What is the best way to charge these batteries to ensure longest life and most effective use?

You might want to Google this one. But understand you need to charge the battery All the way and let it discharge almost All the way for the first couple of charges.

You can try calibrate the battery for its best performance:1.Disconnect the charger and use the battery until there is 10% power left.2.Connect the charger until the battery is charged to 100%. Please do not use the phone during this charging process and try these steps for 3 or 4 times

Most Li-ion battery manufacturers recommend that you charge fully, remove from charger as soon as possible after battery is charged and don't let them run down completely. I usually re-charge mine when they are about 30 percent remaining. I keep a spare battery and rotate them whenever I can. Manufacturers also don't recommend storing a fully charged battery for extended periods. That's why I rotate mine. I have never heard a reason for not storing a fully charged battery - maybe someone else has the answer to that.

I charged it as normal. I pretty much use it until it reaches around 20% battery life. I also keep my phone plugged in most of the time when under heavy use.

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.

I would say either works. Most recharge stations have a mechanism to not charge anymore once its fully charged. I have had mine for 5-6 months and I keep them plugged in, and I have not experienced any degradation of charge life or anything. I guess it would be your preference.

Like everything else, the chargers have a life span. But it's quite long. I have 4 of them and have used them constantly for three years. They're still working fine. Just make sure you recharge them when they are depleted. And don't use them until they are completely dead. When they start getting weak, exchange them for a freshly charged battery, and put the depleted one on the charger. If you use any rechargeable battery until it's totally dead, you will shorten their live span.

I have not done that as of yet. It is my understanding you can leave them in as long as you want and a trickle charge will keep them at full charge. This info was from another sight.

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.

plug charger into 110v outlet..put in rechargeable batteries,and it will charge them up.

I have multiple batteries to recharge,so I keep rotating them. I never thought of any problem with keeping them in the charger.Once they're done,I take them out so I know they're OK to use

I would add to my previous comment that you would want to bring them to full charge with charger and use the BatteryMinder only as a maintainer/desulfator. They should all be in similar condition. If you find one 12v pairing has a lesser condition, I would suggest desulfating the pairs separately, spending more time on the weaker pair. From what I understand, desulfating a bank in series/parallel will tend to favor the batteries that are in better condition. You can make a Kentucky windage determination of condition by measuring resting voltage or be more precise by measuring specific gravity of each cell.

It would be best to. I have always liked to fully charge my batteries before I use them for the first time.

This is typically hard to gauge since you can put either regular alkaline batteries or rechargeable batteries I currently have rechargeable batteries in since they last the longest of any non rechargeables, I am using Sanyo batteries and their charger, they typically last me about three months that is if I don't use them on high drain things like games and with games about two months

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.

yea it will be fine to leave it plugged in and the batteries in. they are lithium ion type batteries the same kind in laptops and cell phones. so they will charge up then the charger will just keep them charged till your ready to use them, i dont know about long term though like over a week or two probably wouldnt be great for them.

lithium batteries you need to charge will be better I think.. but I suggest to use a 1800+ mAh ones... higher the number, easier the life....

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.

Either will work fine. I leave mine on 500 since I'm usually not in a hurry for my batteries. Add a guideline you generally charge lithium ion batteries at one half capacity per hour, unless otherwise specified by the battery manufacturer.

the batteries are charged at a certain percentage, best for storage. its not fully charged
