We received an inquiry from a metal detecting group who was at a WWII site. They unearthed the Philco battery you see in the photos and were curious about it. I told them of Philco's early battery history and of the switch to military gear production during the war. I suspect this battery powered one of the wartime pieces of equipment. Does anyone have any other specific info about this that we could share with the group?

Scaled to the persons foot in photo safe to safe that's a big one. I am sure there was all kinds of war materials they provided.

While a kid, in our garage there was a 12V Lead-Acid battery from T54 tank.
This job was probably 150 lbs or so, ad was 3 times longer than a battery taht would go into a Jeep Cherokee (those were much larger than the modern Japanese jobs).
We used it to start the car in winters when the battery inside the car would get anemic.

Well Philco did start out in the lead acid battery manufacturing business, and I think that they were still doing so during the war. The two materials of choice for battery cases used to be vulcanized rubber, and glass, even so that one is in decent shape for being buried in the ground for who knows how long. It could have been used as an aircraft battery, or even in a submarine, it's a 12 volt unit regardless, each cell being 2 volts.
Mike;
I have no doubt that a battery for a T54 would have been a big one, most of those Soviet tanks were Diesel powered so they needed a lot of cold cranking amps to turn the engine over.

Yep.

It had handles on either side, and it took two reasonably strong men to carry it.
We had that Soviet FIAT 500 clone for a car, and starting it on a cold winter morning (and we lived in Southern Russia!) took some doing.
The car's own battery (and we had serviceable ones, where you measure the electrolyte specific gravity and add distilled water if needed etc) would get farly anaemic, and so the tank battery would get hooked up.

Sometimes, as that extra help, some oild would have to be drained, put in a tea kettle (we had an old aluminum one dedicated specifically to this) and set on a gas stove to make it hot; then it would get poured right back, and then thet car would get cranked.
Imagine several morning in a row like this, after you get up and are ready to go to work.

Seems to me that this a general purpose or radio filament 6V battery of very high amp-hour capacity and very high "cold cranking" amps.  There are 3 cells with external bus bars connecting them.  Apparently, they brought out more than 1 pair of terminals for each 2V cell and the bus bars parallel these cells. If used for high current applications, I suspect that the battery was placed in series with other batteries.  I am not sure but I believe that many military vehicles were either 12V or 24V as many of the vehicle mounted radio equipment was designed for either 12V or 24V DC.

I can't read the lettering on the battery.  If specifically for the military, there would be a "boilerplate" stating the government agency contracting for the battery, the manufacturer and the contact number, as well as the nomenclature for the part, such as Battery, Storage, 6V 180 AH or similar to that.

The case may be "pitch".

Where is this "WWII Site"?  They did the environment a favor by unearthing the battery.  However, they need to be careful as there may be toxic or explosive material on site.

Yes, the original name for Philco was the Philadelphia Storage Battery Company.  Their second iteration.  Prior to the name change to Philadelphia Storage Battery Company, they were the Helios Electric Company, manufacturing carbon arc lamps, which preceded incandescent lamps.

From Wikipedia:

Philco was founded in 1892 as Helios Electric Company.[6] From its inception until 1904, the company manufactured carbon-arc lamps. As this line of business slowly floundered over the last decade of the 19th century, the firm experienced increasingly difficult times. As the Philadelphia Storage Battery Company, in 1906 it began making batteries for electric vehicles. They later supplied home charging batteries to the infant radio industry. The Philco brand name appeared in 1919.[7]

The rest is history.  After manufacturing batteries, chargers and "B" Battery eliminators, Philco started manufacturing radios of the TRF type, and eventually Superhets.  The Model 20 was a watershed model that helped place Philco in first place in radio sales for many years, and initiated the "Cathedral" radio style.

The most important products made by Philco during WWII were Radar instruments and proximity fuses, but Philco manufactured other military materials such as vacuum tubes, CRTs, wave meters and even filing cabinets.  The Storage Battery division was still in business in Trenton, NJ, so it is possible that Philco was producing batteries for the military, as well as for civilian use.
