    Posted: 05 June 2023 at 21:29
I have a Minolta External Battery Pack Holder BH-100 that holds a couple of Minolta NP-100 lithium ion batteries .
It can be used with the Minolta DiMage series of bridge cameras rather than using the four AA batteries in them .

There due for renewal but I'm struggling to find some .
I think the original ones were made by Sony and were used by several camera manufacturers but sold as different designations .
Same as the NP-400 was also used in Pentax and Samsung DSLRs ( the Pentax K10d and 20d , and Samsung rebadged ones the GX10 and 20 )

So does anyone know what else these batteries were known as ?

Here's a couple of pictures of them to jog your memories .

I have bought the NP-400 and charger for my 7D directly from Pantona, a German Company. Still great colors of the 7D ;-)
But the does not have the NP-100 available...

I have made some search a found one at a German Photo Shop: https://www.foto-sandor.de/original-minolta-np-100-lithium-ion-battery-pack/foto-zubehoer/akkus-ladegeraete_57102_72007
Photo Sandor is a good reputated German foto equipment dealer. I have also bought several used from them. The ship also to UK.

Since the NP-100 basically is extinct, a more viable long term approach would be to make an adapter. This may not be so difficult because of the NP-100 length (quite a bit longer than most nominal 7.4V Li Ion batteries, giving room for an adapter).

Addy, look at the serial number 2A13.

Thank's for the link .
I think it's the same firm I found listing one on ebay . Under the details , their down as being used rather than new .
Being the best part of twenty years old , I'd rather have a new , third party set .

I can't remember where I put mine as I've not used them for a while , so I did a Google search for batteries to find suitable replacements .
These shots are just some random ones that came back off Google images , that it must have got off either their website or ebay listing .

I've just included them on here so people can see what they look like in case they recognise them as being the same as another type .

I was hoping someone would recognise the terminal layout of them being on another type of battery .
If so they could be put in place and the rest of the battery chamber could just have a piece of foam to hold it in place .

Ah, that explains the pictures
I feel the problem is that these were only for the batterypack - I doubt they sold many and I doubt there was a large 3rd party market back in the day - let alone now. I can find Minolta NP-200, 400, 500, 600, 700 and 900 - but no NP-100.

Sorry

I'd open them up and see what cells they have and replace the cells.

It a very helpful link to have , I didn't know about that firm .
Unfortunately they don't seem to have this battery as it wasn't used inside a Minolta camera , just a separate battery holder .

Minolta seemed to obtain batteries for their cameras that were also used in other brands gear .
I was hoping that this was the case here .

It might be , but it would be a case of getting lucky and someone recognising it as being the same as the battery of a camera they once owned .

That would be a simple solution if you have the skills for soldering onto battery terminals .
I'm not convinced I have !

But as an alternative I'm thinking of buying a battery charger and salvaging the contacts out of it to convert the battery pack to use the same batteries as my A mount gear .
    eBay twin battery charger

Soldering the back of the chargers terminals to the holders terminals should be easy .
As long as there is enough space for the Sony batteries , it should be fine .
I think the battery compartment will fit them .
I need to dig it out to check first .

Another thought is just using some brass tube of the correct dimensions to slot in the Sony battery and bend down below it to connect onto the Minolta terminals .it depend on the space in the battery compartment.

That would be an easy solution as it's just a bit of cutting with a Dremel and bending
They can be held in place with an elastic band and a lump of foam .
