That is the main thing that limits their lives on Mars. Once the dust cuts off light to the solar panels they can't rechage their batteries and they die. The number of times the batteries can be recharged before they start failing is the other major limiting factor to their lives. That fact that they've lasted more than four times their initially predicted lives is amazing.
