FAQs about the e-bike replacement battery

Can I continue to use my original Yamaha charger?

Yes, this replacement battery is fully compatible with the original Yamaha charger for the 36V system. Please note that, due to the very high capacity, the charging time is correspondingly longer than with a battery of lower capacity.

How far can I get with this 20.7Ah battery?

The range depends on many factors, such as the selected support level, the terrain, rider weight and tyre pressure. Compared to the original batteries with 400Wh (approx. 11Ah) or 500Wh (approx. 13.8Ah), however, you will achieve a significantly higher range of up to 50% and more with this 745Wh battery.

What are the advantages of Li-Ion technology compared to older batteries?

Modern lithium-ion technology provides higher energy density, which means more energy can be stored in a lighter, more compact housing. In addition, it does not suffer from a memory effect, so it can be recharged flexibly at any time, and has very low self-discharge when not in use.

How should I store the battery in winter?

Store the battery in a cool (10-15°C), dry place and avoid frost. The ideal state of charge for longer storage is about 30% to 60%. It is advisable to check the state of charge every 2-3 months and briefly recharge the battery if necessary to avoid deep discharge.
