 We recommend to replace the battery pack after 1 year you purchased. 

 Normally the Li-ion battery life cycle would be 500 times when charging&discharging. mBP-d2s has 2 x Li-ion battery installed, so mBPS-d2s’s battery life cycle

would be 1000 times, but the battery life cycle is very differ from how many hours a user uses a day or environment&humidity.If the user uses the mBPS-d2s for 4-6 hours a day, the user can use the mBPS-d2s at least 1-2 year without replacing the batteries.

 The battery’s capacity is getting smaller depending on use, so if you think the mBPS-d2s’s batteries works good after 1 year you purchased, you don’t need to replace the batteries.


 When you don’t use the unit, please power off the unit and also the charger to prolong the battery’s life cycle.

mBPs-d2s houses 2 batteries, each battery will take around 3 hours to charge, so total 6 hours will be taken to charge fully.
