey, I lost my charger. But I have china phone charger with following specifications: 5.7 volts with 800mA.. Can i use it or its gonna burn my bluetooth.

The information I received stated that you can do just that. The battery is a lithium ion and when the charger has completely charged it a light indicates it is full and in standby. I have been using mine for months and love it. Hope this helps and remember amazon has free return policy if you're not happy.

From what I understand from reading the owners manual, that indication is the chargers way of telling you that the battery is very discharged and is only at about 25% of its capacity. The LEDs are supposed to blink, not light up solid, as the charger is charging. If there is nothing wrong with the battery, the charge level should start going up after a while and in a few hours, the LEDs should read at 100% (solid, not blinking, red, red, yellow, green LEDs). I hope this helps you Mary! Michael R

When you charge it, it will go by percentage rate of charge and when it hits 100 percent it will show it. It will look like a battery when fully charged with the percentage signs in there. You might have to play with the prongs to get it start charging. When you slide the battery in make sure one is on the plus and minus areas on the battery contact points.

I've plugged in another brands battery pack like this and when I plugged it in, it instantly showed "fully charged" on it's indicators. However, I wasn't sure so pulled the plug on the charger and checked the battery voltage which was under 6V (showing that it was far from fully charged). So I plugged it back in for the 12+ hours and for the first hour, it stayed showing full (because the battery was resisting the charge power and the charger gave the lights the "full" 14V false reading), but as the battery began accepting the charge it dropped to 60% and then climbed back up over time. So don't be fooled by it showing that "full" within a few minutes, leave it plugged in for at least 12 hours (and by then it should be accepting the charge and the readings should have dropped, so once it raises again you can believe it's really "full".

It is the cheap Chinese made cells they use. I opened one up to get to the bottom as to why these things lose their charge so quickly and got my answer as soon as I tore into the battery lack. As suggested by someone else, either get a battery shop to build you a battery out of better cells (Panasonic or Sanyo would be good choices) or put one together yourself if you have the inclination.

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

It's normal, unfortunately it doesn't have an indicator of when is fully charged. It usually charges in about an hour if not used while charging

Mine did the same thing. It is charging, but the software doesn't recognize it. I installed an app called "coconut battery" to tell me when it was fully charged.

I just had an issue with mine not charging. It got to zero and when I rebooted with it plug into the USB charger, I could see the little lighting bolt on the battery indicating it was trying to charge, but it shut off because of low batter. Kind of a Catch-22. I tried this cycle a few times and was fed up, so I decided to unplug it and let it 'die down' for half a day. Then I plugged it back in and the screen showed me that it was charging! I let it charge up for a few hours and it started up and continued to charge. If you are having charging issues, try letting it run out and "die", then plug it in. Worked for me, YMMV. I just had an issue with mine not charging.

When you plug in the battery the little green light will come on to let you know it's charging. When that light has turned off then the battery is fully charged and you can put a new one in.

Make sure its fully charged. I only figures this out after testing it out and seeing very short videos of the test. I know there has been some complaints of malfunctioning, but mine works fine.
