Damaged modules. Is it safe to use them?

This is not possible, and unnecessary. I bought it from a guy who was selling his battery for about 200$ (500$, got it down). I didn't expect that I will get 34 good modules in the first place. I will check the capacity and if there are indeed a garbage, so let it be. Not a big deal. I mean the shipping would cost more than all of this modules.

 

Alright, I was finally able to put this modules for charging/discharging cycles and wanted to ask if this is normal numbers or not. Just to mention, this battery was staying for 5-6 month and the voltage was really low when I got it. i had 1 or 2 with 3 volts, some with 4v, and majority of them was at 5v. Also 5 or 6 modules still had around 7.5v.

Here is a link for google sheets with all charging/discharging cycles.

It looks like most of them did recovered to 4000-5000+ mah, but my concern is that the first discharge cycle was at few hundreds. Interestingly modules that had a normal voltage of 7.5v, for the first discharge they had 2000-2500 mah (like any normal modules). Also, just to mention module# 30 or 31 is leaking an electrolyte, not sure which one because I would need to inspect it first and then I wanted to try and measure the weight. Since 1035-1038g (more or less, depends on the module) is a usual weight of a module, I suppose the one that had an electrolyte leak, should weight way less that the others.

What do you think guys?

 

You didn't, I only mentioned that I got a good deal and nothing else. Based on the discharge numbers, (4500-5200 on average) they do look pretty good.

 

@TMR-JWAP sorry to mention you here, but I would like someone with enough experience to take a look and tell if it's okay to use them or not. Thanks!

 

You have cleared my concerns, thank you! Module #33 didn't get enough of cycles, I will run another one or two cycle and see how it goes. The average weight of the module for this year (2012) is 1013-1015 which is lighter than I've seen on gen2 prius. There is 2 modules that was lighter than the others (1006-1007), I did a load test on them and one of them dropped from 8v down to 6v really quickly.
