Hi All…

I’ve been busy dismantling laptop batteries and I’ve found some cells which I can’t identify.

They’re 18650 unprotected with a translucent red wrapper and are printed HCVFIH5 with 082532 printed underneath, slightly (1mm) raised positive pip with six vent holes and a white plastic ring loosely held on by the wrapper.

I’ve tried Google with no luck.

I’d just like to know out of academic interest if they’re a known brand or cheap knock offs. They came from a non-original Dell C6xx battery.

Cheers

PS SWMBO has suggested I put up a shelf for my collection!

Do they have anything stamped into the plastic (not printed) ?

If they are Sanyo UR18650EX, Ohaya has a thread: High risk Laptop Battery Pack deal?

No… nothing stamped into the plastic.

Thanks for the thread link,

Out of the Dell battery pack (possibly a replacement) that I took apart to get these cells, both read zero V so I recycled them at our local store - didn’t even dream of trying to charge them. The other 6 out of the pack read 3.75V or so. These seem to have have charged OK on my I4 V2, I just have to dig around in the shed to get my decent test gear out then check them properly.

The other pack I took apart was original Dell with 8 Panasonic cells, same thing 2 bad and 6 good.

Thanks… I tried really hard with a magnifier and couldn’t find anything. I could be my tired old eyes!

Try with a light in front of the battery, use the reflection… Like this

x= unknown.
i guess you will have to test them to see what is left of their capacity.
they are quite old.

Tested them, and all are around 1.800 mAh, witch is pretty good i think! :smiley:
