Customer Questions & Answers
What type of maintenance does the YTX20L-BS battery require to extend its service life and ensure optimum performance?
The YTX20L-BS is a sealed battery (maintenance-free); it only requires external checks of terminal and connection cleanliness, avoiding sulphation. It is recommended to charge it periodically if the motorbike is not used for more than 1-2 months and to avoid deep discharges, as these significantly affect its service life.
What are the exact voltage and nominal capacity values of the YTX20L-BS, and what operating limitations does it have in extreme temperatures?
The nominal voltage is 12 V and the capacity is 18 Ah. Performance may be reduced at temperatures below -15 °C or above 50 °C: in extreme cold, starting capacity decreases (around 30% less at -18 °C), while high temperatures can shorten the life of the battery.
If replacing it, what technical aspects should the user check to ensure the YTX20L-BS is compatible with their vehicle?
The user should check that the dimensions (175 x 87 x 155 mm), terminal polarity (positive on the right), voltage (12 V) and capacity (18 Ah) match the motorbike or quad manufacturer’s specification. They should also verify that the terminal type is compatible with the vehicle’s cables.
What safety certifications or standards does the YTX20L-BS battery comply with, and how does it compare in this respect with conventional acid alternatives?
The YTX20L-BS complies with international standards for sealed lead-acid batteries, such as European standard EN 50342. Unlike conventional open batteries, the YTX20L-BS, being sealed and maintenance-free, minimises the risk of leaks and gas emissions, improving safety during use and handling.
Which motorcycles is the YTX20L-BS Motorcycle Battery compatible with?
