Let The Testing Begin

[BigGun]

I recently purchased (24) CALB 180 cells NOS. I've learned after building numerous packs of all types to Test everything. The more aspects you test the better the pack will perform. I'm just getting started and thought I had built enough cables to keep my assembly line going. Almost, had to use this big ones on the the bigger charger. ( who was the one that decided Binding Post were a good idea for a high output charger, too much sag )

This is #1 , Gonna be a long process @ 25amp discharge.

Looks like these cells will test well. Parameters 3.6v - 2.7v ( Hoping there's no duds )

Cell # 1 ICHARGER X12 /189.6 AH --- SHUNT / 181 AH

Cell # 2 ICHARGER X12 / 188.1 AH --- SHUNT / 180 AH

Cell # 3 ICHARGER X12 / 189.7 AH --- SHUNT / 182 AH

Cell # 4 ICHARGER X12 / 190.2 AH --- SHUNT / 179 AH ( this is why I use two measuring devices/ I hate contradictions )

24 cells...

Multi-hour testing...

You're gonna be at this a while.

I recently purchased (24) CALB 180 cells NOS.

I would like to ask for some more information on the Cells and testing if possible. I would like to take the data you have and expand the testing that has been on Calendar life testing. Ive done a lot of this style of testing on CAM72 cells and a little bit on the CA180s you have here. What I would need would be the Test results of the cells as well as if they have them the original cell codes. These would be a white or yellow barcode on the side of the cells. These allow you to know when the cell was manufactured. Manufacture date on mine is 10/27/13 for example.

The bar code looks like this on my CA180

It's a shuffling match between ready to be tested, discharge and recharge back to storage

All these cells have the same Date Code. All of these are from the same batch 3/11/21 Almost consecutive numbers also.

I have some of them old ones like you have I'm replacing. They're just getting to that 80% margin. I look back and shake my head how much I paid for these used cells 4-5 yrs ago. Not like it is today for sure.

I figured I'd go this route because of the mounting bolts are solid and take a good bit of torque. I wish they still made cells like this. I have some Winston cells that have even beefier terminals.

I'll be old and grey by the time this is finished ( wait I already am ) I'm use to doing 24/ 18650s at a time, I built a holder to parallel charge 24 at a time then discharge in some what calibrated Opus chargers.

My big thing is I don't leave this stuff going while I sleep.
