Yeah. I have one meter that uses a 9V, which lasts about a year if I put an alkaline in there. A lithium will last 3-4 years, typically. I don't use that meter much lately as th

I rather doubt that. Thickness of the plates bears directly on the reserve power spec, while the number of plates bears on the CCA spec. What I was dealing with was made by Exide, not made in

Are you sure?? I never saw anything suggesting that.? I can't say for certain, but I am fairly sure they do not. I was wrong about their shelf life.? It says 20 years, not 10 or 15. Andy

I think we are getting hung up on technical definitions that were not used in the real world. A carbon-zinc is classified as a Laclanche in all my battery books. [can't add the diacritical above the

I wrote: Sorry, I take that back. It depends on which store I go to.? Where I shop most frequently, Energizer fills most of the racks.? In another, it's Duracell. But not the Eveready brand

That bit with the glow plug was back when I was in high school, *MANY* decades ago. Lithium AA cells weren't around back then... -- Member of the toughest, meanest, deadliest, most unrelenting --

Andy, The cell or battery is charged, for example, for a minute then discharged for a second and continuously repeat until charged. I have seen it apply to different cell types. Bertho From:

Now by "lithium" - do you mean the NON-rechargeable, super-long-life lithium 1.5 V cells?? The ones that cost $20 for a pack of four AA's? I use those for the outside thermometer so it won't freeze,

Interesting.? That's not what I see here.? (I stopped going to Walmart during early COVID and mostly haven't been back.)? These days I see tons of Duracell and few of others.? I'm sure each

I thought that was the key difference between Leclanche cells and regular (non-Leclanche) dry cells. Andy

The Everready >primary< AA and AAA and 9V lithiums do not have a drop down regulator. Just disassembled a dead AA and 9V. They are pricey but probably worth it for several reasons... For test gear I

I don't know, but I expect they all use crimped seals of? one form or another, and the quality of those seals (a manufacturing step where they can save money) surely comes into play.? Even if they

Try removing then reconnecting the press on RF connector. Rotate it about 45 degree each way after you reconnect it. Those connectors have an amazingly low VSWR matched by their lack of robustness.

I don't know if this is relevant.? ?But one of the stated characteristics of Leclanche cells was an initial open-circuit voltage of about 1.4 V, which rapidly falls off.? Whereas carbon/zinc dry

I'd be concerned about the word "outdoor" in that sentence. Being exposed to the elements opens up at least a few cans of worms.? Including corrosion.? Or frozen (compromised) components.? Some of

I just realized that the problem is likely just the wifi card that the antenna connects to. Problem is that it's likely proprietary and? not obtainable.

I just opened it up with a Phillips head screwdriver and all the connections look ok. The antenna connection is on the frame or housing of the camera and looks in fine shape. It travels through the

Question about the Lithium AA cells - I know they use a little buck regulator to get the voltage down to 1.5V (nominal) but that also means that they are current-limited. Finding out the current limit
