EFB 54459 12V 44AH
JEJE POWER
85071000
The EFB 54459 is a 12V 44Ah Enhanced Flooded Battery (EFB) designed for passenger vehicles equipped with start-stop systems. Built with calcium-calcium grid technology, it withstands the frequent charge-discharge cycles that start-stop operation imposes, reducing the risk of premature capacity loss common to conventional flooded batteries in urban driving. The battery measures 206 × 174 × 189 mm and maintains cranking performance at discharge temperatures down to -20°C. With a self-discharge rate of no more than 3 percent per month at 25°C, it is suitable for auto repair networks, parts distributors, and vehicle importers that require consistent starting reliability across inventory and service intervals.
Both positive and negative grids use a lead-calcium alloy, which lowers water consumption and internal resistance compared with lead-antimony designs. The reduced internal resistance improves charge acceptance during the short recharge windows between engine restarts, helping the battery maintain state of charge in dense urban traffic.
The EFB design incorporates a reinforced plate separator and improved electrode compression to handle the deeper discharge cycles associated with start-stop operation. This construction helps preserve cranking amperage over a higher number of engine starts than a standard flooded battery in equivalent service.
At 25°C, the battery loses no more than 3 percent of its charge per month, allowing vehicles in seasonal use or dealer inventory to retain starting voltage for extended periods. The battery is rated to deliver cranking current at temperatures as low as -20°C, supporting vehicles operated in temperate and cold-climate markets.

The battery is engineered for compact and mid-size passenger cars fitted with factory start-stop technology, where the engine shuts off at traffic stops and restarts automatically. Its cycle durability supports the repeated restarts typical of city commuting.
For independent garages, franchise service centers, and parts distributors, the EFB 54459 offers a standardized replacement option for vehicles requiring an EFB-class battery. Its DIN-standard footprint and terminal configuration simplify inventory management and cross-referencing across vehicle makes.
The EFB 54459 is manufactured by Jujiang Power Group Co., Ltd. under an IATF 16949-certified quality management system (Certificate No. 0547337). The production facility also holds ISO 9001, ISO 14001, and OHSAS 18001 registrations, and the product carries SABER certification for access to the Saudi market. Each unit undergoes charge acceptance and voltage verification before shipment.
The battery fits 12V passenger vehicles equipped with start-stop systems that require an EFB-class battery with dimensions of 206 × 174 × 189 mm. Confirm the battery group size and terminal orientation in the vehicle owner's manual or with a qualified technician before installation.
EFB batteries use a reinforced separator and improved plate construction to tolerate deeper and more frequent discharge cycles than conventional flooded batteries. This makes them suitable for start-stop systems, where the battery discharges during engine-off periods and recharges while driving.
Yes. The EFB 54459 maintains performance in both urban start-stop conditions and sustained highway driving. Its low self-discharge rate and stable voltage output support consistent operation during extended trips, and the alternator recharge cycle helps maintain full state of charge.
Store unused batteries in a clean, dry, ventilated area away from direct sunlight at an ambient temperature between 10°C and 25°C. Ensure batteries are at full charge before storage, and apply a maintenance charge every 3 to 6 months to prevent deep discharge and sulfation.
