## Description

eoSync CMOS Battery BIOS CR2032 with 3V Plug for PC/Laptop : desertcart.co.uk: Computers & Accessories

Review: Brought my notebook PC back to life - As has been mentioned elsewhere this is basically a battery on a wire. In addition, desertcart managed to lose the parcel for a day - and then I had to charge the battery overnight before it worked. So why 5 stars? There are various ways the product could be wrong - the wire could have been too short, the shrink wrap could have been too thick - but it was perfect. Not without effort on my part, but this tiny cheap battery has brought my £1500 gaming notebook computer back from an early grave. It was dead - thanks to this battery it lives again! Extreme value - even if I did have to leave the notebook plugged in overnight to charge the CMOS/BIOS battery!
Review: It’s a battery - It works. I put it in my laptop and now that works too. Good stuff.

- EASY TO PLUG, EASY TO USE: Equipped with a 2 pin plug, it is so easy to connect to a motherboard or a laptop. It could also be used on a server, wireless Bluetooth products, machine core, electronic key, an IC card.
