Acer E5 575G 50PY How to recognize a genuine Acer battery and other questions?

greatyu

There have been a lot of counterfeit merchandise floating in the market these days, due to the pandemic the official authorized vendors sometimes sell fake products. I have to buy a new battery because the older one I think is fake. I got this from an authorized seller too. My previous battery lasted at least 3 years while this one just lasted 7 months or so. I also know how to self care for a laptop battery so I don't think its the issue.  I have 3 questions, if anyone would please answer. I will be really grateful. 

Laptop model: Acer E5 575G 50PY,
Laptop battery model: AS16A5K ,Li-ion Voltage : 14.8V Capacity : 2800mAh/41.4WH

1. How do I recognize a genuine Acer laptop battery? 
To my understanding the genuine batteries have a serial number, QR Code and manufactured date. also the warranties? Genuine battery has a minimum 1 year manufacture warranty? The counterfeit product had just 6 months i think. 

2. How do I exactly calibrate a new battery? 
I have seen several posts here, but what exactly is the correct way? Does it differ with battery models or laptops? If so what is the correct way to calibrate to get the full efficiency of the battery for my model? 

3. Can a faulty battery affect the keyboard as well? 
I am not a tech pro, so I had to ask this. I've been having keyboard issues where when i press one key it types double sometimes. The whole thing started after I replaced the battery. Wanted to get the issue solved but couldn't go to the service center due to long periods of lockdown. 

I think I have definitely asked more than 3 questions lmao, but I hope someone can help me. 
Thank you so much!

(1) ACER may re-label batteries made by Samsung, LG, Panasonic and a few others but doesn't usually manufacture them. So genuine doesn't mean too much. You usually pay a bit extra for the ACER label and the ACER part no. but doesn't necessarily mean they are any better or any worse than no-name or other brand name batteries. You should buy batteries from and trust a reputable battery vendor.

2) To calibrate meter, simply charge battery till battery charge LED turns from steady orange to steady blue. Then remove charger and allow the battery to drain till the Windows low battery warning appears. Usually between 7-10%. Then plug charger back in. Allow battery to fully charge to steady blue battery charge LED. Meter should between 95-100%

(3) A faulty battery, especially if internally shorted, can affect many peripherals including overheating and a fire hazard. It should be replaced.

You can check the condition of your battery by going to the elevated command prompt.  Enter 'powercfg /batteryreport'. Then return to the desktop. Open file explorer. Then search for' battery-report.html' in the c:\windows\system32\ sub-folder. Double-click to open it in the browser. Post screenshot of the first part of the report if possible that compares design full charge capacity with its remaining full charge capacity. It may also reveal the battery manufacturer.

Hi thank you so much for the response it explains a lot actually and i got many information which is useful. 
I have already generated the battery report using the command prompt but I was still suspicious anyways. 



It is sad that still it's difficult to distinguish what is genuine and what is not in the market, I got the battery from the authorized seller of the Acer brand here, maybe it's the model of the battery. The previous battery was Panasonic, so maybe I will go for that from another vendor. I did watch some videos and learnt that the genuine batteries contain that white sticker with the QR Code and etc (which was actually present with the panasonic one) but not with the LGC i currently use so I did think that is the cause. 

Should I calibrate the battery like that for a few months doing that? Because I read here that it should be done a few months also. 

 And i'll try changing the battery and see if it resolves the keyboard issues. 

Anyways thank you very much for the info!

The LGC AS16A series batteries are typically used in your laptop from the factory. So it should be considered 'genuine' from your viewpoint. While It seems to have lost more than 50% of its original design energy capacity,  it might actually regain some of this original energy storage capacity by cycling it a few times (exactly as if you're calibrating the battery meter)  if you usually leave it plugged in all the time. Cycling/calibrating is easy to do so doing it regularly might be helpful.

I tried cycling it, the computer just shuts completely off after reaching 50%, so I don't think its possible? it happened a several times unfortunately. So I can't use it anymore sadly. I tried resetting and reseating the battery but nope. I remember the previous one had more backup time of like 4-5 hours, while this one from the start it only had like 2 or 1 hour. And even with the half of the life gone of the Panasonic one, i was able to use it for an extra year tbh.

>>>I tried cycling it, the computer just shuts completely off after reaching 50%>>>this one from the start it only had like 2 or 1 hour>>>

If Windows gave no low battery warning before it shuts off, then yes the battery's own internal charge controller is defective. It sounds like you bought a defective battery right from the start that should've been immediately returned to the vendor before its return defective merchandise authorization period expired. Usually only a few weeks for most vendors.

Any battery manufacturer can have defective merchandise. So you should only buy from a vendor/seller that you trust and that has a good returns policy if you get a defective battery..

Thank you this seems to be the problem to be honest, I should have returned it but alas lockdowns of course anyways. I do not have much experience with laptops and its batteries because I was a PC person and i didn't think I would receive a defective one because they are the authorized sellers of the Acer brand but now I know, so thank you very much!

Yes, the chance of getting a bad battery from an authorized vendor is small. But still not zero.
