Is there a way to do a "storage charge" with this charger? I've heard it is bad to keep your batteries at a full charge? What should we do?

The idea is do not over charge or discharge any Lipo battery (as well as your cellphone and laptop). Just full charge the battery and shoot tens of rounds, disconnected the batteries and put them in a proper place, then you are good with lipos.

This is a great charger for the price, but it doesn't have a storage mode. Amazon has the small lipo voltage checkers. Buy several. You can set them to go off at 3.7 volts per cell while flying so each cell will be at 3.85 or something close for storage. NEVER DROP INDIVIDUAL CELL VOLTS BELOW 3.0

There is now way to do a "storage charge" with this charger.I think you are thinking about NI-CAD batteries, this charger is intended primarily for LI-PO batteries.

these things are a litte quirky, sometimes I hit the buttons to change from 3 amp to 12 amp and it resets it when it's stuck. Also- if you have time- let it's do it's magic- I think it's conditioning the batteries by taking forever sometimes- end result- it can make old batteries take full charge and extend their life, sometimes mine will take 12 hours to get full charge. If you have the time- I suggest letting it's do it's thing. I call it the jedi mind master charger- who knows how it works- but it works

Re read the manual . There are times you have to put the manual switch on for a few days to charge it to FULL capacity ....especially id you have the second battery attached to it. It always runs down slowly over a coule of months and will not charge if it is not down to @ 75% -80%. Then the manual setting will charge it to full. It may have come to you almost fully charged. Hope that helps. One more thing ..write or call My E they are very helpful w/ any issues.

so when ever i need to charge my AA batteries i should use "Discharge/Refresh" mode? I just bought this charger & i do have the booklet but just want to make sure i am charging my batteries correctly every single time. I am using the eneloop AA.

I had this happen to me. Battery charger did not produce a charge of the battery. I got a new charger and everything works fine. I don't know how you would easily ascertain if the charger is bad except to see that the battery is not charged.

it is a balance charger but if you have a cell that became discharged below minimal voltage then its not going to fix that. However if the battery just got discharged unevenly somehow, it may recharge it to full capacity. I am guessing that the battery developed a short and is probably defective, but trying another charger may fix it (if it was not discharged too far). Just be extra careful when trying to charge that battery and monitor it. Hope this helps you to decide what to do! It is a good little charger for the money!

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.

I think it might be that your battery is dead, LiIon batteries are highly sensitive to overcharge, meaning that they are damaged when you keep your charger connected after it has reached 100% charge. Get a new battery and try to avoid extreme charge states (full discharge and overcharge) are bad for your battery, dont let it fall under 20% and dont chrage it over 95%!! Hope this is helpful

Not sure you really don't want to let li-on batteries discharge completely. It kills their lifespan. It takes about 4-5 hours to charge from 10-15%

Without knowing the state of your battery it would be hard to say. Try the recondition button to see if you can get the battery to work, press the large button until recond light is lit. It takes a while to recondition the battery. Modern battery chargers will not charge bad batteries. If you started with a dead battery, then recondition may help. If the battery was okay then you have a bad unit. I would try it on a good battery before sending it back

The primary problem is that NiMH batteries do not like to be force-fed/overcharged, and that is exactly what NiCd "low-end" chargers do: they are basically constant-current "trickle" chargers (low current, takes many hours to charge, then keep feeding this same charging current even after the NiCd is fully charged). NiCd batteries just shrug off this excess charging current, but it will eventually "cook" your NiMHs. That said, NiMH will pack much more punch into given size...so if you don't leave it on constant charge (drain it, charge it overnight, then unplug it once "properly" charged) it should work quite well. Of course if you ditch the crappy little wallwart "charger" and hook it up to a proper NiMH charger, it'll work Great!

This is not official, since there is no doucmentaion on this subject, but the way i do it, is pull it out, when the battery charger stops its animation (empty, 1/4, 1/2, 3/4, full and repeat) Damn i wish there was more documentation that came with this player. It could've been great. And yes, i already overcharged mine, it only last now for about 4 hours after a day of charging.

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.

The Charger should utilize a trickle charge feature that essentially reduces the amount of charging once the batteries are "Full". So yes, you can leave the batteries plugged in while in storage as I will be doing the same.

I tried to charge my 10440 batteries with the charger and it was not successful. It could be a failure on my part. However, I would buy a charger specifically for the 10440 batteries just to be certain of a proper charge. That's what I did. The charger still charges every other battery I have thrown at it.

Well yea, use a battery charger , or a deep cycle charger with a max of 35 amp .Most deep cycle batteries use a slow charge rate anyway which is a lower amp charger.Just keep the amp below 30 to 35 amp @ 12 volt. This is not a 24 or more system charger.

I read that these batteries, if not used frequently used, tend to go dormant and the chargers will not charge. Need to connect battery to a regular battery charger to re-energize. Recommend you try to charge another battery or investigate the dormant battery issue for your specific equipment. Hope this helps.
