45N1112 45N1113 Laptop Battery Replacement for Lenovo ThinkPad T440 T450 T450S T460 X240 X240S X250 X260 A275 Series 45N1111 01AV459 45N1109 45N1773 45N1108 L16M3P71 45N1110 11.4V 24Wh

I ordered this internal laptop battery at the same time I ordered a new external battery (from a different company). And I'm glad I did because my external one expanded and had to be thrown out and this internal one let me keep using my laptop on the go. I've had no issues with it, and after 6 months of use, this battery has done me perfectly fine.

There was a problem with the first battery I got - after 6 months lenovo vantage was saying that the battery has reported a fault and charging has been disabled. Contacted the seller and they were quick to respond and sent a replacement free of charge with great communication all along the way. Highly recommended.

This battery installed and works perfectly. I was concerned that, since this is branded as a non-OEM battery and I paid less than $50, there might be an issue with the built in battery check on my X250. I have purchased "OEM" batteries in the past that have failed this built in test (and would not work in my laptop); but I had no issue with this battery. The battery life has surprised me so far. I bought my ThinkPad second hand, and the original internal battery only lasted between 20-30 minutes. Plenty of time to swap the rear battery, but not much else. I have removed my rear battery and been using the internal battery for basic web browsing over the the past 1.5 hours, and it still shows 63%. It could be bad calibration at this point, since I have not fully cycled the battery; but even if it died while I typed out this review, I would be happy with 1.5+ hours from the internal battery. One tip: peel the JIAZIJIA brand's sticker off before completing the install. There was a nice little surprise under there on the battery I ordered, and so far, the performance confirms it.

Great price for a replacement battery and it fit perfect when it was installed. Unfortunately my laptop wouldn’t power on once it was installed and charged unless it was plugged in. I am outside of my return window so stuck with a paper weight.

After four years with my T450s, the internal battery of the laptop would only charge to 50% capacity. Because of this, I continuously found myself in situations where the laptop would power off due to low charge. Either that, or I would have to stay connected to a power outlet as long as I was using the laptop. I decided that I would replace both the internal and external batteries of the laptop. I believe Lenovo no longer sells genuine internal batteries so I bought this item as a replacement. Unfortunately I ran into a couple of hiccups with this battery. First the connector at the end of the cable that plugs into the battery port was slightly cracked. It didn't seem cracked enough for me to worry, however it is something that I will keep on the back of my mind if this battery ever ceases to operate. Second, the battery capacity is not 100%. The battery arrived with no charge, and after one full charge tlp shows the capacity to be 97.9%. This is not horrendous but it does make me consider how long this battery will actually last. All in all this battery seems to be a worthwhile replacement. I'm getting around 2 to 3 hours of web browsing use at 30% brightness just from the internal battery (discharging from 80% to 30%). This battery coupled with the 6-cell external battery has renewed the life of my T450s and I'm now able to use the laptop unplugged without any concern. Just in case it helps, here is the output from sudo tlp stat: +++ ThinkPad Battery Status: BAT0 (Main / Internal) /sys/class/power_supply/BAT0/manufacturer = SANYO /sys/class/power_supply/BAT0/model_name = 45N1773 /sys/class/power_supply/BAT0/cycle_count = (not supported) /sys/class/power_supply/BAT0/energy_full_design = 23200 [mWh] /sys/class/power_supply/BAT0/energy_full = 22710 [mWh] /sys/class/power_supply/BAT0/energy_now = 7270 [mWh] /sys/class/power_supply/BAT0/power_now = 27061 [mW] /sys/class/power_supply/BAT0/status = Charging tpacpi-bat.BAT0.startThreshold = 76 [%] tpacpi-bat.BAT0.stopThreshold = 80 [%] tpacpi-bat.BAT0.forceDischarge = 0 Charge = 32.0 [%] Capacity = 97.9 [%]
