I too have just started out searching for cells. I found the first 100 cells pretty easy just from ald tool batteries and asking in a battery shop.

This week i stepped up my search and started canvasing battery and computer shops. I was about to give up asking myself, Is this really what i want to do?? I was also considering paying for recovered some cells on Ebay.

Today i decided to ask in a computer shop that i was driving past and the guy went out the back and came back with box after box of old laptop batteries. 92 in total. I offered him some money but he wouldn't take it.

So just keep asking and looking, you will find some.

I too was hitting brick walls asking people I knew in the IT industry, getting only a handful of cells in a couple of months. One day I asked a manager I know in a tool shop, and he said yeah you can have whatever we get. That was my first decent score - a box I could barely carry. So tool shops it was. I still get some nos but I've got a steady flow from about 3 shops, with other possibilities in the future.

Tool batteries tend to be higher current capability. Older packs range 1~2AH and modern ones are pretty decent capacity 2.5~3AH. I get far less zero volt cells from the newer packs, which stands to reason, as the old ones have lasted an age, and therefore more chance of total depletion.

I'll be using the 1~2AH cells in smaller and test projects - the first being a UPS I modified with an Anderson plug on the back, and I'll keep the 2.5AH+ cells for the endgame powerwall. Tool batteries are more work to liberate the cells, but with higher capacity and better yield of good condition cells, I think it will be well worth it.

Also, I get the odd high drain pack with 20700 cells capping at around 4AH. These have hit the market hard in the last year or 2 but we won't start to see them in high numbers for some time, if at all, due to their discharge rate capability. This means less stress, less heat and therefore less failures... so when we do get them, they'll be depleted or End-Of-Life, not failed.

IT places are good yes. If you happen to know anyone in the big firms around town, even better. I’ve ended up with more laptop batteries and tool packs than I can handle anyway.

I’ve given most of the laptop cells away now to my local hacker space peoples. Most laptops are now pouch cells so I’m afraid going forward you’ll be out of luck there.

Try big hardware places? Bunnings? Every place that sells packs must accept them back for recycling Smile law or something?

Something that is really cool to grab from your IT guys tho, dell laptop boxes! They are 100% perfect batter storage and sorting boxes. They are double wall thick cardboard, latching lid, handle (don’t rely on those!!) and hold from 300-400 cells per box.

They even have a lithium warning logo on them. The UN38.4 one Wink

Wondering what sort of tool shops did ask around because around my area places like bunnings are not that willing which gets annoying to sources these.
