Mega sized accumulator

Post by Mike C » Sat Jan 12, 2013 4:55 pm

This is a Chloride make glass cased accumulator for industrial use and these were not used in radio. Such uses were emergency lighting and for back up power in cinemas. The cap has Exide on as both firms were connected but back in those days Chloride owned Exide. I have never seen an accumulator with embossed lead plates before as my others just have the name on the glass.

They went on to make a plastic cased version later on of this size battery.

What size & weight is it?

 

Re: Mega sized accumulator

Post by Mike C » Sat Jan 12, 2013 5:31 pm

Its heavy but have not weighed it. I have a copy of the instructions that the seller kindly did for me. He had them on Ebay but they did not sell and it was local to me so he kindly gave me these for nothing. He has four more but there spoken for. They are designed to be used in series as per pictures. They may be 2V each but not sure.

If it's lead acid as it looks like, then it's 2V. Only the capacity in AH and the output current capability change with the size.

Unless there is more than one cell of course.

OT, I realise, but a few years ago I visited the US lab where they were developing this laser http://news.bbc.co.uk/1/hi/sci/tech/6380789.stm. As it says in the fine print, it is battery-powered. The four Li-ion batteries which drove it were each about the size of a 4-drawer filing cabinet, or maybe a little smaller. Between them they could deliver more than a megawatt of average power for 10-20 seconds 8)) . I was impressed. To be fair the laser was impressive too.

So what *IS* the W x H X D?

 

Re: Mega sized accumulator

Post by Mike C » Tue Jan 15, 2013 12:26 pm

I did trawl through a few sites on derelict places and one site shows these batteries being used in a cinema. They were wired in series on racks, possibly emergency lighting or a back up power source. Some mining buildings used these as near where I live I found some plastic remains of this size battery made by the same firm and the site in question is the old Marley hill pit which closed in May 1983. I guess the glass ones date from the 1950s??. There is no date on the instructions though.

I have a couple of these in the garage. There were 7 of them wired in series for emergency lighting. I still have the charging plant.

 

Re: Mega sized accumulator

Post by Mike C » Tue Jan 15, 2013 3:16 pm

Are they glass or plastic?. I have never seen a charging station for these. The plastic ones had plastic separators between plates where as the glass type use wood separators. The ones I found at marley hill had been smashed sadly to get the lead plates out.

I have a few large Exide cells and an Ever Ready and smaller Exide sizes such as DFG and DTG. Those large Exide cells were not for radio but emergency lighting so the seller told me.

These are very large glass types made by Exide.

I have a few more and the DHG one is huge but sadly missing its insides. I dump dug this.

The empty one looks like the ones i have.

 

Re: Mega sized accumulator

Post by Mike C » Tue Jan 15, 2013 5:02 pm

To big for radios though, Its a shame my DHG is missing the insides but looking at the shape no separators were used and would only have two thick plates like the smaller ones, a lot of the radio ones were of this construction.

Most common size used in early radio giving LT voltage to valve heaters.

75 AH was common Radio size for the 2V 100mA, but earlier valves might have used larger.

Mind you the largest LT drycell maybe more than 70AH ( 8 x F cells in parallel also AD3 and B137 had 8 x F cells.)

 

Re: Mega sized accumulator

Post by Mike C » Tue Jan 15, 2013 6:21 pm

The only battery I know of that uses eight F cells is the 911 6V or in modern terms the 4R25-2 each four lots of cells are wired in series then both joined in para but not seen a 1.5V one like this before. That said in the old days there were many sizes made and shapes to and cell arrangements but with LT batteries the name of the game was to make them last longer and to do this cells were wired in para and the AD14 is a good example of this, this battery fitted the Ever Ready briefcase N radio and powered the LT side.

AD14 I'm convinced is 6 x D Cells, maybe same as LT part of B103. I suspect the HT only B107 is the HT part of a B103 combo.

US Eveready (NCC/UC) No. 745 LT battery is 8 x F cells. The US had a lot of radios with big packs.
8 cells in a row. So about 240 x 95 x 32 I think. I have a photo off the Internet.

AD3 is 8 X F and 60 x B cells (250mA filament)
B137 is 8 x F and 60 x Biscuits of PP9 size, so more HT capacity (Sky Prince 15mA + 9mA or Monarch FM at about twice LT & HT)
AD34 is 83 x 140 x 70 @ 1.5V. Don't know what was in it. Must be enormous!
AD4 is 4 x F cells @1.5V and is 64 x 95 x 64mm. Similar size to 996 (6V)
I think there is a pack twice height of AD4?

Lantern battery is 6V, 8 x F Cells, equivalent to 2 x 996

Spot on there Michael :thumbr: The AD14 is made up of six C cells in para and this battery fits the Ever Ready type N radio but not sure what others it fits.

The N3 :)

B107 & AD14 seem to be the B103 split to make a Briefcase. Of course on the N3, you only replace the AD14 half as often.

I've been creating Batteries on Radiomuseum.org
I've done a lot of Ever Ready and linked some radios to them
Also some Vidor

One Pertrix/Varta and one or two US Eveready

Lots to do and finding eBay photos or others with permission is a lot of work

Siemens http://www.radiomuseum.org/m/siemens_d_en_7~typ.html


I should do Eveready/NCC, UK Exide, GEC, Siemens, Burgess, RCA etc too ...

You have any photos you want to share and have free membership?

The N3 was a different colour and I think it had a brown faceplate rather than the grey but there was a white faceplate model to that's not often seen, confusing. It sounds as though there is an N1 N2 N3. I have the grey faceplate one type N.

I have the official Ever Ready Service Manual for N. There is a page labelled Supplement for N3

Both I think come in at least two colour-ways.

N:

DK91, DF91, DAF91, DL92

Cord only on one side of scale, pointer attached only one end.
Switch near opening and on chassis.
(see Arrows)


Metallic finish to plate common, single tone snake effect, but there is a 2nd version.

N3:

DK96, DF96, DAF96, DL96

Cord is on BOTH sides of scale, pointer attached both ends, cross over of cord on back of scale.
Switch near hinge, on case, not chassis
(See Arrows)



At least two different styles of scale print.
Grey OR cream plate on Red & grey (or White?) two tone cover is common
Grey cloth is bobble pattern

Some great work there Michael :thumbr: When I took some of my batteries apart I sent the scans to Batterymaker, that's Bill Morris but that was a few year back now and sadly I don't have copies but he will I am sure. Is he on here because he does batteries from scans and photos and he also does graphics to from photos.

He did have an accident and lost some of his files. Some are on the Thomson Family site, but seem to be a bit inaccurate.

 

Re: Mega sized accumulator

Post by Mike C » Wed Jan 16, 2013 12:44 am

He may have hard copies knowing Bill, he was on the other forum a while back and he has loads of scans of batteries for radio. I have seen a few sites with battery scans on and the Thompson one has been on there ages. Bill also has battery books, lots of them which list dimensions and voltages to from a few battery makers including British and American. He did some Exide ones as he has videos on Youtube.
