Why does this charger reset after inserting some batteries?

Well, my experience is that each slot operates on it's own. Given slots 1, 2, 3, and 4. I insert a battery in slot 1, accept "Charge" as the mode, go to 800 mamp, accept that, and put a battery in slot 2. Slot 2 then lets you select the charging mode (charge, break-in, refresh, discharge) but slot 1 setting should not be affected. I just tried it with 3 batteries and experienced no problems. One thing to consider is this. By accepting, you press "Enter". For charging, you press "Enter" for charging, then set the charge rate with the up and down arrows. Then, you have to press "Enter" again for the charging rate. It may look like you had chosen the charging rate by pressing the up and down arrows, but to complete the setting, you have to press "Enter" again. I don't know if that's your issue, but that's my best guess.

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, don´t let it fall under 20% and don´t chrage it over 95%!! Hope this is helpful

Because two batteries charge at close to the same rate, and are not identical in their depletion, the charger stops charging the first battery that's full, charging only the one battery that's left. Sounds like it should be able to do only one.

I'd suggest removing the batteries and then reinserting them and see if it resets. If not, then I think you might as well throw it away. I sent an Email to the manufacturer once about a problem I was having and they didn't respond.

Try moving both batteries to the other side of the charger. If you had them on opposite sides or in the middle I believe the left side as you face it plugged in is the side to use for less than four batteries.

You should traid it out and dont leave your batteries on the charger after they are fully charged.

I have a problem, that might be related and I wanted to ask people as well. When I put the battery in the charger (I have two), most of the time, even though the battery is empty, the charger shows green light and does not charge. I have to put the battery in slightly elevated angle and push on it and then it will start charging. So maybe your batteries were not charged at first place. Also happens to me, that the batteries discharge if not in use for 2-3 days, so before use I always recharge.

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!

Good Question: The only time that you have to re-enter the battery type is when there is no power applied to the charger (either battery, or the 110Volt wall plug) So if it has either type of power applied it remembers.

have the same thing but not the same problem. They unfortunately (charger) do wear out from repeated use. Not that well made but usually work fine for quite a few charges. Don't know why it won't charge all your batteries as mine only cares if it is the right kind no matter who makes it. It could be the battery is bad if your charger works on other batteries.

Haven't had this problem myself. Try taking the batteries out for a few mins then reinsert and see if that will reset the unit.

Hi Donald, The charger cycles back on when the battery looses power. When charge builds back up the charger cycles off.

I've had this happen occasionally with mine, particularly as the battery has gotten older. It seems to happen only after it has been plugged in for a long time. Unplugging it and letting it sit seems to clear it. If I don't leave it plugged into the charger for more than a day, I don't see the problem. If your's always does it, I think the battery may be getting sick, or the charging circuit is defective.

I failed to fully charge batteries before I started using it and it of course quit working. I went to battery place to try to find the batteries or see if they would even take a charge. They wouldn't at the store but when I tried them again on the charger that was provided, they charged up again. It is now working again.

I had this happen to me also. I had a completely dead battery in my car when I attached the charger. I turned the key on and tried the headlights after charging for only a few minutes to check if anything was happening. The charger started clicking and cycling on and off. The noise stopped after a few minutes and it continued to charge fine after that. I believe the cycling is an overload protection. If you experience this try charging the battery while it is disconnected.

First use NEW batteries. I thought my so-called NEW batteries were fresh and up to charge. They were not! Get a battery tester. Once I had batteries that had a full charge It started without having to do it manually. I do not manually do it any different than the other six answers in any major aspect. I had to start it manually until I realized that I had new batteries that did not have a full charge. Now it works fine without having to resort to manual operation.

Mine had issues until I put fresh batteries in it. They weren't old, and I didn't think they needed changed but it worked. If that doesn't work, try the reset button.
