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.
