S1--How much does it cost to replace the battery outside the warranty period?

We've conducted thorough tests for battery durability during the design and production phases. Our batteries are designed to maintain over 85% capacity after a full 1000 charge-discharge cycle, so you don't need to worry about battery replacement. Therefore, we are sorry that the price for battery replacements in our after-sales service has not been set yet. We apologize for any inconvenience this may cause you.
