What are the recommended charging practices for these batteries? Not really any instructions on that.

My under standing has alway been to fully charge them before use and then run them down to like 5 percent before fully charging again. I think you are supposed to do this the first few charges. I have never really found that this makes a difference. Just keep I mind you won't get full battery life until your batteries have gone though a few charge cycles.

I personally do the same thing for all Li-Ion batteries which is use the charge they have from factory until 0% then charge back up to 100% on an external charger and then use until 0% without charging in between to get a good idea on duration.

Some to Most of the answers about Lithium Batteries on this panel are NOT correct. Lithium Ion batteries have an average of 500 cycles of charges. One Cycle is charging from 0% to 100%. If you charge from 50% to 100% that would be equivalent to a Half cycle of .5 of a cycle. YOU DO NOT HAVE TO COMPLETELY CHARGE AND THEN CHARGE. That was for Nickel Cadnium batteries as those batteries would create a memory of continuous 50% to 100% and you would create a battery with half a charge of its potential. That is why you would fully discharge then fully charge. It does not matter if you leave it on charger even after it has completed charge. Chips tell it to stop charging. If you can keep your phone or tablet with a Lithium Ion battery and you were using it for long period of time where it stays in one place, it is best to keep it on plugged into a charger as it wouldn't be going through a cycle. In other words, if it is in dock and you connect to stereo or TV, that is the best thing to do to prolong the life of your battery. These are some tips from Leo Laporte The Tech Guy on his broadcast. Very good and helpful tips, I might add.

When the light on the wall charger is purple the battery is charging, but if blue it's fully charged. If you store lithium batteries for a long period of time don't have more then 50% charge. Also, don't leave a lithium battery in the charger for a long period of time after its been charged. This will lessen the longevity of the battery. Don't leave the charger plugged in without the battery.

You should charge the battery until the adapter's light turn blue. When the battery is charging, the light turns red and once it is fully charged, the light turns blue. If you have any further inquires, please contact us back at our customer service email. Thank you.

charge ones not charging by themselves, first on one side then on otherside getting orange light, until you get a green light. Then repeat for other once. I have two batteries out of 6 that I have to do the same thing on. It is like you have to find the spot where it will charge. Phil

Jeff, I have used them without problem for months now. It may just be that you got a bum set. I have been running only Oly BLN-1s in my OM-Ds and E-M1 for the last two months, so decided to see how my Wasabi batteries were doing in my bag having not been on a charger in more than two months just for this response. I can say that BOTH my Wasabis were still fully charged (based on my E-M1's battery display) and are working fine. I'd suggest contacting them to see if they can help you out. Jamie.

Hi Gregory! I just asked the question of the best "proven" way to charge these batts and I'm convinced by the majority of answers is to use the USB end and keep the mAh's the same 1 thru 5, of course. It will take longer, but successful all around, as many have said and I tend to agree. Some have used, me included, a 3.7V wall charger, but I don't feel any longer. I hope that this helps and puts your mind at ease as it does mine!�

Get a Nitecore charger. Don't bother with any other charger for these batteries. Charge both of them when you get them.

Have you properly installed batteries? Have you charged them if they are rechargeable?

The first time you charge them should at least be over night, just like a phone battery. Other wise it wont keep a charge.

Hey J YO,It's hard to say. I haven't actually charged them yet. I used them out of the package, factory charge and they are STILL going. I'll update you once I charge and use them a couple times. The factory charge, thus far, is our performing ANY rechargeable I've ever used, and any alkaline, for that matter. It also may be the charger though. I did not purchase a new charger for these batteries as I already have two. Have you been charging yours with an old charger?

I just plug the batteries in for around 8 hours and use em. It works well for me. I hope this helps. I had also purchased new batteries and I charged them overnight the first time. GOOD LUCK

Both of my batteries arrived about 50% charged. Each took about 4-5 hours to fully charge (red LED goes off and blue is lit). It's just a very low power charger. A slow charge is supposed to be good for the batteries, but it's not good for me when I'm in a hurry. When traveling I'll charge them in the phone with a 2 amp charger.

I'm in North America. Make sure that the positive side of the batteries are put into the position in the charger where the positive polarities are. Make sure that the negative sides are where the negative side of the charger is. There should be a latch on the negative side pushing them forward to charge. I put these batteries into a high power LED flashlight. They are outstandingly powerful. Good luck.

New batteries are shipped with little charge. They should be charged for 4-6 hours before use

When I ordered this product, it contained instructions for how to properly charge the battery for the first time. If I recall correctly, they recommended a full charge to 100% before use, and then unplugging the laptop and letting the battery drain all the way to 0%. Beyond that I don't remember any other tips. However here's a website that provides additional suggestions. The main point is NOT to keep your battery running at 100% AND plugged in at all times.https://www.luculentsystems.com/techblog/how-to-extend-laptops-battery-life-span/

Regular or rechargeable batteries work in these. Nothing special is needed. If they aren't working, they're probably defective. That happened with one of mine, as well.

Recharge these anytime. In fact, best to NOT let these run down entirely, as these (unlike Ni-Cad) have no 'memory.'Mainly don't overcharge. These take about a 2 hour charge, and overcharging in an attempt to bring them up to full capacity cause battery 'stress.' You can get the full, more scientific answers to your questions if you Google. Also, remove from charger after charging.

Just put them in the charger, side by side. Batteries must be charged in pairs, either two or four at a time, and they must be of the same type. If they are not charging, one of them may be bad. Try switching one of them to find and get rid of the bad one.

I think not using them for such a long time has killed the battery. I have left regular chargeable batteries sit for a long time and they would not charge either. I think regular use is the key.
