Care for batteries - when I am not using one, should it be drained, or fully charged before storing? I've already used it 4 cycles-charge- drain fully

I always kept mine fully charge and in my purse for backup. The batteries will be fine, I used mine for a year like this until I got a new phone. The batteries are still in great condition. The true worry comes from leaving them on the charger to long it cause the battery to get hot and expand which makes them go bad much faster.

LiPo batteries should be stored at at a 50-60% charge. At that charge level, they can last for years with very little deterioration. If stored discharged, they can be destroyed in a short time. If stored fully charged, they will lose capacity over time.

Store your batteries fully charged. Also, try to avoid letting lithium ion batteries (like the ones in cell phones) discharge completely after the initial 4-5 cycle "break in" period.. Repeatedly draining them all the way can shorten battery life. Most battery chargers have a protection circuit built in so leaving a battery in the charger past the time it is fully charged will not harm it.

While technically any battery could leak I have never had this happen to these high quality "eneloop" batteries. Keep in mind it is not so much the battery being left in the device as it is where the device itself is left dormant. If there are frequent temperature and humidity changes the device terminals are likely to corrode which could then damage the battery. As with even mechanical devices (such as springs) it is cycling count that eventually takes its toll. There is a lot of technical data available on long term storage and recharging. From what I know you want to allow them to store partially drained, but NOT "dead" as you can get polarity reversals. Also, it is worth the investment on a "smart charger" that will not overheat the battery and will automatically put the battery through beneficial "cycles" to improve performance and life. Also, it is worth monitoring voltages on all your good batteries... remember the pack is degraded by the weakest battery. In summary, store cool partially drained, smart-charge and never let them overheat.

I have 2 batteries for use on my drill and hedge trimmer. Thy are now about 1 year old and have never had a problem. It is important that you do not leave batteries discharged for long periods. When I use the battery, I put it on charge immediately. A charged battery will store fine, a discharged battery will not. If you did not leave the battery discharged, I would suggest that there is a problem with the charger and, since the battery will need to be charged quickly, I would also suggest that you need to do something about this quickly.

I think it's always best to fully charge your battery when you first get it, and then let it run all the way down. They seem to last longer that way. I like my battery it makes my phone last all day. Of course I spend a lot of time on Facebook, Twitter, and emails.

With these type batteries, you will want to use them until they are fully dead before charging to get the most out of them. I would not store it on the charger it self. Any other way will be fine.

As per the instructions you charge it for 12 hours then totally drain the battery 10 to 12 times. Not do it once. It has to do with battery memory. Also use a full 110 wall charger for charging and not a weak USB port to charge.

I leave mine on a charger at all times and it doesn't appear to damage or effect performance. perhaps there is some battery expert out there who can offer a more educated response.

I have repeatly but don't leave it un attended. You should get a deeper charge with just with the battery along in the charger if you have the option.

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/

I haven't timed it, but it takes a few hours.Cody says it's good to drain them fully occasionally. I disagree. From what I've read about Lithium Ion batteries, it's better not to do this. It was true with NiCd and NiMH batteries, but these are very different. On the bright side, you can get away with when necessary. Even better, you can top them up as often as you like. Doing so has nearly no effect on the battery's overall life. This is one of the really nice thing about LiIon batteries.

With this type of battery, the key is to discharge it before recharging. I've got well over 400 "burn hours" of my lamp now and it still holds a charge perfectly. When it's fully charged, I unplug it and burn it for a while, then let it sit until the charge is almost exhausted.

I am not sure it is wise to keep batteries on charge all the time. I always disconnect the charger after a full charge.

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.

No you don't but personally, I prefer to fully charge it and then drain it twice before I use it.

I refresh at every charge. All it does is drain the battery all the way before it charges. And that is the best way to make batteries last. But there's nothing wrong with just charging up if you need them quickly

I've owned mine for almost a month and use it every week. I always leave 1 of my 2 batteries in the charger between uses so that I always have a fully charged battery. The instruction manual says that's fine and so far, I have not seen any issues with doing so.

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.
