How do I make my e-bike battery last longer?

Store between 20-80% charge for daily use, avoid full discharges and storing at 100%. Keep the battery at room temperature — extreme cold reduces capacity by up to 30%. Charge after rides rather than before (lithium cells prefer shallow discharge cycles). Most batteries are rated for 500-1000 full charge cycles, translating to 3-5 years of typical commuter use.
