Congrats on your CJ750 combo which appears similar to mine.
My current battery is a wet-cell (acid) Yucel 12v 17Ah (C20), which is nothing special just a bog standard wet cell from ebay,
Its fitted in the sidecar boot and does its job really well and never had a problem with it going flat - even after a week of stop / start use at W&P shows.
However, I like to use the manual kick start as it feels abit more period and only use the electric start if I accidentally stall and need to make a quick get away...
Agree with Graham, Old Timer in Poland is a great supplier and very helpful.
Also try Ben at Sidecarpro who specialises in Chang Jiangs and is also very helpful - bought loads from him:
