Reddit mentions of Lenovo 6 Cell 72Wh Battery 61++ ( 4X50M08812, Retail Packaged) For P51S ,P52S, T470, T480, T570, T580, TP25

Found this sub while looking for a new laptop to replace my surface pro 3. I'm a Psychiatry Fellow and spend most of my day typing notes while people speak, so a T series keyboard sounded like a good priority. I also do photography and graphic design on the side, utilizing several Adobe CC products, so 8th Gen processor, upgradeable drive/ram, and color accurate screen were essential. Almost went with X1C6, but ultimately, longevity and value (still just a fellow) were more important than portability and brightness. So in the end, the T480 seemed like the best fit (though I really miss having a touch screen).

Below is my custom config ordered during the Black Friday in July sale, followed by my mods:

Ordered specs:

• 14.0" WQHD (2560 x 1440) 300 nits, IPS anti-glare (non-touch)
  
  
• Intel Core i5-8350U Processor (vPro)
  
  
• 4 GB DDR4 2400MHz ram
  
  
• NVIDIA GeForce MX150 2GB GDDR5
  
  
• IR & 720p HD Camera with microphone (mandatory with WQHD screen)
  
  
• Backlit Keyboard - US English (accidentally ordered without, but realized it and adjusted thanks to you guys!)
  
  
• Fingerprint Reader
  
  
• 128 GB 2.5" SATA3 Solid State Drive
  
  
• Smart Card Reader (for literally zero reason, my only regret)
  
  
• 3 cell Li-Ion 24Wh external battery
  
  
• Intel Dual Band 8265 Wireless AC (2 x 2) & Bluetooth 4.1 with vPro
  
  
• Fibocom L850-GL 4G LTE-A cat 9 WWAN
  
  .
  
  Upgrades on arrival:
  
  
• RAM: HyperX Kingston Technology Impact 32GB Kit (2x16GB) 2400MHz CL14 DDR4 SODIMM HX424S14IBK2/32 Link
  
  
• SSD: addlink S70 2TB NVMe PCIe Gen3x4 M.2 2280 SSD R/W 3500/3000MB/s Link
  
  
• Lenovo internal m.2 Drive Enclosure (ordered as add-on through Lenovo; necessary to install m.2 SSD)
  
  
• Copper NVMe heatsink with thermal pads Link (ultimately, unnecessary because enclosure came with an attached thermal pad, but doubled up anyway and yes it was a tight fit)
  
  
• Extra battery: 6 Cell 72Wh Battery 61++ Link
  
  
• Wi-Fi/Bluetooth 5.0 card: Intel Wireless-AC 9260, 2230, 2x2 AC+BT, Gigabit, vPro Link
  
  
• Wallpaper
  
  The screen is beautiful, and I'm digging the anti-glare matte, though my SP3 glossy screen made colors pop more. I installed the calibrated color profile from the notebookcheck.com review of the T480s with what I assume was the same WQHD screen. Here are the instructions I used from notebookcheck.
  
  Replacing the internal components was a breeze, though unfortunately, I watched the Lenovo disassembly video that showed front clips being disengaged with spudger, so now I have a front gap. Also broke a battery compartment clip but whatever.
  
  I installed windows fresh using a recovery flash drive made before swapping in the NVMe drive. I'm fully updated through both vantage and windows update, which took a few hours.
  
  Ultimately, I'm ridiculously happy with this build. The keyboard is a DREAM except for the annoying fn button placement (who thought this was a good idea?). I threw in a Logitech MX Master 2S for desk work, but honestly, this trackpoint is a game changer when I'm working on my lap.
  
  Any other mod suggestions??? Questions??? Comments???

Hi

I recommend not buying the 72Wh on Amazon. That particular model has not worked with the T480 for me. However, buying the 72Wh from Lenovo's spare parts website works fine and is only $80. link

Unfortunately, it seems these batteries are out of stock. I'm not sure where to get a working 72Wh battery.

The working battery that I have is a 61++ made by LG Chem from Lenovo's replacement parts site. The non-working battery is a 61++ made by Sanyo Electric Co., Ltd. from Amazon (link). Both are real, genuine Lenovo batteries. They use a few different companies for batteries. I haven't been able to find out why the second battery won't work. It's detected as a battery in Windows and Linux, but all values (capacity, charge state, etc.) are unable to be read and the battery won't do anything. I've tried to find out how to debug ACPI, but I haven't found much.

I even got a replacement for the non-working battery, but it was the same manufacturer and still didn't work. I took apart the first one and all the cells were good, all the circuitry looked good as well.

Just a heads up, your link is broken.

I just ordered my T480 + extra battery and I can’t wait. Just ordered my extra six cell used from a seller off Amazon. Order details: Lenovo 6 Cell 72Wh Battery 61++ (4X50M08812, Retail Packaged) For P51s, T470, T570 https://www.amazon.com/dp/B06WGMPFCD/ref=cm_sw_r_cp_api_i_MV9-Ab12WAKX0)
