Frequently Asked Questions
- Q: What steps should I take if my battery does not fully charge frequently?
- A: It seems like there is a possibility that you are engaging the battery in rigorous load without riding the motorcycle for a long time.
- Q: For how long after ceasing to use the motorcycle should I charge the battery?
- A: Charge it at an interval of 14 days as this interval minimizes the chances for sulfation deposits to be developed.
- Q: Which symptoms will describe performance of regulator/rectifier the best?
- A: Overcharging the battery or inadequate charging are certain aspects that can help identify the problem.
- Q: Am I allowed to open the cap on a maintenance-free battery?
- A: Opening the cap might compromise the integrity of the battery, so it should not be done.
