Personally I am looking for lower cost batteries (that are at least UL 1973 Certified) I can get to be approved in a municipally regulated solar install & that would arguably be covered by my home insurance...
In looking through various threads I wasn't able to find a listing of at least UL 1973 Certified batteries in a concise spreadsheet which ideally gives an indication of price per unit/etc.
The following is the spreadsheet I started that I am sharing here to help others:
https://docs.google.com/spreadsheets/d/1vkRfsckYZs0M5bKzcd395HA2cmzJrUs9DSDYGuabSiY/edit?usp=sharing
Please let me know if there are any other cost-effective UL Certified Batteries to add... I also welcome input on columns to add to this spreadsheet (or other changes) to make it more helpful. Feel free to add comments to the sheet or copy it to your drive and edit to your content (add columns/reformat/etc) and send me the link and I will do my best to update my original (I purposefully left it unprotected so folk could make copies of it & use it as desired).
Note that multiple other threads seemed to asking for the same info I was looking for but no actual answers... In my research the best thread I found so far was this thread:
diysolarforum.com
While that thread didn't have what I was looking for it did get to this California State site that list equipment, including batteries, that are UL 1973 Certified & approved for use in California:
www.energy.ca.gov
Note that from the California site I got the initial source for my spreadsheet and then I started adding columns that I was looking for and then rows/entries for batteries that were not on the California list but are UL 1973 Certified... Currently California is only tracking UL 1973 on it's list of approved Batteries for Solar... If you click on 'Download Excel file' they have 3 columns tracking UL 1973 but nothing on UL 9540 (at least yet) and I will try to check back periodically to see if it is added. The downloaded spreadsheet does mention 'Certified JA12' which I think points to 'Appendix JA12 – Qualification Requirements for Battery Storage System' which does say "the battery storage system shall be tested in accordance with the applicable requirements given in UL1973 and UL9540" but every column tracking JA12 says "No Information Submitted" on every row so it looks like they haven't gotten this tracked/implemented yet...
Note also that any price listed may not be the lowest price available at any given time as I only put what I saw as the lowest at the time I did my update for that row. In most cases I stopped after 5 prices and took the lowest if the vendor site seemed at all decent and possibly reputable (and in some cases I could only find 1 price or no prices). My focus was on smaller, preferably modular batteries, that can be stacked in solar setups (like by a DIYer).
Note also that I do not vouch for any vendor listed in here and the links are just for price range reference... If you do find better prices and or strong vendors that you can vouch for please post them to the thread and I will try to update the relevant row...

Any UL listed solar components pls submit?
I've come to realize ppl just don't know about solar electrical components having UL stamp or not. Stamp is only absolute proof. That was in a USA Today article about UL stamp becoming #1 Customs electronics fraud issue. I'm beyond annoyed my NC county ordinance requires all solar electrical...
