This is a replacement of the internal battery for my Lenovo T480 Laptop. Exactly what I ordered and delivered early.

This battery is unusable as it's not recognized by the system.

Perfect fit and operation.

UPDATE: Seller contacted me via messaging and resolved warranty claim. I would still suggest that they provide the email contact information they refer to in their warranty information, so others can submit claims.ORIGINAL POST:The manufacturer's/seller's warranty states to "contact us by email any time..."; however, there is no email provided.I reviewed the product data/manual provided and the same warranty statement is made, with NO EMAIL provided.I searched Google for the Anepoch website to try to get their contact info, but could not find anything.I need to contact Anepoch for a warranty claim, but am unable to do so.If someone can provide me with this information, and my claim is resolved, I'll be glad to update this negative review!

I bought two of those for Lenovo T480s.First one worked on the first try.Second one just didn't work. Laptop wouldn't 'see' the battery. I had to disconnect, reconnect, disconnect, reconnect the battery at least 5-6.I don't have much trust in it.... Will monitor for a few days. Might end up sending it back... Disappointing.

Stopped holding a charge after 8 months. Correct charger voltage and wattage used. I am now out of my return window. When charger is removed, laptop dies.

Revived my laptop

Seem to work well, hold a charge. The instructions and tools were helpful too. Haven't used it long term yet, so don't know how it will hold up.
