Well, voltage readings were spot-on (+-1 count) after 8 years without any calibration (guess it's not too hard make an accurate 2000 counts DMM). Actually, after my own calibration it become worse :(. So, a totally usable device to me when resolution is not needed (most of the time for me). And yes, I used it on mains as well, although I hesitated holding it in my hands. But it did the job well.

Wow, that's too good to pass up. Ordered one. Of course this means I'll have to select something of my own to donate to a hacker/maker space.

23A 8 x 28mm
27A 10.3 × 28.5mm

Thanks, glad I read this before ordering a container full of LR44s on a slow boat from China :D

You can also check the prices of the original type in your stores and on eBay. They don't seem any more expensive than 9v.

This would be the perfect base for a cheaper EEVblog branded multimeter.
His official BM235 meter is a whopping AU$150.00, who knows how much that's in real money.
And it doesn't even come with a cool pouch! Doesn't that violate Australian law?

Something like LR44s. Check actual size before ordering.

Under 50c US retail here, and if I buy the Energiser version they are $1.50 each at Wallyworld. I buy them in strips of 5, and in a remote control they last around a year, just like the name brand ones. The expensive ones are the 7V5 5 cell ones that are used in certain remotes, or the CR1620 that car OEM fobs use, that are integrated into the key itself.
The A23 packs are a lot cheaper than a 9V pack here, which are at least $3 each retail, and if you want Energiser or duracell they will knock you back $5 or more each. You can get the OHL versions of the 9V brick, but they are more sawdust and air than active chemical, and are around the same capacity as the A23 pack in use. you really want to pay buy a PM3 brick, those are often over $5 for the cheapest ones, I got the branded radio which uses them for $3, no battery but I found a used 9V wall wart to power it instead.
