Making a B114 battery.
I'm in the process of making a B114 battery for an Ever Ready model B and am very impressed with the work carried out by Bill Batterymaker1 in his earlier thread, now closed.
Here's a section of his picture 'borrowed' from the earlier thread which shows the PP3 snap connectors fitted to the wire free PCB sided box but I can't quite see how. What do the connectors look like before fitting and where are they obtainable from. I have plenty of wire ended snap on terminals but they look different, too thick and not possible to solder to PCB material. Are you around Bill, can you help. Jim |

Re: Making a B114 battery.
I am afraid that I cannot shed any further light on this because I too have the same question, this response is in part aimed to bring the matter back into the limelight again. Having seen the original article and a video I was left wondering just how the battery connections were made. In my case I would like to produce something a bit tidier than the insulating tape bound bundle currently used in in an Ekco Princess.

Re: Making a B114 battery.
At a glance they look like the insides of those plastic cased ones with the covering removed: http://www.ebay.co.uk/itm/05176-5x-P...item3f3df33222

Re: Making a B114 battery.
The CPC catalogue has quite a few clips and enclosures for various batteries, also springs to replace those corroded by battery chemicals. Page 1737 to page1740. A fascinating part of a very interesting catalogue.

Re: Making a B114 battery.
I bought some PCB mount PP3 clips from RS a while ago. I re-engineered them to serve as cross connect bars for linking PP3s up for a 90V battery. It worked quite well but I put a little heat shrink sleeve on each one as I was concerned about them shorting out as they were just bare metal.

B114 battery for 1940's marconiphone P20B
Hi all, this is my first post. I have acquired this lovely radio and would like to get a battery built. I've seen a previous thread about this which is now closed. Can anyone help? I live in Hove, E Sussex and would be happy to travel and of course pay for the replacement battery to be built. It may be of course that the radio needs more than just a battery...
Appreciate any advice. Many thanks, Alan |

Re: Making a B114 battery.
Usable PP3 clips can be extracted from dead PP3s. They may need a bit of fettling with pointy nosed pliers every so often to continue to grip well.
Otherwise Amazon, Ebay, just about any component distributor......

Re: Making a B114 battery.
But do you need them? If you connect one battery to the next and solder one of the common PP3 connectors with the plastic cover and tails to the end ones, with a fuse in line, job done.

Re: Making a B114 battery.
It's better to open up the PP3s and lengthen the piles.
Each PP3 contains six layer-cells. Add four more, tying the pack with waxed string, for a battery of 15 volts. Six piles of ten cells fits easily into the original size case, to give 90 volts. |
