Bear in mind that the 300-500 cycles life span is a conservative estimate based on near 100% discharge each cycle. If don't let the battery go below about 50% each cycle then you should get 1200-1500 cycles. So let's say you're recharging twice a week at no lower than 50% DoD per cycle. At 1200 cycles that's 600 weeks or about 11 years as a rough worst case estimate.

(Kudos to John F for referencing Battery University. Good source of factual information.)
