I've only ever seen batteries leak when they are flat, so for something in daily use probably not an issue - I do always take them out of stuff I don't use often.
Good point about the replaceability of a PP3 connector.

I have bad experience with AA and AAA cells and have seen several badly damaged instruments because of leakage batteries. Some of them where destroyed beyond repair. Last case was my Fluke VoltAlert 1AC-E II, a voltage tester for electrical stuff. Bought before 2 years, seldom used, laying in a shelf. Original AA batteries, usable until 2022. One of them was leaking and messed up the complete tester. The other was in 100% full charged condition.
Same happend with several other gear in the last time.
We are living in the year 2018 now and have still to life with leaking batteries...
On the other side I have never seen an Instrument that was destroyed from a 9V Batterie. So These cells are the most save solution and I cannot understand why some People prefer AA and AAA cells in measuremt instruments.

AA and AAA have mugh higher power to volume ratio, and lower internal resistance.
I wonder if anyone has successfully claimed against a battery manufacturer for leakage damage.
Maybe instead of useless Batterizer sleeves, someone should make a "battery condom" for leak containment.
Maybe there could be some sort of chemically treated paper that could be used to neutralise the effect of leaks

As it is, unable to use the meter when charging that odd ball battery, lens is easy to scratch, typical UNI-T ESD problems etc, I give it a no go. On the plus side, I like the Fluke 289 interface and the fact that they out right stole it. They even improved on the 289s UI in some respects. The meter is very stable with temperature. Graphing and boot times are much better than the 289. Like the BM869s, the 181A also has two thermocouple inputs. The bargraph is one of the fastest and is bidirectional. That is just slick.

I'm liking the UT181A a lot too. With the 3rd party logging software it's even better. Allows for downloading data out of the meter and automatically exporting it to csv as well. Something that the horrible Uni-T software doesn't do. That battery and charging sucks though.

None of which really matters for a multimeter.
(Does anybody here change the batteries more than once a year in a meter with LCD display? Mine last for years...)

Isn't that what most decent 9V batteries are, 6x1.5V batteries in an electrolyte containment sleeve? :popcorn:

I did, with local Energizer representative few years ago when it ruined my LED flashlight, back then LED flashlight was still a niche product.
Ended I gave up as it seems like they deliberately put tons of red tapes that took me 3 or 4 months just to get the confirmation whether my claim was legit or not. I stopped pursuing the replacement procedures. :(
Now, alkaline cells are permanently banned in my T&M equipments. >:(
LeonR:
I see a lot of comments on US and Europe-based brands, but very little for the Japanese. Kyoritsu, Hioki and Sanwa seem to have products high end specs. .. is there something about them that make them not stand in the same tier as other brands?
