- KYOCERA describes the cells as a semi-solid clay-type lithium-ion battery, with the electrolyte kneaded into the electrodes in advance; its 2024 release calls this cell type a world first, based on the company's own March 2021 survey.
- KYOCERA announced sales from spring 2024, and the product page still lists suggested retail prices for all three model codes with no discontinuation notice.

- It cannot be scored yet because KYOCERA's published pages and spec sheet do not print a round-trip efficiency, an IP rating or a certification listing.
- The 20,000-cycle figure (about 60 per cent capacity remaining) is a maker estimate that depends on conditions, not a warranted value; the printed warranty is 15 years on equipment and capacity and 10 years for natural disaster cover.
- The page also shows Enerezza PlusⅡ as a related product; this record covers only the three codes above and is not joined to it.
