To store a li ion battery do you charge to 50 % or 100 % .

you should store at about 3.8 volts per cell for the mjx battery this is 7.4 to 7.6 volts or about 50%

I have found that these batteries that the blue heat shrink, will either go bad if the are fully charged or discharged. I have bought 4 of them, the only way to use them is to keep them cycling the charge. I have switched to the green heat shrink battery which you can buy on amazon. The only thing with those are they are lighter, so you have to add some nose weight to the front of the bird to make it fly better. The green batteries also will hold a charge better and your flying time is longer. I am actually building my own battery packs now, because these cheap ones don't last.

It takes a while to fully charge it would be around 80 percent from a dead battery.it does its what it says.

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.

I store the battery in the vacuum til it is less than half way needing a charge. That way it is ready when I need it. Anything less than half a charge, it goes into its charger on my countertop for 3 (or so) hours to fully charge it again.

I haven't had it long enough to know if it is months, but Lithium Ion batteries have very good shelf life in general. If you are talking about as a back-up for a phone, the fact that it gives 5-6 charges means that even if you lost 20-30% over a couple of months you would still have several charges. Over the weeks that it has sat in our house it hasn't lost even 25% (still reads 4 bars). Storing in a hot environment will degrade the life of the battery so I would recommend against storing it in a hot vehicle where temps can reach 110 or more over the summer.

The lithium-ion batteries hold their charge quite well but I always plug my battery back in 15-20 minutes before I use it to top it up.

keep your battery indoors to charge/when not in use. do not set in garage, it gets too hot in the summer my home is never below 60 degrees nor above 85, that is the opitmal tempurature of these Lithium Ion battery packs, the only time to keep them out is when your doing the yardwork as it is usually well above 80(where I like in Oklahoma) in those seasons of course that goes without saying! The tollerance is quite high, but the directions say it is best stored/charged at room tempurature indoors, not in a shed or garge.

Li Ion batteries hold their charge much longer than older rechargeable technologies. I have left mine on the desk for better than two months and it still had enough juice to recharge my tablet (~2600mah) and I think there was still some capacity left.

Fully discharging a battery is hard on Li-ion batteries. You should try to not let it go below 20%, though having it plugged in all the time also isn't good for it. Newer laptops have a mode that will keep the battery around 80% charged if you have it plugged in all the time.

I don't remember if it had any charge when I got it, but I always fully charge the batteries so they are ready for use. I don't want them to die on me when I need them.

When you charge it, it will go by percentage rate of charge and when it hits 100 percent it will show it. It will look like a battery when fully charged with the percentage signs in there. You might have to play with the prongs to get it start charging. When you slide the battery in make sure one is on the plus and minus areas on the battery contact points.

Too early for me to give you a statistically accurate assessment. However, if you are going to store this battery for some time I would bring the charge down to about 40 percent charge and then store it (non usage).

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.

Yes. Remember that the standard for the rechargeable may be different, ie the rechargeable may never test at 100 percent.

Most LiIon batteries only come partially charged and need to be fully charged once you take delivery. There is a partial charge that is part of the manufacture of the batteries, but the cells are not fully charged as a safety measure. Batteries that have a full charge can be hazardous if damaged in shipping. There is a lot of energy stored in a small space. A short circuit or crushing the cells can cause fire.

It's Ni-CD which means it won't be chargeable as long as the lithium ION battery and it will not hold as long as the li-ion battery either which means you won't get very long run off that battery. you take the battery pack off and go charge it inside your house on it's charger.

Older batteries used to be susceptible to "memory" meaning if you kept charging it when it was only 1/2 discharged it would eventually think it was dead at 1/2 full. Memory free means you can charge it whenever you feel like it without worrying about the memory thing.
