Definitely not hearing aids battery. The cell is way too big to fit in a hearing aids. Also they never use NiCad in hearing aids.

Take apart any regular A...AA...AAA battery... all stacks of small batteries.

Read the battery label once open...count how many...buy them...reassemble.

Oh yeah? both hearing aids and AA, AAA are all single cell. There is no stacking.

Hi Larry,

Thanks for the reply. I was the one that very carefully removed the screws and used a little heat to "loosen" the glue to open up the case. All screws were put in a small pill container so everything is good in that respect.

Cool. I did a little searching around the FN battery pack. It is from a time when things were built more "accessably." I had to do some cutting to open my calculator batteries, so they were never quite the same afterwards.

Not sure where you have been... I loathe to post links but...and his one is 15 years old...15.

You obviously don't know about batteries. None of the ones in the video is a hearing aids battery nor AA or AAA batteries.

CAUTION CAUTION!
Conversion from NiCad to L-ion runs a significant fire 🔥 risk if the NiCad charger is still used.
Significant number of L-ion battery fires result from improper/wrong charging.

Exactly right. All that were mentioned are single cells (and they are NOT all the same type - most hearing aid batteries are air dielectric)

This Canon Ni-Cd Pack FN no longer holds a charge. The high speed one does, so the charger is still good. On the F-1 Facebook group it was suggested that Batteries Plus can rebuild it. Has anyone had this done or are there other recommendations/suggestions? I have a PhD in history which means I have no discernible skills to do this myself, probably!

Yes, Batteries Plus (at least here in Arizona) builds replacement batteries of the type you are showing. I work for a local municipality as an electrician and we replace batteries in specialty emergency lights for the water department all the time. HUNDREDS of them. The heat shrink part is really no problem and the battery techs always seem to identify just which cells were in the originals.
Still not cheap but usually 1/3 the cost of ordering from the fixture manufacturer. Only thing to make sure of is that they are able to re-connect the original wire coming out. They do not supply connectors.
Hope this helps.

A Dremel tool with a thin cutting blade opens plastic cases easily. Two caveats merged into one: Secure the battery cpack in a vise and hold the Dremel in both hands. This will help control the cutting disc so that it barley penetrates the case, and perhaps save you from a very nasty cut.

Physical assembly is one thing. Electrically balancing cell voltage and especially internal cell resistance is quite another! Unless that is done properly, a pack will not perform as expected and may fail or catch fire. NiCd is the least reliable battery chemistry and the most sensitive to imbalanced cells in a pack.

I had a Norman 400B flash about 18 years ago. The NiCd battery was a piece of junk. It failed a month after the warranty ran out.

Dear Doctor!

The company you refer to specializes in low-voltage energy storage- Batteries. If you contact them, via the link below, you can inquire about the specifications for your camera. They should be able to supply an exact replacement as per voltage, ampere/hour rating, and charger compatibility with your existing equipment.

The batteries in question are not dangerous, so if you decide on a DIY fix, you won't be electrocuted if you make a mistake. An error in polarity can possibly damage the camera and/or the charger. Acquiring batteries of the wrong specification can yied poor performance. A DIY installation may requre soldering and heat-sinking the batteries to avoid head damage during the procedure.

I have purchased parts from Battery Plus- they are completely
honest and reliable. I am a long-time electronics dabbler and have been involved in photo-electronics for many decades.

If you are not into this kind of work, it is best to have it professionally addressed.
