do you charge it fully before you use them or you drain them then charge it?

with lithium ion batteries you can charge them at any time, they dont have the memory effect of Ni-Cd batteries, you can recharge at any point that is convenient. These batteries have flush terminals and will not work in equipment that does not has a protruding tab for each side of the battery. these batteries cant be used in cascade serial arrangements, they will not make contact with each other.

You should never fully discharge Li-Ion batteries, it will destroy them, and any decent charger will refuse to charge dead Li-Ion's. They come new charged at 90%, so it's OK to use them. When they are at 2.7v, they need to be charged. It's OK to charge often, they don't have a cycle life, just a shelf life.

Do not drain them. Charge overnight BEFORE you use them. I know in the past to drain then charge, but not with these.

I fully charge first then recharge when they drop below 3.7 volts I read that letting them get to cut off point 3.2v is not really good for them.

I would charge the battery first. I believe those are the instructions anyway. In fact, I believe there are specific charging procedures initially to get the best life out of the battery. If you continue to experience issues, I would contact the vendor/manufacturer.

A full charge and then don't run it all the way down. That was only good for older Li-ion batteries. I like to also charge new batteries for a few hours over the necessary time just out of habit.

By pressing that red button, you can completely discharge the batteries before charging them. If you don't press the button it will the charge batteries from whatever percentage of charge they have to full charge!

I really don't know. From what I understand with any battery you should fully charge the battery before each use and you should fully let it die (don't keep it plugged in while you are using the computer at the same time). Not that many people actually fallow these suggested steps but they help to is that to elongate battery life.

I charge both my trolling and starting batteries as the charger goes to float charging after the batteries are fully charged. I like to know that both batteries are ready to go in the morning.

The life and performance of a battery does not depend on the divice they are used, but on the quality and characteristics of the battery itself. Consult the battery manufacture and follow the recomended charge intervals. Some batteries must be drained before charging it back while others can not be allowed to drain completely. Check it out with the manufacture...

Mines does that only when it needs to be charge.Best thing I think you should do is let it completely drain and die out.

After you do the initial breakin procedure, you're technically supposed to use it until it's fully drained then charge it. I like to get my cake and eat it too, so my opinion is that it sucks to do that, so I charge it whenever I want to so that I can guarantee I have a full battery to start with when I need it. I've been doing that for the last 2 years and the battery life is probably still about 80-90% of what it was when I first got it. I think it's well worth it. It's cheap, so when I feel like it's no longer able to hold a capacity that I'm happy with, scrape it and buy a new one.

I go ahead and charge it. I think you have to charge it now and then even if you don't use it.

I believe either is OK. I usually leave it plugged in during frequent use. For storage, I unplug then charge prior to use.

I usually charge it overnight, then turn it the opposite way in the charger until I need to use it. These batteries hold a charge a very long time. Depending on how long I use it on a given day determines if I charge it that day or not. If I use it for just a couple of screws or drill o few holes, then I wont bother charging it that day. If I use it a lot in one day then I will usually charge it overnight and then the next day turn it backwards in the charger. I know it says they won't overcharge but you don't need to put an extra charge cycle on the battery if it's not necessary. I hope this helps.

They say you should charge it fully. It is the same kind of battery that originally came with my phone and that was the directions for it.

You should traid it out and dont leave your batteries on the charger after they are fully charged.

Great morning to you, Ms. Cherish. YES...initially charge your batter to full strength. Then totally it drain it right down to 0%. This technique ensures that you will get maximum battery performance during the lifetime of your new unit. Use this technique for any Lithium ion battery that you purchase. Do this with cell phones and tablet computers as well.

I drained my battery 100% the first 4 charges. I wouldn't recommend plugging it in everyday as it can decrease the life of the battery. Once your battery is drained to 5-10% after your first 4 full drains, You'll be fine to plug it in. This is what I did. I also made sure that once a month I completely drained the battery. It exercises the battery and keeps it in good health just like when we exercise.

If you have to charge it and you plug it in and both lights or on the y. Stay on till the charge is complete and when they go out the charge is done. Some times over night or maybe just a hour or so depends how drained it is.
