Is it okay to charge the battery after each use? Wahl says to charge it only when it's fully drained. I thought lithiums could handle constant charges

I agree with you about lithium batteries, but I decided to follow their directions. I find I can cut my hair three to four times before it goes dead. If it does go dead I can plug it in and its up and running corded in less than five to ten minutes. Why not charge it after every other hair cut?

I actually don't know. Here's why. Almost everytime I use it I store it in the charger so it charges after each use. On occasion while traveling I've used it maybe five times without charging and it's held the charge through that and when I did charge it after that use, I never noticed how long it took. The shaver doesn't tell you how much of the battery is left before it needs to be charged. I guess they assume you'll store and charge it after each use.

I charged it as normal. I pretty much use it until it reaches around 20% battery life. I also keep my phone plugged in most of the time when under heavy use.

That is a great question. I really haven't noticed it being drained too much after no use. To be honest, I haven't really tested that too much. I think mine is dead right now. I would think it's like every other battery and it will lose some charge after no use. Just don't know how much.Regardless, it's a great device and I love it. It's saved me several times.

I had issues with my battery because I kept it charged when not in use. I found out you should NOT keep it charged; rather keep it in the vac until it dies and then recharge, this will extend the life of the battery. I bought a new battery and that solved my problem. Good luck.

i am in my 3rd season of ownership of the mower and battery, and both are still going strong - but i do have a major word of caution. The manual says to keep the battery charging when not in use and during the off-season and they damn well mean it! i had bought a spare battery 3 yrs ago also and was nonchalant in the off season and left it unplugged ; the next spring i went to use it and it was utterly dead and would not take or keep a charge. keep it in the charger at all times and you should be good for several years

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.

Lithium batteries cannot be overcharged - part of their design must include a charge controller for safety, so lithium battery chargers (cell phones, screwdrivers, shavers, etc. alike) will always shut off when completed. To know if it's done charging without an indicator, feel the wall-wart power supply - it'll be cool if it's done charging.

No just use it until the lights go out then recharge, it's an ion battery, so it's best to drain it then charge to full.Love mine it have saved me a ton of headaches.

Have had my Schumacher [10+] years, and very rarely use the 'Manual' setting because: Manual setting pumps out a full charge, even, after the battery is finished charging. If left to continue, it will hurt the battery. Whereas the 'Automatic' setting will charge in increments, first full charge, than steps down to half charge, then again at about 80% battery capacity, than, steps down to a small charge to top off and finish the charging cycle. 'Automatic' setting, hook it up and let it charge overnight, 'Manual' charge, be very watchful during the whole process, or risk damage. Secondly, if your battery is not holding a charge, it may be time for a new one, and don't think just because the new battery is new, means it's good - I went through 3 replacements of [so called Premium] batteries from Wal-Mart before I finally got one that wasn't crap, better still, don't buy a battery from Wal-Mart, *no matter what they claim*. Wal-Mart batteries even with a name brand badge, are not the same, because, they are built for Wal-Mart, to Wal-Marts specifications, and that usually means, to cheaper standards. [12/2013]

I never thought about this. I keep my batteries charging all the time. I haven't noticed a problem. Yet, that is. Christine S may have a good suggestion.

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.

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.

You should always allow a Lithium Ion battery to fully charge before use. Overnight is best.

The LIPO batteries these use need to be used correctly, including the way you charge, discharge, and store them. With each flight, you need to stop using the battery BEFORE it gets too close to being completely drained. The battery must be stored with at least a certain amount of charge in it, and you should check the batteries every week or two to make sure they still have at least the minimum charge. If you discharge these too far, they can never get back to their full potential, and will continue to get weaker and weaker the more you over-discharge them. Go google it for more info.

If I were to guess I would say you put it back in the charger after each use. That destroys ni-cad batteries. If you cannot replace the batteries (and then only put them back in the charger when the unit is dead or almost dead) do so, otherwise, you have just been educated on what they call ni-cad memory and why you should get lithium batteries if possible. I have had mine for about six months and I have not yet needed to recharge it and I use it almost daily.

If you use it as a stand-alone, charge it after each use. I like a float charger, leave it plugged in all the time, no damage. Simple trickle chargers can shorten their life.
