ML1220 Rechargeable CMOS RTC Battery with Leads Cable Plug 2 Pins 2 Wires 1.25mm Pitch (CMOS, Laptop, Notebook, Motherboard, Bristlebots) Check Connector Specification Very Carefully

This is the battery I needed when mine died. What else can I say? That said, I wanted to make a point, because it's not been the first time excessive packaging was used when a small bubble-wrap envelope would have been the RIGHT choice. In this picture you see a small battery on a static bag on a paper envelope. Which was in this over-sized box. Imagine my surprise when I received notification that the package wasn't delivered because it wouldn't fit in my mailbox. It's a small battery. Really folks? Can't we perhaps fix that broken packaging algorithm? Maybe enough attention to this problem and they'll fix it. Please people, pay attention and give a care.

I ordered CMOS battery, and I have given the Model # also, the battery socket that goes on the motherboard is not right size. I did sort try to take out the battery from the side that is wires soldered to the battery. I am not going to return the battery, please see the attached pics to see the difference. I have attached the pics the two wires the one with smaller socket is the original sony battery with the model number ML 1220-M3(HLF)-F 0424.12 for Sony Vaio laptop model SVS151A11L.

I have a Dell Latitude tablet (Similar to a Microsoft Surface). I was having issues rebooting because the BIOS battery was dead and not charging. I could not find the exact battery connector for my model, but this battery was the right version and size. I had to cut the connect off the end and splice in my connector. The tablet now boots up without BIOS errors. If you have a device that this battery fits, you should have experience taking apart tablets and cell phones before you attempt the replacement.

Purchase on Feb 12,2022. Computer error alert said CMOS battery replace. Took it out and digital meter said only 2.0 volt

The bios settings and time are now being saved again. Direct fit for my IdeaPad S10 Netbook

Update: Mine won't hold a charge for more than about 3 weeks. Wasted my 9 bucks. On mine there is absolutely no label so I have no idea if I even received what I ordered: an ML-1220. Neither do I have any idea how old the battery is.

This battery fixed the problem. Replacing battery in an Azulle BYTE3 is a bit of a challenge. Wires were not long enough. I had to cut off old battery leads and solder the leads onto the new battery. Not a big deal, but an inconvenience. I assume new battery should last for years.
