I Hate Batteries

Or another thing would be for devices to be designed around the voltage of rechargeable alkaline replacements instead of non rechargeable. The lower voltage of Ni-MH compared to alkaline usually means the device won't perform or last as long as it will hit the low voltage cut off sooner. Especially devices that need 4+ in series as the voltage drop adds up. I try to use rechargeables where I can though. There are places I found where they just don't work, like Wii remotes. Would be interesting to see if you could retro fit lithium ion in those. Not sure what the voltage tolerance is though. A single lithium cell is going to be a little bit more voltage than two alkalines and it might not like that and it might let the magic smoke out. :o

You know, if you have a lathe, you can actually get an E-cigarette battery that fits alongside additional circuitry in a package as small as AAA.
Also, Chinese make lithium battery that act like AAA but are chargeable via usb
also, since this is an EE fourm, you can always look on other threads and learn how to convert wiimote to usb rechargeable,internal but swappable lipoly based controller

I hate how you have to worry if they are going to work and about when they are going to run out. The voltage testing. The leaking electrolyte in my damn Garmin. Ugh. :horse: I've recently dealt with multiple car batteries dying due to age and failed auto electronics. Also we've got a young child at home and they have many battery-powered toys. We buy great bricks of alkaline AA & AAA cells every other time we go to the store.
I have to thank Jogri for his post in this thread. I've just ordered some rechargeable AAs and AAAs. I forgot that I've already got a nice Powerex charger and I also noticed that my new R/C-vehicle-battery charger will apparently charge any rechargeable battery chemistry. Yes, the ISDT chargers look nice.
Now, I have been softening. I used to love my pneumatic impact wrench (AKA rattle gun) for removing lug nuts, but a cow-orker sold me on cordless. He went Milwaukee 12v and I went Makita 18v. My god, these are handy as hell. I use my Makita impact driver and Makita LED flashlight every single day. A charge lasts months (I bought the big-mama packs) and recharging is quick and painless. I guess I'm totally OK with the Makita 18v system but I still hate AAs and AAAs with a passion.
I didn't realize that Fluke DMMs had low-battery indicators (yes, :palm: if anything had one, it would be a Fluke DMM - thanks eevblog forum!). That makes me feel better about the 9V batteries that have been in there for years (I still check them annually for leaking electrolyte)

No cordless drill can compete with my 900W dewalt drill. Similarly, Corded tools often are more durable and powerful than cordless ones. If you don't have outlet access everywhere you stand, either you're limited by law, or your house design was bad. (I have so many outlets, that if the government were to know of it, they'll start charging me industrial rates, despite the fact that I consume the least in my locality)

Probably 99% of THOSE batteries are SHIT ones that come with the device!
Probably 99% of people have SWAPPED those from other less used Remotes!!
Probably 99% of people have 'AA' batteries as spares, rechargeable or not.
Probably 99% of peoples Rechargeable 'AA's are flat, & can't find the Charger!

That's why, switch to using phone with Ir blasting capability, Like an samsung s4, be it 24x7 offline for security and single purpose only, since it's too old to do anything else.

On planet earth we use drills outside our house as well :)

I think cordless tools are work especially grinders for hot work and working around welding type stuff (so many burrs and filings and dust and crap the extension cords are a hazard). Downside you need a few expensive dewalt 60V batteries to do a reasonable amount of work.. or just take breaks since its extremely nasty work
I kind of see how many pounds of freaking material the people that complain about battery tools in non production jobs have to grind! These people must be repairing earth movers and fixing battle ships!
I think some people still have PTSD from brushed motors + nicad
Brushless lithium tools are GREAT. And you learn to work efficiently (hold grinder correctly, check to see if the disks are in good shape). with a cord you can sit there all day doing nothing on a flat wheel. If you need a really strong drill chances are its not the right tool for the job (i.e. use a magnetic drill).

20 years ago my father gave me a corded Makita impact drill, which was excellent for the masonry work that I needed back in my home country (where houses are built the way they should). Fast forward many years later (and living in the US), he gave me a Hitachi cordless impact drill, which is quite excellent for various jobs, especially in the tight spaces in the attic. However, in the rare occasions I need it to actually go through a masonry wall, it loses to the Makita by a large margin.
Anecdoctal? Yes, but that shows me that both have their place. :-+
(BTW, the Hitachi came with a pair of batteries - a life saver!)
ogden:
Today better pair is decent brushless impact drill for "everyday jobs" and corded SDS+ hammer drill - when you occasionally have to "go through" masonry/concrete/brisks. There are excellent cordless hammer drills as well like Bosch GBH36VF-LI, but price is prohibitive for home users.
