How long to charge batteries?
1984642
I had the same question after i received the charger, there were no instructions with it. It came wraped in a peice of plastic. I ended up purchasing a new charger with a digital guage so i could tell if the battery was fully charged.

I was told to take them off the charger as soon as the light turned green. Don't leave them on the charger.

Depends on your charger, and how much capacity the batteries actually have (most Ultrafire batteries have false mAh markings). I wouldn't buy these, all except for one I've ever heard of were bad batteries, and even that purchaser found the capacity was 2000 some mAh. I'd find some Panasonic 3100 or 3400mAh protected batteries instead, these Ultrafires are not worth it.

These are facile batteries and charging is difficult to pin down. The first time I charged them it was maybe about and hour, but they were not completely drained either.They should not be over charged are over used in my experience. They get really warm in the torches and will at this point discharge rather fast. I try and watch them when charging because I really don't trust them, when the Green light comes on I take them off the charger quickly, hope this helps.. PS: this is the first time I have had all eight being in perfect working order since I started using them.

3 hours max. Mine usually take 2 hours to recharge, but I don't run them all the way down.

That depends on the battery. When I charge my lipo 2s 5000 mAH battery, its under an hour. Also, there is a quick charge feature if i;m not mistaken. There are reviews of this charger on youtube so you might want to check that out as well.

I have a few of these chargers and many of these batteries. If your charging two at the same time that are almost drained you can expect a full charge in about 3 hours.......Hope this helped.

As the others said, it varies.But in my experience, on 200 mA it charges the fastest batteries in about four hours, and my oldest batteries take around 24 hours.

It depends on how much you have depleted the batteries from its last use. For AA batteries that have been mostly depleted from my last use, I found that it takes me about 7 and one-half hours to recharge it.

They aren't quick-charge batteries, but the charge will stay a long time, unlike nicads. Charge time varies, but it's around 8 hours if they are mostly depleted. There are blinking lights when you start charging, then go solid when finished. Each battery is charged individually so one could be done and another still blinking and charging.

One or two hours at most. The worst thing is to run them all the way down, then put on the charger and forget about them. If you will look on Amazon. Under some or the batteries, they give you the do's and don't of how to get the most life out of your batteries.

It charges in about an hour. Just watch the light; it lets you know when it has finished charging. I have accidently left batteries on a charger overnight without any damage but that shouldn't be done as a general practice.

when i timed it for the AA batteries it took about 3.5 to 4 hours. It will charge partially charged batteries but this one needs to be done in pairs. It's an easy to use charger, if you need something to charge quickly wouldn't recommend this. i typically use my other charger which is a rapid charger, charges my batteries in about an hour.

It depends on the charge and how much current is pushed through the battery. Faster charging heats the battery, which is not good for it, so you have to balance speed vs lifetime. I use a smart charger (a small LaCrosse) and keep it at the lowest setting, and fully discharged batteries take about 8 hours to charge. I put them in before work and they are ready when I get back.

i have not rec'd mine yet so i can't be sure.I have an older charger that will do NiCad and nimh. it takes 13 hours ti do a set of 2 or 4. some batteries can be charged faster than others so I guess some chargers might charge faster than others.

as far as I know the charger works like a car charger or trickle charger. My batteries usually charge within 3 hours. But the design is meant so your batteries will not be over charged and will not be liable to explode or rupture. It's strictly a safety factor built within the device. The size of the battery matters as well. Hope this helped!

I am not really sure, i have a total of 3 batteries, so when/if one goes dead, i just pop it in the charger and it stays till i need it again. My android phone takes a while to charge, even on its own w/o any apps running. My guess it takes about 3 hours from completely dead to charge.

Using a 1A charger, it took me about 7 hours to charge from empty. Keep in mind that when the battery is very low or near full capacity, the charging rate is less than 1A due to the design of lithium batteries.

My 2 cellphones use this kind of batteries. From my experience it takes about 3 to 4 hours to fully charge them. They seem to work fine for me.

About a half hour. Then the charge lasts about 10 minutes. Purchase multiple batteries!
