Rechargeable Batteries: Lights use a lithium-ion rechargeable coin-cell battery (LIR2450). This battery can sustain approximately 500 recharge cycles. We designed them to need recharging about once a week with consistent commuter use—which means that the battery should theoretically last almost 10 years! The battery life can be extended by using the flashing modes more often than solid-light modes.
