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.

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.

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.

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.

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.

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.
