Yuasa Battery Yumicron YB4L-B (also as replacement for 12N4L-B)

The Yumicron 12 Volt Starter Battery for higher demands on motorcycles, scooters, quad bikes, snowmobiles, ride mowers etc.


  • Lead accumulators of the highest quality from the original equipment manufacturer of many brands
  • Robust glass mat can withstand vibrations
  • The extra-thin separators allow the installation of additional plates and provides up to 30% more starting power than conventional battery types
  • Cell connectors that run through the wall minimize the internal resistance, which results in maximum performance
  • The Sulphate Stop insulates plate sulphation and prolongs its service life
  • Each battery is thoroughly tested and checked before delivery
  • Is delivered dry - please also order the appropriate battery acid (50020000010) for the filling (approx. filling quantity up to the maximum marking, see article description)
  • WARNING: Use acid only during initial filling - should the liquid level have dropped during use, only fill with distilled water (50020000250)
  • Is delivered complete with venting hose and connecting bolts


  • Please check in advance that it is suitable for your vehicle (fitting accuracy, dimensions, type, position of poles and venting), as it is not possible to exchange a filled battery
  • Before filling the battery, remove the filling plug and the venting cap
  • Add acid and allow to stand for about 30 minutes, so that the air can easily escape - then check the acid level and top up if necessary
  • Insert the plug for the filling openings, connect the breather hose, install the battery and start it - the battery does not yet have the full power (about 70%), but it can be used for starting several times without problems
  • The battery reaches its full performance on the first trip or before using a battery charger

Gutes Preis/Leistungsverhältnis

Review by Mikesch
Ich hatte die Yuasa-YB4L-B genau 32 Monate in meinem Yamaha Neo-2T-Roller ohne Probleme das ganze Jahr durchgefahren und nie Startschwierigkeiten. Jetzt im März 2016 schwächelte die Batterie und ich musste vor der Fahrt den Kickstarter benutzen, nach weiteren 5-6 Wochen Standzeit war der Roller nicht mehr anzubekommen. Ich baute die Batterie aus, füllte die Batterie auf Max. auf und hängte sie an ein Motorradladegerät. Nach ca. 3 Stunden zeigte sie mir volle Ladung an. Ich baute sie ordnungsgemäß in meinen Roller ein und beim ersten Startversuch sprang der Roller sofort an. Vielleicht kann ich sie jetzt noch einige Sommermonate fahren, vor dem Winter bau ich sicherheitshalber eine neue ein. (Posted on 5/11/2016)

Bewertung: Yuasa 12V 4,0 AH Batterie - OK!

Review by Matze
Diese Batterie war beim Kauf in meinem Yamaha Neo´s 50 2T Roller verbaut und hat gute 2,5 Jahre zuverlässig mit dem Elektroschalter ihre Dienste getan. Der Roller wurde das ganze Jahr gefahren und stand Sommer wie Winter nur in einem Holzschuppen, daher finde ich Preis / Leistung ganz OK! Auffüllen von destillierten Wasser auf die Markierung Max. sowie einen Nachladeversuch fand erst nach den 2,5 Jahren statt. (Posted on 5/5/2016)
