LeFix 2 Pins 2 Wires BIOS CMOS Battery for DELL(D830 E6530 N4050 E7270 .) HP(CQ41 8440p G4.) ASUS(S56 X611.) Samsung(R467 R458) Backup Reserve Button Cell Batteries (Regular Polarity)

This battery was used for a SnapOn Diagnostic Scan Tool. The unit is a Windows-based scanner for automobiles with OBD-II engine controls from 1996-on. The tool needs this battery internally on the computer board so it keeps the CMOS date current along with other needed items. Without the new battery, the scanner would show the wrong date in the memory and the scanner software wouldn't load for use. In my unit, changing the battery required opening the case, but since my unit is out of warranty, it wasn't an issue. After gently opening the body and carefully detaching the old battery from the computer board, I installed this new battery with its sticky pad to the board and closed it. Upon turning on the scanner, I reset the date and time in the Windows control panel and restarted the scanner a 2nd time. When the scanner was restarted and the WindowsXP system booted, the corrected and maintained date loaded in the CMOS. Now the software can be used again and the scanner works well! This battery is a special, required item that has a special wire harness that locks onto the circuit board specifically for the function it serves. It is a CR2032 with tabs and wires attached because the board doesn't have a slot like other items have for the 2032 battery. The buyer only has to specify how the wires are arranged in the terminal because the pos and neg wires have specific spots in the other part on the board, just like any other battery. I was so glad to find this special battery on Amazon. It saved my used $1800 scanner from being a paperweight!

Worked fine on an ASUS Z390-1 ROG STRIX GAMING motherboard in an Origin computer.

My CMOS battery died, so I got this one. It's good, it works. No more error

Just writing a review so that people are aware this is not compatible with Dell Optiplex 7090 Ultra. It's the correct battery, but the little white plug is just barely the wrong size. It looks correct, but it isn't. This is not the vendor's fault, the item description does not state that the battery is compatible with this particular model of PC. But I can't find one that specifically states it's compatible, and so I'm randomly/blindly trying different brands of these cmos batteries.

The connector on the battery was not correct. I had to cut and resolder the old connector onto the pigtail. The battery was fine and worked on the computer once I changed the connector.

easy peasy cmos replacement battery for a dell laptop. direct replacement. good price point if it lasts as long as the original that's a decade of use. Recommend.

I purchased this LeFix CMOS battery to replace the dead one in my older Dell laptop, and it worked flawlessly. Installation was simple and straightforward, and my system's BIOS settings held immediately after reboot — a clear sign that the new battery was doing its job. What really impressed me was that I was able to use the same battery to revive a mini PC that had also lost its BIOS settings due to a failed CMOS. Both devices recognized the battery right away, and I haven't had any issues since. In my case, storing the equipment in cold conditions seemed to drain the original batteries faster than expected, so having a reliable replacement like this on hand is a must. Shipping was fast, packaging was secure, and overall, it saved me a lot of troubleshooting. If you have an older Dell, HP, ASUS, or Samsung system that’s acting up during boot or losing BIOS time/date — this battery is a simple and inexpensive fix. Highly recommended.

Works as intended. Glad I found it.

Ich habe lange gesucht und die richtige Batterie mit den richtigem Anschluss für den Intel nuc10fnh gefunden. Eingebaut und jetzt funktioniert der Rechner wieder problemlos 🙏👍

Got it as a replacement for a Dell latitude 5430. Fairly easy to swap. Same connector. Worked first try. Easy and cheap

Van bien

J'aurai aimé que le câble soit un peu plus long, mais pas d'information de ce côté

Spedizione un po lenta (11 giorni), tuttavia la batteria mi sembra di buona qualità, è arrivata pienamente carica. Nel mio notebook la polarità era invertita, è un fix che potete fare da voi switchando i due pin interni spingendoli fuori con una pinzetta appuntita e reinfilandoli nella polarità che serve a voi (cercate su yt). Consigliata.
