Size, terminals and hold-down of the Motobatt YTX20BS

What the Motobatt YTX20BS is for
Designed for motorcycles, scooters, quads and personal watercraft, the Motobatt YTX20BS replaces the original battery of bikes that use this code or format. Check the position of the positive terminal before ordering. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 6.50 kg.
The Motobatt YTX20BS: Quadflex range and AGM technology
The YTX20BS is part of the Motobatt Quadflex range. Choosing the right reference within the series comes down to capacity, dimensions and terminals: technology and quality are common to the whole family.
AGM (Absorbent Glass Mat) technology seals the electrolyte in glass microfibre. The result is a maintenance-free battery that is highly vibration-resistant and able to withstand deep discharges that would ruin a classic lead-acid battery.
Motobatt: the maker behind the YTX20BS
Motobatt is the motorcycle battery specialist with Quadflex technology: four terminals that let you connect the battery in any position and a sealed AGM construction ready to fit. We guarantee that every Motobatt arrives new, charged and with the manufacturer's full warranty.
Manufacturer's warranty
The Motobatt YTX20BS comes with the manufacturer's official warranty. The warranty does not cover discharge through prolonged inactivity: if the bike stands for months, use a trickle charger.
How to make it last longer
Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators. If the bike spends the winter standing, connect a trickle charger: deep discharge through inactivity is the first cause of premature failure.

Orders placed before 6:00 pm with the battery in stock ship the same day.

Frequently asked questions
How should this motorcycle battery be charged?
With a 12 V motorcycle charger delivering at most 10 % of its capacity: 2.1 A for its 21 Ah. High-current car chargers can damage it. If the bike is laid up for the winter, keep it on a maintenance charger.
How long does the Motobatt YB16CLB battery last?
There is no exact figure: for a battery such as the Motobatt YB16CLB, a reasonable guide is 3 to 5 years, keeping it charged when the bike is not in use. Many factors play a part: how it is used (lots of short trips, for example), temperature (cold makes every start harder and intense heat evaporates the electrolyte), the condition of the alternator and charging system, power drawn with the engine off and maintenance.
What are the dimensions of the Motobatt YB16CLB battery?
Before buying, measure the space in your motorcycle: one extra millimetre can stop the hold-down clamp from closing. The Motobatt YB16CLB takes up 175×87×155 mm (length, width and height, terminals included).
