That info is awesome! Been dumpster diving for over 30 years and wish there was a site I could just type in a zip code and “Gold “ could be found.

Fellow dumpster divers,

  I recently came up with a lion Makita battery pack while diving in a Home Depot recycle bin.  While researching the Sony 18650v batteries inside I came upon some good reading on these "konion" Sony IMR cells and their rumored self balancing properties.  I don't understand it fully so I will just suggest any interested parties google search "konion self balancing" and read what the folks at endless-sphere.com have to say on the subject.

I’m jealous.

The Best Buy near me has elaborate recycling bins, with a rubber flap “valve” and a sloped baffle, and its right by the front door 6 feet from the loss-control guy. I need to find some places with more accessible bins. I haven’t seen any at Home Depot, and they aren’t listed on the county’s list of battery recycling locations.

A friend of mine, not a member here, but into flashlights none the less sent me these pics of a 40V Kobalt battery pack that HE found in the Lowes recycle bin. It was only half full with only 10 cells. The cell info is scribbled onto a piece of paper on the desk. The pack claims to be 2.0AH, that would mean those are 2000mAh cells. He claims there is also a 4AH version of this pack, so that one would be full with 20 cells.
This pack, like the one I found appears to be brand new

Walk in like you own the joint and help yourself. My Best Buy is set up identical to yours. The absolute worst thing that can happen is you will be asked to leave. Who cares what anyone thinks or cares, you are a battery junkie and have to get a fix…… NO Guts NO Glory NO Batteries!

I found the ultimate item in the recycle pile today… a small metal box that ENDLESSLY chants Hare Krishna mantras… 6 different ones, selectable by a button.

It has a line cord coming out that has round pins on it… probably 240V. Digging out my plug adapter I verified that it does not work on 117V. Opening it up revealed a power supply with center tapped transformer, two diodes, and a capacitor. Voltage out was 2.2V. I replaced the two diode/center tap connection with a full bridge connection. Yipee!

I think that box was in a Twilight Zone episode.

The only way to shut it off is to throw it away! Now YOU’RE stuck with it.

Do they just let you go thru the recycle bins or do you have to ask? Only real recycle bin for battery packs round here is best buy

 

Best Buys are great because they get all kinds of batteries and lots of them.  I wouldn't bother asking.  Likely to get a no.  Better to just do and beg forgiveness if confronted.  Most employees probably don't care one way of the other.  Just in case one is there that cares, I just go up the bin with a triple layer of plastic grocery bags and act like I'm putting batteries in the bin.

I’ve had many a good foray in the local recycle bin which included a motherlode of 7AA Eneloops and 3 AAAs. I’ve had Tronics, Energizers and Lloytrons and even a smattering of alkalines that were pretty much full. Some of these were no good with low capacity, high SD or not retaining a charge but for us “enthusiasts” this is just the fun of it all.

These days however, I’ve curtailed my forays as there can only be so many times that I can spend dropping off a couple of spent cells in the bins to try and hide my foraging. There’s something so damn tempting about getting something for nothing!

This time brand new still hermetically sealed!
WTF?


146Wh!!!!!
I know it claims 40v, but I now suspect it will be 10s2p for 42v charged and 36v nominal. Divide 146 by 36 and you get about 4. That means this pack will contain 20, 2A cells.



There they are. 20, Sanyo UR18650RX
2050mAh cells. They were sitting at 2.8v each and I am testing them now.
(It takes a long time to test 20 cells)

I recently found an unused spare laptop battery on the “Please take me” table at work. I now have 6 very good never previously used batteries for my lights!

Damn, dcho.  You brave (or maybe a bit crazy).  This thing looks like a short challenge with an attitude:

Hey Harvey, If you asked about Judisam we could use the initials HKJ for you. Smile

Just to be clear for the other folks:

The short version is Hare Krishnas are not buddhists (similure robes) but not similure systems.

The numbers are starting to come in…..
So far the first 8 I tested have capacities in the high 1900’s
I got this pack at a Lowes and I’m sure it was Lowes that threw it out, unopened.

There are other parts besides the cells that can be useful from these packs. Here is a pic of the BMS board from this pack. It just happens that is the mate to the header on the 18v Ridgid drill pack battery. I will remove that header and put it aside, someday that will be useful.

I showed my father how I use to get high drain cells before I started buying the latest. One of the 40v packs like in the OP was in there. Quit beat up on the outside, but 2 of the charge-level LED’s light up just like in the OP. My father didn’t have any security bits at home. So I didn’t get to tear it down for him in person. He seemed quite fascinated and excited about the concept. I picture a whole stack for packs waiting for me the next time I visit.

Get the 100 bit set from Harbor Freight and you can open almost anything which is screwed together. A few of those bits I’ve never seen for sale anywhere else and a few of those oddballs proved useful here. Worth the few bucks cost and good for gifting to the budding DIY’ers in the world Smile

Ima4, tell your Dad there are screws behind some of the labels. On mine I peeled one off and split another with a knife at the seam.

An update on the one I mentioned in the OP. Since them I bought the toolset it goes with and verified that it is a new fully functioning pack. The battery test button included in the pack has a loose connection and sometimes does not work, thereby giving the impression the pack is dead. Probably the reason it was chucked into the bin by HD. There is a silicone dab of goop over those connections so it is not easy to reflow. For the time being I have decided to leave well enough alone and leave it as is.
It is a perfectly functioning pack. Big Smile

Thank you SawMaster. I will check out that bit set. Sounds great.

Thanks for the heads up on the hidden screws dcho. My father has one of the Thor X type lights like you modded here that no longer works (dead battery). If the cells are good, thinking of making him a 4S5P pack with balance leads for charging. Then, convert the light to HID. Maybe also rig it so that he can use to also jump start a car. Would need to figure out how to LVP the pack though.

I have converted a couple of old 12v SLA battery halogen into HID with salvage packs. I go 4s4p and have run 35w to 55w balast with 35w bulbs. I deal with torx security screws with a automatic center punch on the pin.They usually break or smash pretty quick YMMV.I use H3 size bulbs and do the balance leads with the hobby charger.
