Let’s talk Batteries
While I was sleeping… batteries changed.
If you still pick up the same old at the battery kiosk in the big box store, knock it off. Batteries have changed and retailers/manufacturers aren’t about to clue you in.
I use batteries. Not a lot of batteries, but I have a cordless phone, camera and an assortment of remote control units. I have an indoor/outdoor temperature gauge and a remote electricity use sensor on my breaker box that talks to my computer.
I use batteries.
New cutting edge batteries are rechargeable Ni-Mh LSD. If you went where I did when you heard LSD, you are unforgivably old. Get over it. The acronym now means “low self discharge”. That means if you throw them in a drawer for three to five years they keep a charge and still work.
Sanyo Eneloop batteries, for example are billed as rechargeable 1,800 times. Let’s say the batteries in your TV remote last a year, (mine do). If I recharge those same batteries once a year and reuse them I’ll need to buy new batteries in the year 3,814…
What if Sanyo is exaggerating and the batteries give up the ghost in the year 3,000? Caveat emptor? I’ll probably get over it.
Sleeves are now made that fit AA batteries and adapt them for use in things requiring D or C batteries. I find this quite convenient.
Let’s look at how you stuff electricity into them. Chargers have changed too. The new chargers are “smart” chargers. The batteries are “smart” too. This just means that a chip has been added and charger and battery can now communicate. Smart chargers know how much charge a battery needs and when to stop. The best of them have a refresh mode to extend battery life and batteries no longer need to be charged in matched sets.
There are some fancy battery chargers out there with more bells and whistles but a $30.00 model does everything I need.
Perhaps most of you knew all of this already? It was news to me last December when I started reading up on battery technology. I may never need to buy a battery again…. 😉
