1, if usually open very little, did not open until a week long trip continued mileage of 60% -70%, we recommend charging once.
2, if not open out or long-term, we recommend charging 3 wheel electric bicycles once a month.
3, in any case, not more than eight hours charging time, especially 3,4 points mentioned case, not more than five hours.
4, use a new three wheel bicycles battery in 8-12 months to go to the repair shop for a water and pulse except vulcanization.
The above cases are no significant drop in battery performance on the premise that if the battery performance has decreased significantly, modify discretion.
