I do lots of work on laptops. These batteries have a long enough lead to be nearly universal. I've used 4 of them already! Much cheaper to buy them this way than one at a time on listings saying they 'fit' your computer. Well, these fit most computers, so buying one that MAY fit and paying 5 times what you'd pay to get these that PROBABLY fit... well it's a no-brainer.

When purchasing these CMOS batteries, verify twice that you are purchasing the correct option for your computer model - not just the brand of your computer. There are different connectors for these batteries. Compare the old connector to the pictures as a double check to make sure of the correct battery. Once you have the correct battery and connector, for those with computer maintenance experience, it is a straight-forward replacement. As for battery life, only time will tell.

Just what I needed, although I wish I didn't have to buy 10. Of all the computers I've ever owned, this is the only one with a pigtail connection for the battery.

The pack I got had all the connectors wired backwards (plus is where negative should be): compared with the OEM KTS battery - terminals on the connector are reversed. While it's fixable with a pin and tweezers, it's annoying.The seller let me know that they sell both this and the reverse style of terminal, so maybe it was a mixup or something, but in case you are not sure may as well get both.

I had a 3 year old laptop that wouldn't boot. When I pushed the power button, it would flash momentarily, but then it would go dark. It's unfortunate that there wouldn't be some sort of warning or message when such a catastrophic problem occurs to indicate what the problem is. But there wasn't... as far as I could tell.In any event, I knew (hoped) that it was the $1 3v button battery. That it had died and the laptop was pretty much DEAD without it.Installing was super easy. There were a couple of screws holding the bottom of the laptop on. I removed them, and the batter was exposed... and easy to remove. the new battery fit perfectly. I put it all back together, pressed the power button... and bingo, the laptop came back to life.

I ordered quite a few. Not all are 3.2 volts. Out of 60, 10 had less than 3 volts. So i returned those. Still theyre way cheaper than all other brands. Plus i had the same experience with 5 euro a piece versions from a brand. A certain percentage had a few batteries less than 3 volts too. Somehow there is always a percentage off. For the money this is the best deal. Polarity reversed indeed.

Die Ausführung der CR2032 mit Kabel / Molex-Stecker offenbart eine gute Qualität. WICHTIG für den Anwender ist, dass vor dem Einbau die Polarität am Molex-Stecker geprüft werden sollte. In meinem Fall war + / - gegenüber dem Original vertauscht. Möglicherweise gibt es zwei Ausführungen.
