Most agree to recharge after 15 minutes of actual peddle time, recharge....Now that is actual holding the peddle down... If betting the p[aper is 30 seconds each way it will take 2 weeks to accrue 15 minutes of peddle time. Realize time spent sitting discharges batteries too. If that is all the use you get, I would recharge once a week or 10 days? A more accurate test is the voltmeter. A fully charged 36v pack will read 38.20v and a 50% discharged pack will read 36.31v. This is where it should be recharged
