I found the size and low voltage of this battery quite curious. It was in a box of new-looking units at the local tip-shop. Just 1.5V but 250Wh.



Here's the manufacturer's page.

It looks like a modern equivalent of a "Flag Cell", as used in telephony (particularly local battery setups) in days gone by:

Even so, 250Wh when converted into the more familiar Ah is 167Ah. Most car batteries are around 1/2 to 1/3 that, though at 12V.

As it's called a 'Datacell' which implies RAM memory back-up, WOW! That must have been one heck of a memory array!

This appears to be their very simple web-site...

My first thought was also a latter day FLAG cell but clearly not so.

Looks like they're designed for some specialised applications where a battery change would be very hard: http://www.datawell.nl/

Wow, a Dutch company and specially made French batteries. This makes me proud of Europeese cooperation. Apparently batteries "Made in Brittain" are no more needed. They can go out.

Got some useful info from the page. Thank you!
