Wire-3 Fitted For Wireless Box details

[Chris Suslowicz]

Okay, as mentioned earlier, these are some reasonably accurate sizes for the batterias I can find (or have measurements of), for the purpose of deciding what was likely to go in the trays in a wireless truck:

6-volt

16 Amp Hour - I can't find this at present.
40 Amp Hour - 9.5" long, 5.5" wide, 10.5" high. 2-pin Niphan socket to front.
72 Amp Hour - 9.5" long, 7.25" wide, 10.5" high, wing-nut terminals.
85 Amp Hour - 12" long, 7" wide, 9.25" high, 2-pin Niphan socket to one end.
100/125 Amp Hour - 15.5 long, 7.5" wide, 12" high, wing-nut terminals
170 Amp Hour - 15.5" long, 7.5" wide, 13" high, wing-nut terminals

10-volt (Used with early wavemeters and Lamp, Daylight Signalling, Long Range.)

16 Amp Hour - 11.5" long, 5.5" wide, 9.25" high (missing) sockets for 4V and 10V on end.

12-volt

14 Amp Hour - not got, but for WS62 with 2 rubber sockets on front face.
22 Amp Hour - 12.5" long, 5.5" wide, 9.75" high. 2-pin Niphan socket on front.
75 Amp Hour - 15" long, 7.5" wide, 11" high. 2-pin Niphan socket on end.

The 16 AH batteries are made up of individual "Cell, Secondary, Portable, 2V 16AH" connected together with 10 SWG copper wire links. (Not the usual poured lead permanent connections) The 6V unit has a Niphan socket and the much older 'pair of brass socket contacts' in the end wall of the case - that system started in WW1 or before. The 10 volt unit only has the old type sockets, which are unfortunately missing from my box. (Pin diameters and spacings varied to protect equipment from mis-connection to the wrong voltage - unlike the WW2 "one niphan conector fits both 6 and 12V batteries"!)
