Replacing my Asus Zenbook UX21A battery

(This review was originally posted to Amazon as my review of the Green Cell C23-UX21 replacement battery was rejected by Amazon. Possibly because I used the word knackered ? Anyway, this was the review….. hope someone finds this useful.)

My 6 year old Zenbook’s battery was completely knackered by Spring of 2019 (I would get less than 5 minutes once it was unplugged from the charger), and so I bit the bullet and bought a Star LabTop MkIII (which I am very happy with by the way).

However, it did irk me that one of the most beautiful laptops I had ever owned was sitting in my study gathering dust. A few months back, on a holiday where I was attempting to edit photos on the go (using a tablet and phone), I wondered if I could resurrect the battery and take the old laptop with me.

I found an iFixIt article which explained how to replace the battery in a UX21E, and another article which explained that the UX21E and UX21A were identically constructed. On the basis of that I ordered the Green Cell C23-UX21 Laptop Battery.

You will need:

• iFixit Opening Tools (or cocktail sticks which I used);
• Phillips #1 Screwdriver
• T4 Torx Screwdriver

The iFixIt instructions worked perfectly, and within 30 minutes I had a fully functioning Zenbook again. I took the opportunity to replace my ageing Ubuntu 18.04 with Linux Mint 19.2 Mate and my sleek laptop is back up and functional, ready for our next trip abroad.

The Green Cell battery seems to be holding up OK but I haven’t used the laptop in anger yet. I will update this post once I get some more experience with it.
