Would like to know how to properly discharge once the battery is fully charged 4-5 time for best performance ?

You should not fully discharge a Lithium Ion battery. Unlike Nickel-Cadmium batteries, this will negatively affect a Lithium Ion battery. I have a feeling they copied and pasted that information from an older Nickel-Cadmium battery.

This is a Lithium Ion battery. Fully discharging will not improve performance (capacity). That only worked for NiCad cells. Fully charging before the first use is always recommended.

Best to turn it off then charge it....don't let battery drain totally. I often use it plugged in when it's fully charged.

I'd look in the manual for something saying "It will not overcharge if left plugged in". If you can't find such, then I'd plug it in and check the voltage on the battery every hour for 4-6 hours. If the voltage never goes above ~14.5V everything's fine, but if you see 15V or higher then you're "overcharging" and want to pull the plug.Another option to consider if you like the idea of keeping it "freshly charged" would be to put it on a timer that comes on for 15-30 minutes each day, but isn't on 24/7.

5 hours sounds about right when the battery has been fully drained. Usually I just plug it in before I go to sleep at night and when I wake up it is fully charged.

Get a temperature compensated battery maintainer. Your battery will last longer and you will use less juice at the plug.

Is it possible the battery is not charged? The instructions suggest it is necessary to discharge fully then recharge. It may be it came discharged, and must be on charge to be recognized, I bought an inexpensive battery and it lasted about three days, then began indicating it should be replaced. The only other possibility would be an incorrect battery? Best regards, Sammy

Yajvendra, I can't give a good answer. I place batteries of different states of discharge in the charger and go about my business. When I get home a 4-5 hours later, they're charged. I don't know at what point they've each reached their charged state.

I've gone from completely empty, to fully charged in about 3.5 to 4hrs. Hope this helps.

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.

That is what we did and battery would not charge after only a few months. I do not know if letting it completely discharge before recharging and not storing it in its built-in storage bracket will help. Electrolux is absolutely no help with this, nor with replacement parts or service.

After fully charging the battery, let it run down until the battery life shows red then put it to fully charge again.

I would expect a few hours for a full charge. What indicators do you have of battery level? There are indicators on the bottom of many packs. Push the button and see how many lights show. Also, if you are using your computer heavily with screen at full brightness, a lot of the juice will go into running the laptop. There won't be much left to recharge the battery. You might try putting it aside to sleep for an hour and checking back later. Of course, if the battery is bad or the calibration is way off, that is another thing. If you charge a sleeping computer all night and only get 30 minutes of use before it's dead again, that's not good. There are ways to address that but someone else may know off the top of their head.

The greater the battery is discharged, the longer the charger will take to restore it to full charge. The unit will automatically do this and maintain a trickle charge until disconnected.

had the same problem at first but I discharged it completely then left it on changer overnight, about 4 hours more past the light turning green. Now it holds a charge long enough for 2 trims. DO NOT leave it on charge any longer than that.

A fully discharged battery will typically take between 20-30 min to recharge fully in my experience. Longer if the battery is hot when it is placed on the charger.

I would charge the battery first. I believe those are the instructions anyway. In fact, I believe there are specific charging procedures initially to get the best life out of the battery. If you continue to experience issues, I would contact the vendor/manufacturer.

I had the same thing happen. Unplug and use system to deplete power and then recharge. May take a couple uses but mine bounced right back and recharges fine now. Also holds a longer charge now. The more you use it, the better it seems to perform.
