EFB battery OEM

Chengguang Power Tech manufactures EFB (enhanced flooded) batteries on an OEM basis for entry-level start-stop and higher-cycling applications.

What EFB means

EFB is an enhanced flooded battery: conventional flooded construction with improvements that raise cycling durability. It sits between standard SLI and AGM — better cycling than SLI, lower cost than AGM.

Where EFB fits

Entry-level start-stop vehicles, vehicles with moderate accessory load, and markets where AGM cost is not justified by the duty cycle.

What you define

Standard family and case (JIS, DIN/EN, BCI), capacity at C20, CCA on a named test basis, terminal type and polarity, and the label and packaging.

OEM terms

MOQ follows the container (typically one 20ft container); production lead time is 30–45 days. Manufacturing is under IATF 16949 and ISO 9001 with 100% end-of-line testing.
