Does the battery come charged? The green lights on it are at 2, with a 3rd flashing; is it charging?

It wasn't completely charged. We let it charge til completely green. Once it was done we unplugged it and used it til it died to calibrate it then it charged easily after that.

Mine did not come charged. I spent some time charging it up. The light did flash but I remember it was fully charged when all five lights were on. My suggestion would be to check the power readings on your MacBook and see if it indicates charging. Also constantly monitor power percentage levels. If it isn't increasing then you have a bad battery. HTH

I returned this battery because it didn't fit properly and a "Service battery" message would not go away. I don't think it charged properly. This battery is not a good buy as you can see from the large number of poor reviews. Save your money up to get a genuine replacement.

When I charge them the green light flashes - I know it's fully charged when the green light is steadily on. It takes maybe 20 minutes.

If the red and green light come on together, it isn't charging. When it is charging, only the red light should come on along with the fan (which you can hear). I had problems getting my charger to work - sent it back and will order another since most reviews were positive.

don't count on any new battery to be fully charged! mine had a charge but I'm sure it was not 100% charged. Once installed your system should start charging it.

I have this charger (2nd one), the red light only appears when the battery is at its lowest charge and will begin flashing green as it charges up. When the green light stays on, you battery is fully charged.

when the red light on steadily on -indicates the charger is hooked up correctly and is chargingwhen the green light is flashing it means the battery is charged to 80% or greaterwhen the green light is a solid green (no flashing) the battery is fully charged and the microprocessor is monitoring the battery and will keep it fully chargedall this information is on page 7 of the instructions provided with the unit

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.

With mine, all the green lights are on when it's fully charged, but now always. I have no idea what the red light means. It may be just for show. I wouldn't buy another one of these, though. It works 95% of the time. Sometimes I pull the battery off after a few hours, and it hasn't charged. It didn't come with any type of documentation.

It blinks green when its charging then solid green when its charged....Move the cables n put a little Vaseline on the battery . This works for me.

I bought it to maintain charge on a battery over the winter. The green light soon came on and I assume it is maintaining a charged condition. I won't really know until I put the battery in the car when the weather improves and see if it starts up okay. Quick charging was not a factor in my purchase decision. Maintaining a charged condition was the main consideration.

My light (green) stay's on when charging. It goes off when complete. Mine only blinks when the battery is low. It sounds as if your battery might be faulty.I never use tech support on anything. They usually know less about their products than we do!

I charge it in the charger and it has a light that if I remember turns green when it is fully charged. The biggest problem is the camera cannot commumicate with the battery to display the amount of battery charge.

The charger flashes green when charging and is a solid green when done. I have two along with two batteries for my weedeater.

The light starts as red and goes to green when charged. Mine does not fully charge and may only be half charged when the light turns to green.

one of the lights is blinking and once the battery is fully charged the light turns green!

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.
