E5-576G Battery Replacement and Life Does this battery life of not even two hours

I've had this laptop since 2019. So far, it's the best one I've ever used and I want to continue using it for several more years. The battery, however, reached a point where it no longer lasted much more than about an hour under heavy use. I purchased a genuine Acer replacement battery and installed it yesterday. It was actually an easy process and only took about 15 minutes. I was looking forward to not having to keep it plugged in while toting my charger around with me everywhere I went.

To see how the battery held up, I did my usual heavy routine of web browsing, emailing, editing and organizing photos, and recording audio files with the Audacity app.

I didn't notice much of a change. Within two hours, I had to go get my charger — and that was after the laptop unceremoniously shut off with no low battery warnings whatsoever. (I'm thinking that was due to my power settings getting mucked up somehow, but it was still annoying.)

Does this battery life of not even two hours sound right for such heavy use? I don't expect it to last 7-8 hours, but I was hoping for at least 4-5.

Maybe I had become so accustomed to just keeping the laptop plugged in due to the old battery that I have forgotten what "normal" battery life is?

Any thoughts?

I should also mention that I since I was doing this laptop "surgery" and changing out the battery, I added an additional 8G of RAM in the empty slot…if that matters…

Hi @GenXrail how many watts is your battery?

It is difficult to estimate the duration of the batteries because it depends on several factors such as type of screen, brightness, disk, memories, Wi-Fi, processor, use of the fan, etc.

I leave you the estimated times that appear in the service manual but keep in mind that they are times based on a minimum use of the equipment, that is, an intermittent use of the equipment where you close the lid to suspend for periods and reopen it, for a continuous use these times are much lower.

The service manual indicates that the equipment, depending on the type of screen, incorporates 41 or 62 Wh batteries and their estimated duration:

Thank you.
All the best.

New battery is 63 watts.

I've seen some posts about doing a battery reset, but the times for the reset are not consistent. One post said hold the reset button down with a paper clip for 4 seconds. Another one said 5 seconds. Another one said 20 seconds. Yet another said 30 seconds.

Who is correct?

Or would a battery reset even be necessary or helpful?

Just in addition to all the above and some more information for you in regards to laptop batteries and what I’ve found over the years, the PRO Laptop Battery Analyzer is a tool that can be used to diagnose, revive/wake up, charge, discharge, calibrate, reset the chip or measure the real capacity of almost all laptop batteries on the market. The ultimate Chip Reset function converts the NLBA1 device into a professional tool to repair laptop batteries.

Have a look at the video of how the PRO Laptop battery Analyzer works (btw I'm not getting anything for this and I'm not sponsored by PRO Laptop Battery Analyzer).

With laptops and if you calibrate your battery regularly from new then it should last quite a long time, battery life depends on how you use your laptop, if you use the laptop on battery only the battery life is less than a battery that is constantly plugged into a charger and used like a laptop and its regularly calibrated,

Laptop batteries have cells that cycle with the laptop charging circuitries, if the main cells are depleted then the battery turns off and the battery doesn't charge and needs replacing, same if there are any shortages within the battery or the laptop and the battery gets hot, the battery has a soldered fuse link that melt at a certain temperature and turns the battery off completely, also batteries that have not charged and were left for long periods of time also get to such a low voltage state that they turn off and need rejuvenating.

Have a look at what is involved and what tools a proper technician uses to evaluate a laptop battery and how he rejuvenates a battery that has turned off here ”Can we fix some laptop batteries just by charging the cells? YES !!!”

@StevenGen the battery is new, I think that this battery should last between 2 and 4 hours, 2 hours in intense use would be correct.

All the best.

Battery stats of your BIOS and Windows are incorrect if you did not do a full battery charge cycle with the new battery: Charge to 100% till the amber charge LED turns blue, let it charge another 30 minutes and unplug the adapter. Use your laptop till it turns off (goes in hibernation) plug-in the adapter and repeat the charging process. Run a battery report in Windows and see what the full charge capacity and remaining hours are.

I didn't do that exact charging regimen, but I figure it's close enough. Trying to figure out how to run a battery report was confusing so I gave up.

Unless that report can give me longer battery life, I'm not going to bother.

So far, this seems to be an exercise in futility. After almost a week, I still notice very little increase in battery life and that's just for normal browsing and emailing (without a heavier duty cycle with photos and audio files.) At least I'm only out about $30 and 20 minutes I spent installing.

A Windows battery report is the diagnosis of the condition (health) of your battery and should be the deciding factor to replace your battery or not, like doing a physical check-up with your doctor.

I understand that — and was able to figure out how to generate a report — but it doesn't do me any good if I can't interpret what I'm looking at. I see graphs and battery capacities, but don't know what to do with the information — and I consider myself to be reasonably good with technology. I'm probably overthinking this, but that's normal for me.

No problem. Check what the latest full charge (100%) capacity is of the battery. If that is way lower than the initial or Design capacity you have an issue as a new battery should have the same capacity (no wear the first 6 months). At the end it will give you an estimate how many hours a full charge will last.
