0A36303 0A36302 Laptop Battery Compatible with Lenovo ThinkPad T430 T530 W530 T420 T410 T520 T510 W510 W520 L412, 42T4751 42T4793 42T4755 42T4763 42T4848 45N1000 42T4791 51J0499 42T4235 (97Wh 9-Cell)

I think it was only $29 half of what others cost, and it fit perfectly, charges and holds charge like new!

I bought this Battery for my T420 at a bit of a premium ($45) for a generic replacement. Most of yer sub $20 generic batteries are 6600mAh capacity. This one promised equivalent to an OEM spec 94Wh capacity. It's labeled as such. The casing looks exactly like an OEM with the branding and serial numbers removed. Snug fit. Good manufactring tolerances. My other generic is wiggly AF.My first order of business after receiving it in the mail is to start charging it to capacity and check the power statistics panel in Ubuntu Mate and tlp-stat for detailed battery information. Okay the manufacture date is June 2019, but the first use date is probably an autofill date since it says 2013... no big deal... SANYO cells... that's fine, showing 2 cycles, okay... Design capacity and last full charge are a match... THERE IT IS... 86.6 Wh design capacity. Still alot better than a typical >20 buck generic, but not the 94 Wh capacity on the label and in the listing.EDIT - Okay, it's only a few days later and this is wierd. I managed to full charge, deplete, and full charge it again, though I didn't do it in a single go. I got most of the way depleted ~20% first night, but I had to do something important, so I let it charge on the dock overnight and then depleted and charged it the next day. It took about 4-5 hours to deplete from full on my lappy with normal use. (T420 i7-2640M Ubu Mate 19.10 w/tlp) It charged up to full in about 3 hours. Then I ran tlp-stat -b again... This damn thing is actually showing last full charge capacity at 92.3Wh. Capacity is 106.6% of design? Is this thing cursed? The cycle counter is up to 5 cycles, and it's showing over design capacity, and pretty close to that 94Wh? What is with the chips on this thing? Is it overcharging the cells??? Are these measurements real or bunk? I don't frickin' know.We'll have to see how it holds up over time. My OEM that I bought immediately after getting the laptop lasted almost two years of full cycling 4 to 5 days a week and was still managing a little less than half capacity. Only about two hours of regular use. When my cheap generic backup battery is lasting longer than the OEM, it's time to replace. If this thing can hold up similarly, I'll have no complaints.

Arrived OK. Works OK.

Laptop functioned fine with original battery for 8 years (around 3000 days).3 days after installing new battery; Motherboard is DEAD.I have never seen this happen before, but I doubt it is a coincidence.TCORE 0A36303 0A36302

I purchased a battery for my laptop from Tcore 2022 on May 1st, which doesn't hold a charge. According to their warranty, they will replace the battery if I contact them within 365 days. I couldn't find the contact information and I left a customer review on April 4th just in case they may answer my inquiry so far they haven't. My warranty will be up in two weeks so I appreciated it if you reach out to them or let me know how how to reach out to resolve this issue. I purchased a battery from you last year on May 1st, and it doesn't hold a charge. I can't find where I reach out to you for a replacement so I am trying here. Please advise the next steps for the replacement . Thank you

Seems to hold a charge well and lasts many hours before needing to be recharged.

Good quality product. I'll give it 4.5 Stars"
