Hey there technical people,
As we all know, lithium batteries have a habit to rapidly deteriorate after around 2 years of usage.
Before I got the idea to make this video, I removed a swollen bad battery from this 4-year old Dell Latitude E7470 laptop.
I made a mistake and threw out the bad battery together with the attached cable.
I had to order new cable online. Its not so cheap but I got it rather quickly.
This is a standard 55watt replacement battery. It connects to the motherboard with a single wire and its held by 3 small screws.
After a while of using this, I think this battery actually outperforms the original one from Dell!
I can once again use my laptop for hours on the go.
If your battery is old, fat and tired, just get a new one and give it a nice long charge after unboxing.
I put product links and coupon code into video description. It will save you time and money.
