Ranked on manufacturer-stated cycle life. Counts are only comparable when discharge rate, temperature and end-of-life threshold match — the conditions behind each figure are shown under the number. Figures marked not like-for-like were measured under different conditions and should not be read against the others without confirmation from the supplier.
Each cell is checked against the project specification. A cell is PASS only when it meets every requirement, PARTIAL when some are met, and FAIL when none are. A dash means the supplier has not stated that figure yet.
Engagement status with each supplier, split by Legal, Commercial and Technical. Commercial shows the quoted cell price where received; Technical shows whether datasheets are in hand. A dash means nothing recorded yet.
