Disable battery charging?

[shaun166]

Hi guys,

Is there any software that can disable acer's battery charging when you plug in charger?

Hi shaun166,

Why do you want to do that? The software is for reporting the state of charge of the battery, but not for enabling/disabling the charging of it when the adaptor is plugged in.

I was wondering if my battery is charged 100% and i still plugging the adapter will have any bad effect to my battery?

If left for extended periods of time, yes, it will damage the battery. Some will say this isn't true, but I run a computer repair service, and I see it all the time.

If your laptop is going to stay plugged in, remove the battery. BUT, periodically use the battery until it is fully depleted and then recharge it.

i think when the battery charged fully 100% the adapter will not be charger again.
logically the case same like charger handphone.

 

[dewking]

well the chip suppose to block the charging when the battery is full. HOWever, think again, the charging will never reach 100% as times goes by.

As recommended MacGyvr, do take out the battery when it is not used. But periodically(lets say 1-2months), deplete it completely and then recharge.

It works for my friends. I regretted I didnt do it and the battery died in less than 13 months..=(

built in battery

Hi everyone and sorry to bring this up again, but, how would someone be supposed to do IF the battery is built in (acer 5830tg)? Wouldn't want to damage it without cause, but then again, I'd really need to use the laptop for extended periods of time -.-

I wish the misleading info wasn't posted for this topic. Anyway, the battery does not charge once it is reaches 100%. It's been this way for many years now. There is no harm to leaving the battery in while the laptop is docked or on an AC power source. It is a good idea to drain the battery every so often, and then give it a full recharge, just to maintain it's life, but even that is not as curcial as it once was, due to advancements in battery quality and technology.

If you ask anyone who works in corporate IT (not a little repair shop), they will tell you that battery failure rates don't change for laptops that are used often on battery as compared to ones that stay cozy in their dock on AC power all the time.

Give experience with one battery for an individual is not much of a sample size to go on. A battery can die in 13 months regardless of how you use them. That's why the typically come with only a one year warranty. I have 30+ laptops in my organization, some are used on AC power 99% of the time, and others see a good mix. The failure rates of the batteries (all identical, in identical laptops) doesn't change based on the usage.

I see. Thank you! But then is the "disabling battery through bios/software/whatever" rumor made up either? One last thing if I may (And I already know it'll sound stupid but I had only used desktops up to now). If an integrated battery happily dies, then the whole laptop is to be trashed? Seeing also the one year warranty.

 

[DeaconFrost]

I don't know about it being a rumor or not, but I've never come across software to disable the battery when charging. That's all done in hardware, much like your cell phone charger. When the battery is full, it shuts off. Think about a gas pump. When your car is full, it clicks off. The computer isn't using the battery when plugged in, so it's a moot point regardless.

Integrated batteries are a dumb idea, and should be avoided. I'm learning this with my crap iPhone 3GS. It will be the last phone I buy with an integrated battery. The most likely piece of hardare to fail in a laptop is the battery.

 

[icedcoffee]

Yeah, same for me. Now I'll just have to divert my thoughts from the idea of the battery stealing away from me my whole pc >< Thank you for the explanation anyways. Been wondering about this for some time.

 

[roise0r]

I thought that even though there is a chip that blocks a fully-charged battery from being charged further, having a laptop on AC all the time will still damage your battery, since the battery will drain just a bit every so often and that bit is enough for the chip to allow charging again. so you end up using the battery 1%, then recharging that 1% and then using it again and recharging it again and so on... (which is bad... I think)

Settings to charge battery automatically, is it possible? - see my post!

 

[jcgriff2]

I would leave the system alone as-is. You're liable to do more harm than good.

The laptop I'm on right now is 3 years old and has the original battery; been plugged in (A/C) most of its life and still can last 2+ hours on battery playing a video.

Another laptop here is the same age, yet the battery holds ~10 minute charge.

The real area of concern is the connection where the A/C adapter plugs into your laptop. The "pin" on many laptops is soldered to the mobo and loosens or breaks off. Be careful when plugging/ unplugging or moving around when the laptop is plugged in.

 

[rraod]

The battery's life will more or less remain same whether you plug in the AC adapter all the time or not. Most batteries will give good life inspite of being connected to AC all the time. Only few defective ones will give in sooner.

If it is true that the battery gets damaged left inside the laptop with AC connected, the manufacturer would have provided a separate switch to isolate the battery from laptop.

I think people should stop worrying :shock: about batteries and start enjoying the laptops.

 

[JourneyAbout]

Well, they might not include a switch because then they can sell you a replacement battery for $90.

My new Dell XPS L502x has Dell Battery Meter software which allows you to turn off battery charging until the system is rebooted.

Just like your camera batteries...you don't have to actually use them for discharge to occur....they will constantly be discharging while sitting there doing nothing. As stated above, your system will be constantly topping off the battery. I believe a charge cycle is a charge cycle whether you are topping off 3% or 93%.

Batteries are my speciality having/being an Rc car racer, airsofter and various other intrests involving a lot of battery guff.

When it comes to laptops i always advise to cycle batteries, from fully charged to almost flat, and then place one charge again.
I will never leave one on charge for extended periods of time with the battery in place.

Yes its true that Li-ion batteries do not suffer from battery memory, and can be charged from an state of charge, BUT they do have a life time charge limit. Be it 1000+ charges and then you may see a deterioration.

Li-ion do have very slow self discharge, so most would assume a fully charged battery will stay so, meaning the laptop will stop charging it.
However a charger will never charge the battery to 100% and the treshold for charging or not charging maybe minimal, so any discharge will result in a small and brief charge back to that threshold.

I have proved this point with many experiments and seen the effects on laptops that I fix.
The last proof I had was a laptop I bought and owned for 2 years, and then sold to my dad. At the end of my ownership the battery would still last around 3 hours.
After owning it 6month and my dad leaving it on constant charge it would hold about 10mins, and now less than 20seconds lol.

Through not to careful cycling, I can still squeeze 6-8 hours out of my macbook a year after I purchased it, and that's still on par with it being brand new.
That's the badgers guide to health laptops lol

If you do NOT use a battery for a long time it is best to store it in a fridge at about 65% charged.
Samsung charges the battery in their laptops to only 80% and keeps it there. A higher charge is not possible when the battery is in the laptop. It increases the life time of the battery.
It is best not to charge the battery till it is really necessary since the number of charging cycles determines its lifetime. So it's counterproductive to charge a battery each time you get a chance and then have to continue running the laptop on the battery because you are going out again with the laptop, only a few minutes after charging. But who knows beforehand how long a power socket will be unavailable or how long you will need the battery?
These are optimum conditions ............ but who can stick to those?

 

[Solidwave]

All modern laptops use lithium-ion batteries. Li-ion batteries will explode if overcharged. Every laptop has a charge controller that will stop charging the battery when it is full so the battery won't explode.

Li-ion batteries are rated for a specified number of complete charge-discharge cycles. Intentional discharge cycles will reduce the life of a li-ion battery.

Only nickel-cadmium batteries need occasional complete discharging to maintain their performance. Ni-Cd batteries haven't been used in laptops for around two decades now.

I realize that this particular subject matter is old but after scratching my head, pulling my hair out, going through all the different solutions, including in the BIOS, I used a little common sense and checked the connection between my power cord and the adapter. It looked and felt like it was a solid connection but I pulled apart the connection and reconnected; problem solved. This was, in my case, the solution. It may not be the solution for others.
