1.5V cell Type 5S/2000
Can anyone help in confirming the dimensions of a dry cell with an Air Ministry designation, 1.5V No. 6, 5s/2000 please?
These were used in Test Meters Type 'D' made by the Automatic Coil Winder and Electrical Equipment Company (AVO). The cell is of square section, has a single central screw terminal and a flying lead and is likely to be one of the following sizes: 1 3/8" square by 4" - equivalent to GPO Type DS6 (170754) or 1 1/8" square by 3 1/4" - equivalent to Ever Ready R1226/Siemens Size 'T' both sizes excluding the terminal. Even better would be a scan of the case of a 5S/2000, but maybe that's just too much to hope for. Peter M. Munro |

Re: 1.5V cell Type 5S/2000
Peter, might be worth sending an email to this guy http://www.vk2bv.org/radio/avod.htm It sound like he might still have the original battery? Maybe he could be persuaded to scan the 6 sides in a 'non destructive' way?

There are links to several military battery specs here:-

Re: 1.5V cell Type 5S/2000
Your description and dimensions sound very much like the Exide B23 which I have (see below). Presumably this is the civilian equivalent of what you are seeking.

Re: 1.5V cell Type 5S/2000
Is it identical to that batch of X cells I made for you, Dave? Only difference being the flying wire instead of another terminal?

Re: 1.5V cell Type 5S/2000
As you will see from the picture below of the B23 alongside an (original*) no. 12 battery (or X cell, as you know them), there is quite a difference in size.
The B23 is large enough to stuff with a "C" cell, whereas the no. 12 takes a "D" cell. *the reproductions are all inside field telephones and I was too lazy to open one up when I happened to have an original to hand.

Re: 1.5V cell Type 5S/2000
Well, so much for shortcuts...
I'll have to see what dimensions are from my data. Bill

Re: 1.5V cell Type 5S/2000
Sorry, Peter,
Murphy reigns triumphant (when not ?). As part of my "downsizing" I junked them both a month ago (they'd been sitting, unregarded, in the museum for two years !). They WERE 1/8 and 1 3/8 square, and one did come from a Model D. You really MUST learn to be more clairvoyant ! |

Re: 1.5V cell Type 5S/2000
Can you clarify the height please?

Re: 1.5V cell Type 5S/2000
Thanks for your interest everyone. I was trying to explain what I need without using too many words which may have caused some confusion, so I'll try again.
The replacement cell is for a Type 'D' Avometer which I'm restoring as a gift - I have several of my own in various states of repair. From one of these I have a GPO cell, Type DS6, the one with the larger dimensions, 1 3/8" square x 4", with a central screw terminal and a flying lead. From other Avometers I have some Ever Ready Type R1662 (1 1/8" square x 3 1/4") also with a terminal and a flying lead. This I gather is equivalent to a Siemen's Size 'T', and now from your information, an Exide B23. Almost certainly, one of these sizes is equivalent to the 5S/2000, the type mentioned on the instruction plate, but I don't know which and that's the first thing I need to know. Then ideally, I would like to have a scan of a genuine 5S/2000 from which to make a replica. If I can't find the real thing, the pictures which you have posted, and the link to the Mil Spec site give me enough information to make up a print of something like how it should look. Thank you all again, and best regards, Petr M. Munro |

Re: 1.5V cell Type 5S/2000
In case it is of any use, here is a scan of the B23 case opened out. I can send a higher resolution version by email.

Re: 1.5V cell Type 5S/2000
With the help of the information which you kindly supplied and by comparison with a No 12 cell, I've drawn up what I hope is a reasonable replica of a 5S/2000 No. 6 cell.
The pictures show the construction which is intended to allow the 'C' cell on which the replica is based to be replaced. The top cap which, in the original was pressed onto the carbon rod is the head of a cheese head screw drilled and tapped, leaving a slot for a split screwdriver blade. With this slotted nut removed, the battery carrier can be withdrawn from the case. After assembling the case, the cardboard was dipped in molten wax to reproduce the original waterproofing. It is show beside a real No 12 cell for comparison. I don't know if Crompton Parkinson worked seven days a week in 1945 or not, so the date, which the final tester stamped slightly off square and with less force at the right, is a Thursday. PMM |
