Where to get High Quality Replacement Laptop Batteries?

I have an Asus K53E Laptop purchased in Dec 2011 and the original battery is capacity is dropped from 59,400 mWh to 50,006 mWh on a full charge using a Win 10 Powershell command. I am looking to get a replacement battery from a reputable company. I see many sellers on Ebay and Amazon with varying levels of reviews. I was hoping someone could suggest a vendor that they have had a good experience with their battery replacements. I have attached the specs of the battery that I am looking for.

Any suggestions would be helpful.

Thanks

With the stated capacity loss, you are way more likely to do WORSE with a replacement battery. I would leave it alone.

So it's dropped about 10% in nearly 10 years. There's nothing wrong with your battery, in fact it's performing better than most.

I updated the numbers based on the recent test and is more like a 16% loss. Still, that is not too bad given the age. That being said, the laptop runs on AC most of the time and only on battery occasionally as it is always plugged in.

That's amazing battery life over a decade, most batteries would be running for minutes after that long.

It likely helped that it doesn't have many cycles on it, but leaving a battery plugged in and fully charged doesn't help it either. Unless you do what I did back when laptops had removable batteries: remove the battery when the laptop was left plugged in for an extended period.

In my experience, the best quality replacement batteries are the OEM ones, followed by DIY rebuilt batteries if you pick your own cells. Otherwise, there tends to always be a catch, either you get lower capacity than advertised and/or the batteries degrade rather quickly. Worst case you get dangerous cells that explode.

If you want OEM consistency, go an OEM battery from the manufacturer. The only downside is who knows how long the last time these were made and how good will they be after you get one in your hands.

Thanks for the suggestions. The battery does not have many cycles as you mentioned, and the Asus charger/computer firmware does not overcharge the battery either. I think I may just keep using what I have now till the runtime is really poor. At that time, even a replacement battery will be better than a severely depleted one.

Oh! Forgot about them, heard good things as well. I was going to drop off my old battery one time, but settled on a cheap ebay replacement that worked okay and didn't explode.
