UK battery suppiles

. . . . not learn something new every day, in this case, but learn something old . . . . .

I also avoid Duracell alkaline manganese for the same reason. Amazon do seem reasonable. I recently bought a couple of boxes of Amazon Basics 2400mAh NiMH cells and tested one box because I wanted to make up a set of 6 closely matched cells to use in a resistance tester. Here are the results:

I forgot to mention that the Amazon Basics 2400mAh NiMH cells make the following claim: "Maintains 65% of original charge after being stored for 3 years" which suggests that they are Eneloop or equivalent. John

Your fridge must be ancient. Ours have been frost-free for many decades. The Samsung is great. Well, except for the stupid icemaker; I ripped that out to make more freezer room.

The power failures are caused by the California greenie crazies, and our rich gourmet airhead governor.

Sure, nobody needs a garden.

Did you factor in enough batteries to get you through a few of weeks of winter gloom? Or even a few days of network collapse?

How much power can you get from "a small windmill" ? Average 50 watts?

I trust that the royalty of Europe, or maybe the Russians, will cut off your gas.

Trying to punish the Russians with sanctions has punished the Germans a damn sight more! I don't think their government gives a damn if the people there freeze to death over the winter.

Thanks for the compassion, but in this year's first 3 quarters, abt.

No need to rely on Putler and his orange fan boi.

Chinese watts? At what wind speed?

First, pay us for the two world wars and the Berlin airlift and the Marshall Plan. With interest.

Here's hoping your coming winter will oblige and be sunny and windy, then! ;-)

I don't laugh, I used that iron once. Horrible job. I think I was trying to repair the connections to a motor in a toy. Soon after the school got us into some training, and they made us buy an electrical iron (75w) and taught us how to solder.

Years later I asked a friend how to properly solder on a PCB with a much smaller iron.

Please don't say that! I'm still cringing in pain at the thought.

I remember once (I might be 16) I was repairing a toy for a small kid, soldering the motor cable or something. I had to leave the room to fetch something. I said sternly "don't touch it, it burns!". I came back, he was not there (which was strange, he was fascinated by the job), so I continued and finished it. Minutes later comes his grandmother asking if I had some very hot thing, his grandson was hurt.

We figured out he had grabbed the metal part. He understood the tip was hot, but he thought the metal would be fine. He was adamant he had not grabbed the tip. Why did not he grab it by the wood handle, as he had seen me do, I do not know. I was not punished, but grumbled at. The poor kid was crying in pain and shame.

The type that heat a wire loop in seconds, via a large current? Not me.

Layer construction. That was why the PPn series of batteries was developed, because layer cell technology allowed more useable energy to be stored in a given volume, compared with cylindrical cells.

As the battery manufacturers didn't publish electrical specifications, we have no way of comparing them except by individual experiments or hearsay.

My brother-in-law was the first person to import them and gave me two sets of 6 x HP7 (U2) to test. I put one set into a portable tape recorder and left the other set on a windowsill. Both sets were leaking profusely after about 6 months.

I use a suede shoe brush on my Weller, it wokrs very well. 'Savbit' solder, which was saturated with copper also helped prevent erosion of the bit. The most recent reel of 'Savbit' I bought from Farnell seemed to be causing erosion, so I had it tested by a chemist friend - it contained no copper at all.

The soldering gun tips eroded fast.

My Metcal tips last about forever for some reason, and I use 63/37.

Curious!

A friend long ago had one and loved it. I had doubts about voltages in the PCB. So I never got one.

That's why I see so much military in our town. Looks like we have elected a dictator wannabe.

OMG. A shithole full of lies ahead. Thanks for the warning.

DiodeGoneWild does. He is very competent, and has a nice accent, but doesn't care about the appearance of things, or fancy tools. He has a very pragmatic attitude to health and safety.
