I've bought a replacement battery from ebay recently, told to be genuine, but I've read that the 2nd block of letters and numbers show the part no., and I couldn't find anything using mine. Could you confirm it please, if it's a Dell one?
KR-049VTIP-83620-28S-CISF-A01 is the serial of it.
Solved! Go to Solution.
If it was purchased from Dell, it's genuine. Otherwise, ask the seller. That product ID's date code indicates the battery was built 2012 -- so if it is original Dell, it's been sitting on a shelf for a while - or is used.
Do you have the old serial number from the previous battery that you can Private Message me? The serial number you posted looks like it is not a real Dell battery (at least at first glance).
thanks for the quick reply, I just can't decide if its good news or bad of course the seller says that its genuine and it was not used before (0% wear level), however the nominal capacity written on the outside shows 65Wh, while a diagnostic program found it to be 57,72Wh. But this would not bother me at all, if after the 2nd discharge-charge cycle the wear level indicator didn't show 9% - if it goes like this it'll reach EOL in 2 months... Could this be because of the long time spent on the shelf?
thanks for your quick reply, though I can't tell if it's good or bad news for me of course the seller claims its genuine and it was not used before (0% wear level). However the nominal capacity written on the outside is 65wh while a diagnostic program read 57,72Wh, and after the 2nd discharge-charge cycle the wear level indicator jumped to 9% (if it goes like this it'll reach EOL in 2 months...)
Could this be because of the long time on the shelf?
Yes, it could well be the age of the battery. Lithium ion batteries age, used or not -- and a 5- year old battery has 5- year old cells in it and may not deliver its design capacity.
I know I sent you a PM to re-verify the Serial number since it looks like it has an extra character and different part # vs the original, but also, ejn63 is right with his assessment on the age (assuming it wasn't a random serial they used from a 3rd party). Just to add, for example if I remove one of the characters that looks wrong to me it is showing as 5 years etc. in an internal tool as well.
I can confirm the serial no. (double checked reading the matrix code). It is interesting, that reading the code of the old battery gives all the characters in 1 block, but the new one gives it exactly as I wrote, in multiple blocks separated with hyphens. So the extra digit seems to be in the 2nd block...
If the battery is in fact this old, what can I expect in the near future?
Thanks again to both of you.
If it is this old, it might not last as long (as mentioned by ejn63). The other thing that is interesting to me on the digits that were used is that the battery is missing the model number in the serial (meaning the battery, while not a Dell battery might not be as old since it is using different serial convention). For example on the Serial you gave me in PM on the original battery the serial number contains 5G67C, which is the model number for that one. The one you’re asking about does not have a part number/model to me, when they sold you the battery did the claim what model it was?
