How many times can the Eco-Drive system in Citizen Mission Antarctica be recharged? Does the rechargable battery have a limitted life span? Can the battery be charged only a limited number of times? Will partial charging ruin the battery life?
The manganese titanium lithuim ion rechargeable battery used in the Eco Drive watches have a life of about 40 years. Even after 20 years, they will maintain 80% of their capacity.
They are not affected by partial discharge and charge. They have a duty rate of 500 complete charges (completely depleted to full charge) so there is no need for worry at all about the life of the battery.
