Unknown Cells - Need Identification
#1
This thread is for the list of cells which cannot be identified. Most likely they are rewrapped but considering they're out there, I'm still curious in finding out the specifications. At minimum, if we can determine a brand and model number, we can get the pictures added to the database. If you recognize any of these cells and/or know where we can find information for them online, please let us know!

 
Solar Setup: 9x 320w panels, PCM60X charge controller
Battery Setup: 14x 120 cell 18650 packs, 48v configuration

Recommended Items:
Opus BT-C3100, Cell Heat Shrink, 4-Cell Holders

Definitely, has SANYO imprinted into the sleeve with no other visible markings.
Taking wrapper off it has an A above the Z and the spacing below closely resembles layout on cell

Are those purple ones 18650 or are they slightly smaller? I think I have a pile of those, I'll have to check.

According to a fellow who goes by Overmind of Borg, The blue ones are made by Chang Jiang BATTERY Co. Ltd. and are rated at 2200mAh new.
Considering mine all test above 2200mAh, I'd say I either got them relatively new, or they've held up very well. Certainly better than anything with "Fire" in the name, LOL.

I picked up 6 of these today from what appears to be an aftermarket Compaq battery.



A quick google search of HZNBE came up empty.

Please place this post where it is appropriate.

I pulled apart a power bank advertised as Lithium Polymer battery .It has 5 of these in parallel and the voltage not fully charged was 3.82 Volts . Advertised as 100,000 mah so each battery must be 20,000mah but there are no readable markings on any of the batteries

Awesome info.  Thanks  Just ran across 6 of them..  Was thinking it odd when I charged them with the Imax they charged up to 4.3v...  Wonder if I should still use them in the powerwall.  Guess they should be fine.
