I got the handlamp, but I don’t have a clue where to get a decent battery for it!
If you are anything like me, you will appreciate that any item that qualifies as a museum piece must have all the original bits and bobs to boot.

But the chances of finding a fully – working (original) NiFe battery is getting slimmer as time marches on
For collectors trawling through the Internet to try and find a fully-working original NH10 nickel iron battery, the task is like trying to find a needle in a haystack. The reason for this is that many original pieces will be irreparable due to age.
Help is at hand
Fortunately, it is possible to opt for neat little Nickel Cadmium batteries, instead of the original Nickel iron battery.
So, you could end up enjoying a pastime of the 50’s and 60’s. Namely, shining beams of light that form concentric circles on to your dark bedrooom ceiling – what a light show!

Roel explains:
“As the battery is missing and I cannot obtain a feasible replacement I decided to go for a solution that will not compromise the original structure. I found these NiCad cells on eBay that will fit the housing without modifying anything. A 4.8 V bulb will probably also fit the lamp as you mentioned the standard bicycle bulb.”

Battery dimensions are perfect
Roel explains:
“They measure app. 100x55x16mm and a pack of four should fit in snugly. Using the screwed terminals I will be able to connect them without modifying the lamp itself.”

Roel continues:
“I connected the cells with Aluminium strips and added the terminals.
The pack fits exactly in the housing and sits tight. No rattling. It is now charging on a 4,5v 500 mA adapter. It started at app 350 mA. The lamp works, see the pictures.”
