Cold-cranking-amp verification
Every ZITEX SKU is tested to its rated CCA at -18°C per BCI standard, and to -29°C for cold-climate-positioned units. Test cells run continuously in walk-in cold chambers at our Ontario facility.
What Raya Energy actually tests, where, and how. Cold-climate qualification, cycle-life testing, plate metallurgy — the unsexy work behind a reliable battery.

Deep-cycle and dual-purpose marine SKUs run through 50% DOD cycle banks rated to 800+ cycles. Failures (defined as ≤50% original capacity) are autopsied for root-cause attribution.
Reserve capacity (the BCI-spec 25-amp constant-current test to 10.5V) measured on every production lot. Rated RC values cross-checked against measured every release.
Lead alloying choices — antimony content, calcium-tin ratio, silver and selenium additions — are tuned to the chemistry. AGM plates use a different alloy than flooded; the wrong alloy in AGM dramatically shortens cycle life.
Absorbed-glass-mat thickness, acid retention, oxygen-transport rate. The AGM separator does most of the work in a start-stop AGM battery — and most of the cost engineering happens here.
Stratification is the silent killer of flooded batteries in stop-start use. R&D characterizes when it starts, how it progresses, and what design choices (paste density, plate thickness, grid pattern) most-effectively mitigate it.
