I Hate Batteries

<< < (6/20) > >>

coppercone2:
when you first realize you are totally surrounded by franken batteries reminds me of the scene from platoon where the perimeter is over run. You start opening things up, counting, doing some math.. the numbers really never come out good. Then you keep finding stuff you forgot about.. then it turns out 3 objects leaked, you don't know how to clean it, get a bunch of repair jobs on your mind and you are stuck inside because of COVID19.

I think its just a panic attack

and its vietnam because those people have snakes everywhere! looks like AT&T. Do a little bit of home repair and it looks like the thing is growing in there infesting the floor because everything is corded. People walking around tangled with wires 2 power tools in the hands that shits crazy!

The solution is ....
Panasonic Eneloop   :-+ :-+

A bit pricey, but they just last

/Bingo

Ps: I might have to look into the IKEA LADDA , but they compare LADDA to Eneloop Pro ...
Strage as Eneloop Pro is spec'ed for 500 charge cycles , and LADDA for 1500  , Normal Eneloop are speced for 2000 cycles

 Nearly every device I can think of in my house that uses replaceable batteries takes either AA or AAA. I have a flashlight that can use 2x C, but it came with adapters in place which each hold 3x AA in parallel. It's an LED flashlight, so they last fine. AA for the laser in my saw, AAA for the TV remote, at home I don;t use a wireless keyboard or mouse, why bother? I rarely use my old Fluke 8060A which takes a 9V, it needs another shot at repair to make it usable again anyway. My newer ones are AA and AAA. I'm trying to think of something that uses a different size and am coming up blank at the moment.

Okay, that's a rather unpleasant story. I'm talking specifically about my UT-30 (succeeded by UT-33 these days). I haven't really tested every damn function under mild undervoltage conditions, but I have never had problems with it unless using it for several days after low battery warning.

The warning appears at about 6V, still giving the good old ICL7106 ±3V rails to work with. I think it would be fine. As an aside, the warning is generated by the 7106 itself which means they use not just a clone but a somewhat improved one.

Speaking of batteries, I have a few 8.4V NiMHs for that sort of devices. No drama: low battery warning shows up, I put the battery in a charger for a few hours, problem solved.

I have a vintage Sangean shortwave radio that takes 3 D batteries in addition to two AA batteries. I also have virtual walls for my Roombas that each take a pair of D batteries, and my wireless weather station consoles take C batteries. The virtual walls are the only thing I use real D batteries in, everything else is Eneloop AA's in adapters.

I've even got LSD NiMH "9V" batteries in my smoke alarms, whenever the first one starts to chirp I cycle them all through the charger, works out to about once every 9 months. I don't even remember the last time I bought disposable batteries, they're obsolete IMO.
