It's a shame that I don't live anywhere near Hull (or can get to Hull) because someone is offering 2x laptop batteries for an Acer laptop, for just £5:

At that price, it'd be worth it to just take them apart and salvage the cells! One of the cells I tested recently (from an old HP laptop battery) clocked in at over 2100mAh, so there's often plenty of life left in old laptop batteries!
And even better...

£2 for 2 laptop batteries? That's dirt cheap, it's worth it for the 18650 cells inside!

I could buy you them as a gift and I wouldn't even charge you for postage!
eriously, life's too short to be worried about retards on an internet forum.

@princechromey Moving to Computer hardware & software as this discussion is about laptop batteries.

Cool stuff!
I have seen that, on Gumtree, people are advertising that they are wanting old dead, used or new laptop batteries. I wonder if those people are doing the same sort of thing as me, i.e. disassembling them, then testing the cells?
If there are any laptop batteries you, @S2M, @Zak or @Kyx could get, that they don't need, then that'd be great. If you wanted to take them apart and test them, you could do, or I could do it!

I keep all my old batteries in a jar then throw them away when the jar is full
I'll put them in another jar now, and when that jar is full I'll send them over

If your batteries run out of life, you should take them to a battery recycle point, rather than throwing them in the waste! Though of course, they probably have some life left, which I can make use of (thanks!).
Speaking of, have you watched this ye?

I did this for a good 2 years and I have a ton of batteries left over from that - if you want free batteries, you should try it. All you need is a multimeter and a battery source.

Awesome. I have got tons of batteries that way, including Ni-Cd, Ni-MH, Li-Ion and Li-Po. Virtually all of them have turned out to be good. In fact, I've got a good 200 Ni-MH batteries that need charging.
Plus, I have got even more alkaline and zinc batteries that way. I separate them into new (1.5V+), good (1.0-1.5V) and dead (<1.0V, or those that have leaked). Only the dead ones get recycled. The rest are salvaged and used in my appliances.
Going back to the laptop batteries, I have disassembled all of the laptop battery packs and they seem to all hold a decent voltage (>1.5V). Any Li-Ion cell below 1.0V should be discarded, as they may not charge up very well (if at all).
3 of the laptop batteries (from the HP pack) have been capacity tested and turned out to hold a good capacity (over 2000mAh per cell). The rest all need charging, and testing.
And when you've only got 2x chargers (a TP4056 module and a balance charger) and 1x tester (the aforementioned balance charger), it's gonna take a while... Discharging the cells at 1A each means that a cell with 2000mAh of capacity will take 2 hours to discharge!
