Can anyone tell me the best way to treat NiMH batteries? To get the maximum life, should they be recharged only when fully discharged or is it OK to top up each day? My new battery lasts me 2 days commute (30 miles) if I put in a reasonable effort myself and do not have strong winds. Should I recharge every 2 days or after each day? I have read conflicting reports about this on the web.
