I'm gonna agree with the others here who place the blame on the meter, not the battery.

My Fluke 87V that I bought two years ago is still on the Energizer battery it shipped with.

As for brands, I've pretty much completely switched to IKEA alkaline batteries. They used to be made by Varta, though they no longer carry any OEM info. But they seem to work well, and they're a fraction of the cost of name-brand alkalines. So even if they only lasted half as long they'd still be far cheaper, but I haven't found any perfomance issues with them at all. .

ali6x944:
I generally try to avoid the use of alkali cells because of their  horrible leakage and crystallization problems...
So I would rather use a rechargeable battery or carbon-zinc battery aka heavy duty batteries because they are less prone to those problems and for carbon-zinc batteries they are much cheaper that alkaline batteries.
But it must be noted that the average capacity of the carbon-zinc batteries is a fraction of the poorest preforming alkaline...
A good source of info in this subject is this website:

Jester:
My early 90's Fluke 87 eats batteries for lunch (every 3 months or so). I rarely use it because I have multiple 34401's on the bench and it seems like every time I do power up the 87 it needs a battery.

Audioguru:
I notice that Duracell and Energizer cylindrical No-MH rechargeable batteries are both made in Japan (maybe by Panasonic/Sanyo?) and Energizer 9V alkaline batteries are made in Germany (by Varta?).

I avoid Duracell because of their proven track record of dismal failure. So I bought a store brand alkaline 9V here in Montreal, it's the brand of a big chain pharmacy. It's usually good stuff.

This morning the DMM was dead. I took the battery out and measured with my analog meter and it's 0V. Flat line. Took the battery apart and it's 6 x 1.5V cells and they're all covered in white corrosion.  >:(

We're talking 6 months here, with very little use.

Think a minute. Is there any other reason that a battery could be drained unacceptably quickly? If so, why have you discounted the other reason?
