I have a 2010 Kalkhoff pro connect sport, which I have used a great deal. The battery has lasted a lot longer than I had expected but is now starting to fail. The bike has a 250w Panasonic center drive motor that runs at ~26 volts. Replacement batteries used to be readily available but I am not having much luck finding one quickly. Also, I know that the batteries were upgraded in terms of capacity but I don't really need that capacity for my daily commute. Given the age of the bike I am a reluctant to spend the roughly $800 that the high-capacity batteries were selling for in the past. I'd appreciate suggestions about where I could get a suitable battery or whether the current battery could be re-celled.
Need replacement battery for Kalkhoff Pro Connect

There's a shop in Las Vegas, and a fellow on Facebook in the endless sphere group that does repairs. I spent a few minutes trying to find information on their batteries, but there's not a lot out there. My biggest worry would be having a proprietary communication system that needs to be in place to "talk" to the controller. I can't find that answer either. Spend sometime researching and reading forums to gather as much info as you can and I'll happily help you find a solution, or repair person.

EDIT after being frustrated at the lack of information I gave it one more try. There are alternatives. AND you could save a lot of $$ by using an alternative battery. BUT it CAN be re-celled. You may have to subscribe.

Read to post #16 in this thread. A 24V battery and some simple soldering or wire crimping will work!

Thanks very much. I'd like to try an alternative battery given the age of the bike. Within a couple of years I'm likely to get a new bike but the available options seem to keep on getting better and other than the battery issue my Kalkhoff serves my needs.
Amazon lists a number of relatively cheap 24v ebike batteries and I see that the second pedelecs entry that you copied gives the necessary information on electrical connections. I am pretty sure that I can figure out a way to mount the battery on the bike but I am concerned about waterproofing and making connections that won't shake loose. Is there any way that a pre-made battery back (one that doesn't require that I do spot welding between cells) might fit inside the case for the current battery? For example, this web site lists what they call "naked" battery backs like this one here (https://ebikemarketplace.com/collections/lithium-batteries).
In terms of having the current pack re-celled, the forum entries on this site made the process seem time consuming, a bit uncertain and likely close to as expensive as a new battery pack if I could find one. I'm not sure if that is an accurate evaluation on my part.
Thanks again.

You may be able to find a pack to fit but I'm afraid there might be some pitfalls and problems that would arise. You could use a soft pack battery in a nylon case in place, but I'd consider going the rebuild route. It's really not a very big pack maybe 7S/3-4P 21-28 cells. And with newer 3000-3500maH cells you'd gain aH and range. Careful if you decide to buy a soft pack and adapt. Make sure the reseller has been checked out. I can reference one to be trusted, but again, Call Hi C first!

There is a bit more information from flecc at the link below:
http://www.flecc.uk/p/li_battery.html#bookmark8
It covers the kind of battery that I have now, but it doesn't say much about repair or alternatives.

That is a higher capacity version of the battery that I have now. I'd need to make sure that it fits the bike and I have seen some sites that discuss the issue. Shipping to the US may be tricky, since I expect that they would not want to send it by plane.
I will also give the Hi C battery folks a call on Monday to hear what they have to say.

Fit, since the battery listed is double sized, and I've never found a UK seller to ship to the USA.
