I had a similar situation with my late grandfathers Hacker Sovereign which I had serviced. The PP 9s were replaced with modern AA adapters but didn't look right,I had 2 original P P 9s that I took the cells out of and put the adapters in. Not only did it hold the packs in place it also looked period correct.My grandfather always scratched the date on the batteries when they were changed .It's now running with "PP9's"scratched with the date 9/12 / 69 a nice link back to my Grandfather.

With normal zinc batteries, apparently you can recharge them, but very slowly. Maplin used to sell chargers to charge normal batteries about 25 years ago. You could recharging a pp7 using a bespoke charging circuit?? I recently bought a USSR Selina radio. Excellent sound on it, and it has a turret tuner apparently. Thank you for your video.

@Radiocruncher: Energizer do PP3's in lithium but only have about 750mah so not much more then alkaline but unfortunately at £8-10 per battery wouldn't be viable. Energizer AA lithium are rated at 2900mah so 6 of them in series at 1.5v would give you a 9v option with decent current capacity or 2x 4.5v 3LR12 lantern batteries in series at around 4500-5500mah but don't think there would be space within the radio for those type.

@Radiocruncher, an excellent video, however pp3 9v batteries only have a 500-550mah capacity so you've created a battery of around 1500mah with 3x pp3's in parallel. If the 3d printed case had the space, you could build a 9v pp7 sized battery using 3v CR123A lithium batteries. A total of 9. Place the CR123A's in 3x sets of 3 in series making 9v then connect the 3x sets of 3 in parallel giving you a high capacity 9v battery of 3900mah - 4500mah. A CR123A 3v battery is rated at around 1300-1500mah. The original pp7 ranged from 2500-2700mah so you could potentially make a higher capacity lithium alternative. The smaller CR2's range from 700-850mah in capacity. Originally designed for cameras those CR2's and CR123A's became commonplace in wireless burglar alarm sensors and torches. In their early days back in the 1990s a single battery could be £7+ and that was over 20 years ago. Their far cheaper now and more readily available.

@@Radiocruncher CR123A's and CR2's are my all time favourite batteries to work with in my electronics projects. I generally use 3 of them instead of a pp3 where 9v is required. I often need 12v with low current so I use 4 of them. I'd definitely consider getting a boxful of CR123A's and experiment 😁

I did hear that they were non existent in Australia. I wonder if there are any radios about that still need them.

I do have an HMV Capri which took a 2362 which is a long narrow shape with a connector at each end similar to the PP9. It had a 8-3/PP3 clip already installed when I got it back in 1980. I believe the PP9 was a 266 in Australia. I haven't seen any Roberts or Hacker radios here although I have a Sangean DPR-34 which is the same as a Roberts Sports 2. Been enjoying the videos immensely. Marvellous! Wenlock. Almost forgot, my pride and joy is a Yaesu FRG7 which turned up at a garage sale for $50 (£25). After cleaning the band and mode switches, removing some dry leaves from the I.F. panel it works well. Cheers

Radiocruncher Granted, there are no such lithium batteries that reach 4.5 volts.

Which is the nominal charge for a pair of lithium batteries in series.

@@Radiocruncher I figured they'd use 9v batteries for that. I saw the interior of an original and it certainly looked like a whole bunch of 9v interiors all stacked on top of one another. I thought of giving it a go, but one thing I learned from experimenting with 9v batteries (or PP3s in the UK) is that I find they are the most finicky kind of battery. Other battery types like AA, AAA, C, and D cell will still work to power up their respective devices regardless if they are carbon-zinc or alkaline type batteries. But for 9V I find that there is a very, very noticeable difference between carbon-zinc and alkaline. Some amateur devices I tried to power with a carbon-zinc 9v Did exactly nothing while an alkaline worked to good effect. The only issue I would find with the 90v battery is that the connection at the top looks like a wall socket. It is a trivial task to solder (or just connect wires and secure them with electrical tape) to generate 90v, but having the final connect resemble that seems to be a challenge.

Clever solution you definitely have yourself a niche marketable item there, those PP3's are only 550mA a piece so as there is sufficient space in the casing dimensions how about AA cells for an increased margin in capacity?

Thanks Dave. 3x PP3's in parallel should give 1650mAh capacity. I will have to see if it's possible to squeeze 6x AA's in there.

A customer has suggested designing a logo with my name on so I may give that a go.
