a while ago i remember reading a thread, which i couldn't find after a search, that some people have replaced their battery with a smaller but equal powered battery made by... someone?
Anyone knows who makes this smaller sized but same powered battery that would go into my 2008 sportster 1200xlc?
I want to create room for some of the wires I have cramped up in the battery space. thanks.
Any of the lithium Ion batteries are going to be at least 1/3 the size and weigh much less with more power behind them. Check out Antigravity Batteries costs more but better and longer warranty & life span.
What size/ power battery should I be searching for ?

Shorai, Earth X, Antigravity, and Battery Tender all sell various sizes and power ratings of Lithium Iron Phosphate batteries. I have a Shorai on my 1991 that is the same stock size (exposed battery tray) but weighs 4 pounds versus almost 14 pounds for my old lead/acid. Bike instantly fires up, every time!!!! And it takes a lot of stress off my battery tray/oil tank mounts.

Find a battery site and look up the one you have now and check the specs the CCA rating is what your after. Then select a lithium brand and do the same , helps to have the size measurements off the original so you can compare to get what you are after with the extra space needed.
No affiliation and don't have one myself. But, please, Google reviews of these types of batteries. They are mixed, some have had issues, some are really happy with them.
I just purchased a small lithium battery with CCA 480 - Antigravity 16 cell AG-1601. It is L4 1/2" W3" H5 1/4" (with terminal bolts). For comparison purposes, you save about 1 1/2" in Length and about 1/2" in width versus oem size battery. It is also a lot lighter than the OEM battery. Also purchased a lithium battery charger/tender.
Buy the 16 cell Antigravity and get it from DK Customs. Their support is second to none.
I originally bought the 12 cell a while back. I had trouble with it turning over my 1200. Kevin went out of his way to make it right and eventually refunded my money after I installed a standard battery which worked.
Antigravity eventually de-rated the 12 cell to 1100cc.
Fast forward and between the standard battery getting some age and getting tired of tie-wrapping my cover shut because of relocated ECM I decided I wanted to give LiFePO4 batteries another try.
This 16 cell battery is great. There is not a hint of the starter struggling at TDC and, while a tight fit, the ECM fits inside the bracket with the battery and the cover closes and latches great.
