Battery Charging Question

Hey guys, does anybody know if having my battery in my laptop would decrease its life even though I have the lappy plugged into the well supply?

Should I remove it whilst i am not out and about ?
 
I think it does decrease life, or in my mates case it caught fire. I never leave my laptop or anything infact on charge.
 
I'll just have to keep an eye on it then in Aida64 .

Aida is currently telling me this and its brand new.. The wear level is a little worrying for a brand spanking new 9 cell battery...

 
If it's a lithium (which I'd hope it is these days), charge it up to about 70% ~ 80% then take it out and put it somewhere safe. (i.e a drawer somewhere dark and not warm) keep it at room temp or below and it should last a lot longer than keeping it plugged in and trickle topping up. This can kill those kinds of cells, and in some rare cases, cause catastrophic failure (a.k.a ASPLOSHUN)

Edit:You posted before I did yeah, charge to around that level and store it. Best thing you can do for a Li-Ion battery if you're not actively using it.
 
I think it could loose it's performance quick as well if not taking it off charge. I find that with mobiles, they last forever but if I leave them on charge over night, they drop in battery % a lot quicker.

It'll also be eating away at your electric, costing you more money.
 
If you plan on keeping your laptop plugged in and using it as a (temporary) desktop replacement, you could always pull the battery out and just not worry about it.
 
Temporary ??

Nope this is actually a full time desktop replacement, I had to flog my desktop to buy this as I couldnt fund a lappy for an upcoming course that Im going on...

Maybe in 6 months or so when the funds are coming back in then i'll start another desktop build....

Oh yeah, I remember you posting that somewhere! Tough times :(

In that case I'd personally just pull the battery out. Can't destroy what isn't there ;)
 
I've always just left my battery in, with it on charge pretty much all the time.

Afaik - Most laptops (and other devices) have complete shut off now, so if the battery is fully charged and plugged in, it will just switch to the mains power and not touch the battery.

I've never had any issues with battery life with any of my devices from doing this tbh
 
This is the case with phones (and tablets etc) that use Li-Ion batteries. They charge until 100% and then stop.

This guy explains it really well:
0:50



I'm assuming that when phones and tablets can do this, a laptop does too?
 
So seems like I can keep it in there then according to the youtube vid ,, will be closely monitoring aida64 and will keep you guys informed..

Having it plugged in will also save me from loss of power due to power cuts which are quite commom during the summer months here due to stormy weather...

Thanks for the input dudes :)
 
Cheers for the video, I've noticed it does go down to 97% especially with my iPad. I don't believe that it doesn't need a full charge the first time you use it though, don't see why a manufacturer would list that in their manual if it wasn't true.

He explains that at the end of the video. This used to be the case with the nickle(?) based batteries back in the day. Going off-topic here, but mind telling me in what manual you found this? I'm quite curious now :)

Just bought batterymon from passmark to keep an eye on whats going on...

Nice! Keep us updated please! :D
 
Well my most recent one is from the Sony Xperia Z, that manual says to charge it for 30mins before use.

My Galaxy S3 I think just said fully charge before use.

I don't think Apple say it in the manuals for my iPhones/iPad/iPod but there manual is pretty simple, just shows how to use it basically.
 
As they charge they form crystals and lose some capacity normally ~20% but by then you will likely getting a new laptop, phone etc, lots of little charges are much better for the battery, e.g charging from 50% to 100% is better than 10% to 100%.

Once charged they stop the battery then drops to around 95% and then back to 100 this is why sometimes you unplug and it drops ~5% very quickly.
 
I know these videos say this stuff, but for my own peace of mind. Especially with lithium batteries, i'd 80% charge it (this is called a storage level charge) and I'd put it somewhere safe.

If you're never going to use it, this really is best practice, I wouldn't chuck away caution on one video.

I handle a lot of Li-Poly batteries in airsoft, which while slightly different, have exactly the same kind of discharge stuff.

The issue with leaving something fully charged and plugged in all the time is, it will always use something from it and it will always top that up. That will degrade it over time regardless.

As far as Phone charging... I find the batteries that come with them should always be 100% charged on first use, otherwise you can/will ruin the battery. Then after a week or two of successive use-all-day charge-all-night cycles the battery will start to wear in and become better at holding the charge... I don't know the specifics of why this is, but I've noticed it on nearly every new phone.

I've found best practice for phone usage is charge it nightly, then once every 2 weeks ~ month (depending on your schedule) completely 100% discharge and let it die, then do a full recharge without using it. This keeps the battery calibrated properly and on it's best cycle rate.

Lithium batteries do have a limited number of recharge cycles before they become useless/degrade/become dangerous but the lifecycle of replacements is so fast these days that the spec is kind of redundant.
 
That's worth asking about, I personally charge my phone at like 70% everyday, by the time I go to bed but some people say it's better for your battery if you let it loose it's charge to a few percent then charge.

But then I see people (it's always girls) saying iPhone batteries are crap...no they arn't, they're the best I've ever seen in a mobile device!

Didn't know you were an Airsofter SuB, always want to get into it but never do. Can't get my head around UKARA, frustrating if you're just starting out.
 
Practices above have given me best results.

The only people moaning about battery life on iPhones are those that have it on 100% brightness, with wi-fi, bluetooth and all the other crap turned on 24/7... They seem to forget these things require POWER to do this.

Yes mate, I opened the First purpose built indoor arena in the UK 4 years back, since been sold on. But yeah, consider me a collector of things that shoot around 325FPS and up ;)

As for UKARA it's a piece of cake mate, be 18, find a UKARA reg'd site to play at, go and have a game and see if you like it. If you do sign up and pay for the membership fee (usually around £35~£50 depending on how self righteous they are). Continue to play at the site for a minimum of 3 times, rent their gear to help with with costs (it's not a very profitable hobby for people running it), in not less than 2 months.

(The key thing here is, you have to play 3 times or more, and you have to wait for 2 months, you can't go 3 times in 1 month and get it. These are guidelines for the site to make sure you're responsible and not just some kid after shooty shooties who'l get arrested/shot by the police (who shoot first and ask questions late when you point a R.I.F. at them). If you're responsible, some sites will let you have your stamps early.. totally depends on the place you go.

Get a UKARA form from UKARA website, fill it in, get your 3 site stamps from your local site.

Send form to a retailer along with your order (easier to pop in) and then you can buy R.I.F.s.

If you're not bothered about high-vis blue/green/pink/orange on your gun, you can buy these so long as you're 18+. but if you're into airsoft, you want a proper R.I.F.

MASSIVE KEY POINT. if you buy a gun that's been two-toned and you paint over the bright colour AT ALL you are 100% breaking the law and can/will be kicked off most sites.
