Is your a rechargeable Battery?

All of the ones i have seen and dealt with have had a cover that comes off and you feed the beast 16 D cell batteries.

The PX-300 uses the same battery as the older PT-400. Sometimes it's easier to locate PT-400 batteries in catalogs than it is PX-300. There are both nicad types and dry cell types. It takes some bucks to fill up the D cell type box with alkaline types!

Sorry about resurrecting a ten year old thread. I'm searching for a PX300 battery case.
I own a working PT500 and a few PT200's. I've noticed the battery for the PX300 is about an inch smaller in width so I'm in search of a PX300 battery.
It does not matter if it's dry cell (D cells) or a rechargeable battery. I'm only interested in the battery cabinet.

Thanks,
Tim

I don't know if this might work for your application but I see Ebay has some PT 300 stuff.

Hey Andy.

Thanks for the eBay tip. I decided to buy another this time complete with the stock alkaline battery pack. The only other solution I came very close to attempting was modifying the lid from an ammo can.

Now I have to find someone who can burn a PROM for it. I doubt the Moto shop I dealt with in the 80's still has their programmer.

Thanks again.
Tim

Re: PT400 Battery.

Hi,
I own a crystal controlled PT400 which sort of contributed to my initial mistake of buying a PX300 radio without determining if the battery was compatible. When the PX300 arrived I found the PX300 was about 2" longer than the PT400. I recently bit the bullet and bought a full unit with the D battery container only to knock it off the kitchen table and shattering the battery box. I now have three PX300 radios. Retro-fitting a battery container should not be too difficult. I have not attempted it yet but a M19A1 ammo can fitted with a 9-pin D sub connector is the perfect width and would serve as a sturdy metal replacement battery enclosure capable of housing a rechargeable sealed lead acid battery .
