RTC Battery for HP EliteBook 820 G2 ( 702853-001 ) where to buy?

[car23]

We recently received a batch (more than 50 items) of old HP Elitebooks as charity donation (Mostly 820/840 G1/G2/G3) in various configurations and conditions.

We bought SSDs to refit the devices and installed a fresh Windows 10 on them.

Sadly some of the RTC batteries are empty and the devices display the usual warning from the BIOS along with windows mentioning an expired password (although password expiry is off). Since we are planning to donate those to children for homeschooling it would be nice to replace those prior to handing them over to avoid the usual hassle for the children.

The manual mentions  702853-001 as spare part number:

I tried to order those at local retailers but always received CR2032 which do not fit (too thick causing the keyboard to bump up). It is nearly impossible to get CR2320 replacements with an attached cable:

Is there any recommendation where to buy those in Germany for a reasonable price?

To emphasize this once again: I am looking for a non-profit charity club where all the cleaning, refitting, installing and stuff has been done unsalaried already.

It is available from HP

         https://partsurfer.hp.com/Search.aspx?searchText=702853-001

and it sells for around $35 each. You can search on eBay for around A$7.00 or GBP 3.99 Approximately US $5.47 each.

I've found them BUT Admin sent me a PM saying "I'm not allowed to post those links". Please search yourself.

Regards.

Thanks @Banhien - I only get used items at ebay and some claiming the HP part number 702853-001 but listing CR2032 or 3.2mm thickness  in the specs (like 324656177995) which will not help me with the keyboard issue...
