Lantern Batteries

We've all seen the big 6-volt lantern battery, and I use a few of them every year, mainly to power my deer feeders.  Several months ago Milady came home with an urban legend that a lantern battery is filled with AA batteries.  I went to Snopes and debunked it.  Then told her to tell her buddies that they were full of crap.

Today after lunch, I had the grandkids helping me put a new motor on a feeder and my son determined to disassemble an old dead lantern battery.  He'd heard the legend too, and decided to disassemble a standard Duracell lantern battery to find out what's inside it.  What do you think?  D-cell batteries.  Four of them.  No kidding.

Yeah, really.  Inside that lantern battery we found four D cell batteries, some internal wiring and some cardboard insulation.    Here's a better close-up of the D cells inside the battery.

I've got a couple of D cell battery packs.  Now I have to decide if it's cheaper to buy D cell batteries, or to buy one lantern battery.  Turns out, the lantern battery is full of D cells.

It looks to me as if there are eight "D" cells in there.

At most electronics places, you can buy a 4-D clip for dire t replacement of lantern batteries. The clip costs about $5, and they go on sale for $3 from time to time.

I haven't bought a lantern battery in years.

BTW, there are 12 amp-hour nickel-metal-hydride rechargeable "D" cell out there now. With those in a flashlight, or a 6-volt clip in your feeder, you could do the whole season on one set.

I took one apart years ago and found 4 "F" size cells. You might measure the length of yours to see if they are longer than a D cell battery. I put two of the F and one C in my 3 cell maglite

6 volt lantern batteries are four 1.5 vdc F-cells in series, inserted into a case. Most folks have never seen an F-cell(looks like a longer D-cell), just like most have never seen an A-cell battery.

Many 9v batteries have six AAAA or AAA cells in them. Cheaper to use a bunch of 1.5v cells that you're making anyway (and will fit in a shell the size of the bigger battery) than to design a 6v or 9v call that's only used for that.
