Does not fit Lenovo 4th Gen Thinkpad X1 Yoga TP00110A
Does not fit Lenovo 4th Gen Thinkpad X1 Yoga TP00110A even though Amazon's search helpfully told me it did. It has the wrong plug, so I was gonna resolder the leads, but t it also too thick to fit into the place it belongs under the main battery.

Works for Dell xps13 9350
Works for Dell xps13 9350. The cable is much longer than original. I received the battery fully charged with 3.11V. Just for your info XPS13 will not charge main battery if you have dead ML1220. If you have dead main battery check the ML1220 voltage first.

A Lifesaving Spark in the Eternal Night
Greetings, fellow nocturnal beings and creatures of the night. I am Lord Scootimir, sovereign of the shadowed realms of Transylvania. Amidst the ancient corridors of my castle, where time seems to stand still, I discovered a modern marvel - the LJCELL CMOS Battery for Dell Alienware Alpha R1 Steam Machine i5 i7 Desktop. In the eternal embrace of darkness, where the moon's glow is my daylight, technology is a rare but cherished companion. My Alienware Alpha R1, an artifact of otherworldly intelligence, had succumbed to the mortal ailment of a failing CMOS battery. The LJCELL CMOS Battery came to its rescue, like a potion of revival. This battery, a mere trifle in size, holds power that belies its appearance. Installing it was as effortless as turning into a bat - a simple and swift transformation. It fit perfectly into my machine, as if forged by the dark alchemists themselves. Once installed, it was as though a curse had been lifted. My Steam Machine awoke from its slumber with renewed vigor and precision. The settings, once lost in the abyss of forgetfulness, held steadfast. It was as if the machine had been imbued with immortal life, much like myself. The reliability of this battery is akin to the eternal night - constant and unyielding. It sustains my machine, allowing me to delve into the virtual worlds and escapades that offer respite from my timeless existence. In summary, the LJCELL CMOS Battery is a beacon of hope in the technological darkness. For those who dwell in the shadows and require a steadfast source of power for their devices, this battery is a treasure worth possessing. It breathes life into machines as the night breathes life into me. A full five stars, bestowed by the Vampire Lord of Transylvania.

Worked on Dell 7400 2 in 1 laptop
The wire is lil longer then the space available. But routing it around the battery took care of it. I was not able to save the date/time in bios. Sign of dead bios battery. This one worked perfectly and now my laptop works fine. Thanks to the seller for one day shipping.

Fail.
I followed instructions to make sure i was ordering the right one. Triple checked. Somehow, however, it linked me to this one and i dont even own a dell. Cant get my laptop to work i hope i didnt fry it. Its only 8 dollars for another one, but when youre homeless and have no income, ordering things that dont work how they should is detrimental. So now this battery is what im stuck with for my lenovo t430. Thanks.

Works but make sure to install correctly
Revived my Alienware Alpha that was sitting in storage. Took three times to get it to actually work. I just needed to hold the power button to drain all the electricity before plugging in plug and also installing battery.

Does not work for PlayStation 2
Pinned backwards and and the wrong connector for my PlayStation 2 so despite what it says; this was a waste of money.

Great CMOS battery, cheap and fast delivery
My laptop suffered one of the many symptoms of the CMOS battery dying and so I needed a CMOS battery replacement quick. Found this one to be what I needed. Quality seems good, they're all the same, either good quality or poor. Price was great, there are more cheaper options and there are more expensive replacements, I tend to go middle ground. Installation was simple, look for a YouTube video and you can do this easily on your own. My laptop is a small 2-in-1 so the battery wires were just a tad long, The battery cell fit in place just right just the wires just a tad too long but there was enough room to loop the wires around without any issues. Better to have too much wire length than not enough. Replacement battery works exactly as it should, as old as this laptop is it honestly will probably now last longer than the rest of the laptop.
