Battery life
- In laboratory conditions over 250 simulated golf cycles, the battery can be expected to lose 15% capacity
- The battery can be expect to lose 2-3% capacity per year through cell degradation, compared with a lead/acid battery which can lose 8-9% per year
- During testing of the battery with the Stewart Golf Q-Series , its average use was 12-15Ah of the 20Ah battery per round of golf
