TECNIUM BT14B-4 (Manufacturer Ref: 820644) — Factory activated maintenance-free battery designed for roadsters and touring motorcycles. Pre-charged and sealed (VRLA technology), it arrives ready to use for a quick and clean replacement, without acid handling. Ideal for vigorous starts and use in cold climates thanks to its high starting current.
The radial construction and additional plates provide high power and superior longevity compared to a conventional battery (announced life cycle >3×). Maintenance-free and gas emission-free, it simplifies the maintenance of the motorcycle fleet and avoids logistical constraints related to acid transport. Easy installation to replace your worn-out battery and restore reliable starting capacity.
Examples of compatible motorcycles: YAMAHA FJR 1300 AS / FJR 1300 AS ULTIMATE EDITION (2021), HYOSUNG GV 650 AQUILA (2015) — particularly suitable for roadsters and touring motorcycles requiring a 12 Ah battery with good CCA.
