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

Arrived OK. Works OK.

Bought to replace an original T-420 battery, works great. In fact, after two full charge/discharge cycles upower is reporting 96Wh, over a designed 84Wh. Some other reviewer found something similar, so to anyone looking at these, it seems like the manufacturer did the honorable thing and rated the battery ~15% lower than its actual performance. Rare and nice to see.

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

Physical build quality is very good, and fits exactly like Lenovo original battery. In Lenovo Power Manager app, my old OEM battery said the design capacity was 86 Wh but my full charge capacity was only 31 Wh. When I initially installed this new battery, it showed the design capacity is 86 Wh but the full charge capacity at 84 Wh. I performed a battery reset with Power Manager (something you should always do with a new battery). Now the cycle count is 2 and the full charge capacity shows 100 Wh (and the design capacity still shows 86 Wh). This is a nice increase in actual capacity over design capacity but I will come back in 6 months with an update on how the full charge capacity holds up. I estimate my OEM battery charge capacity declined about 10%/year so hopefully this one is similar. If it is, you can't beat the value of this replacement.

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.
