I practically live on batteries here. Everthing has a battery. Sure, the oven and refrigerator and TV are AC powered but most things need a battery. I have recharageable batteries for almost every minor thing in the house though.
I have flashlights, wall clocks, kitchen timers, weather stations, a cordless vacuum, a laptop, a cordless leaf-blower, a cordless hedge-trimmer, cordless tools, and portable stereo radios all over. So I have rechargeable batteries for almost everything. I am building a shelf in the basement dedicated to recharging things.
But there are some annoying devices that use those little round batteries. Kitchen timers mostly, but even a caliper needs one. I hate that there are not rechargeable versions for them.
Two kitchen timers and the calipers all went dead last week. So I set out to get new batteries. First, I discovered that the 3 stores I went to do not stock the kitchen timer batteries, but they could be ordered at 2. The batteries cost more than the timers. I can buy new timers cheaper than the batteries. That makes no sense.
So I will buy slightly more expensive timers that have batteries of a type that I can replace with rechargeables.
The kind that fits my caliper comes only in packs of 3. The battery lasted 10 years; the shelf life of the replacement battery is 3 years. I will never need the other 2 batteries! But the joke is on them. One of the batteries in the 3-pack wasn't even the right kind. Same size wrong voltage.
Yeah, OK, the joke isn't really on them, but the error costs me nothing as the last battery of the 3 would be long-depleted natuarally before I needed it so I could just throw it away and no loss.
We need rechargeable small round batteries!
