The Motobatt YB16ALA2: Quadflex range and AGM technology

The Quadflex is the Motobatt range the YB16ALA2 belongs to: it shares the same construction and quality criteria with the rest of the series, and varies in capacity and format to suit each vehicle.

In an AGM battery the electrolyte is absorbed in glass-fibre separators: there is no free liquid, it cannot spill and it can be mounted at an angle. That construction lowers internal resistance, speeds up recharging and multiplies cycle life compared with a conventional battery.

Why choose Motobatt batteries

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. All the Motobatt batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty.

Warranty and coverage

The Motobatt YB16ALA2 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. Check the resting voltage before the season (above 12.6 V on a charged battery) and make sure the terminals are clean and tight.

Delivery times and returns

Order before 6:00 pm with stock available and it leaves today: mainland Spain and Portugal receive it in 1 to 2 working days, the islands and the rest of the EU in 1 to 5 days. You have 14 days to return it if it has not been installed, with free collection on the mainland, and shipment tracking by email.

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 20.5 Ah. High-current car chargers can damage it. If the bike is laid up for the winter, keep it on a maintenance charger.

How many years does this battery last?

Estimated lifespan of the Motobatt YB16ALA2: 3 to 5 years, keeping it charged when the bike is not in use. Treat it as an approximate guide, as every case is different. It can vary considerably with usage (short or long journeys), temperature, the condition of the alternator and charging system, power drawn with the engine off and maintenance. Cold demands more at every start and intense heat evaporates the electrolyte.

What size is this battery?

Check the room available in your motorcycle, because a single millimetre too much can stop the clamp from closing. Its dimensions are 207×72×164 mm, also written 207x72x164 mm; the height already includes the terminals.

Is the YB16ALA2 valid for my vehicle?

Not sure? Try your number plate in the finder (DGT/DVLA/KBA detect model and engine) or the "Compatible vehicles" tab, checked by our technical team; if your motorcycle is not there, send us make, model, engine and year on WhatsApp and we will reply during business hours (Mon–Fri 10:00–13:30 and 16:30–18:00 (Spanish time, CET)). Always cross-check with what the motorcycle manufacturer states in the owner's handbook. Our database holds 23 verified vehicle versions for the Motobatt YB16ALA2.
