    I have a server with M/B : X10DRC-LN4+
    Recently I've observed the following error :

    vbat_error.png

    According to Supermicro FAQ FAQ Entry | Online Support | Support - Super Micro Computer, Inc. the battery must be replaced. The battery type is : CR2032

    The question is : Which battery brand to choose ? Which battery is of a better quality ?

    REMARK : This server is relatively new, only 4 years in service. I have other servers which work for more than 8 years and I've never observed CMOS battery related issues.

    That is odd. Except for a manufacturing fault like an internal short, I'm not sure what would drain it so quickly.

    As far as battery brand, it's difficult to go wrong with the big names - Panasonic, Sony, KTS. Make sure you buy from a reputable seller and not some random discount shop on Alibaba.

    Another option: I've been using Panasonic BR2032 in CR2032 applications (key fobs, motherboards) for some time - different chemistry with a wider temperature range and lower self-discharge rate. As always, do so "at your own risk"...

    Funny I was just asked about this. Yup strange problems on older motherboards, even some new ones that have bad batteries.
    Swap in a new battery and generally that fixes issues.
