Practical advice for motorcycles and quads
Adventure bikes loaded with heated grips and sat-nav ask more of the battery. Check the fuse holder near the battery when the bike seems dead. Storing a bike for winter without a maintainer often ends with a new battery.
The AGM technology explained
Picture a sponge holding the acid: that is roughly how an AGM cell works. Ambulances and police cars use AGM for their heavy electrical loads. If the original was AGM, the replacement should be AGM too.
Will the Varta YTR4A-BS fit?
- ✓ A case of 114 × 49 × 86 mm must sit flat with the clamp closed.
- ✓ Same box, opposite posts? Many sizes exist in both layouts. This one is positive on the right-hand side.
- ✓ Rated 2.3Ah: check that the charger or alternator in your system can refill a battery of that capacity in reasonable time.
