good 9V battery

<< < (6/11) > >>

Nusa:
If whoever designed the meter chose an inadequate power source for their design, that doesn't transfer any blame to the battery itself. So long as it's delivering what it was designed to deliver, it's doing it's job.

HKJ:
For comparing voltage from different types of 9V batteries I will suggest my comparator:
http://lygte-info.dk/review/batteries9V/Common9Vcomparator.php

It includes most 9V chemistries and types, including 3 different LiIon batteries, Zinc-Carbon, Alkaline and both 7 & 8 cell NiMH

EndlessSummer:
Ahhh, yes....
The thread is dead as the batteries it's about.
It's the only one that came up in my google search for Carbon Zinc battery usage in the Fluke 87 series meters though.
Does anyone happen to know the reason behind Fluke's specifying Carbon Zinc batteries for these meters?
Thanks

They *allow* you to use not only Alkaline but Zinc-Carbon. User manual of 87V says:


--- Quote ---Replace the battery with a 9 V battery (NEDA A1604, 6F22, or 006P).

Specifying NEDA A1604 w/o letter suffix means that you may use any type: Alkaline, Zinc-Carbon and Lithium (non-rechargeable).

richnormand:
before blaming the battery it would be useful to ascertain that the meter has a hard on/off switch that completely cuts off the battery circuit. If not, you will have to measure the standby current.

Years ago I had a cheap LCR meter that would eat batteries, even if I was not using it much. It had a soft "on" switch with an auto-off feature. The culprit turned out to be a leaky electrolytic capacitor that was continuously draining the battery 24/7...
