The battery unit won't be replaceable but it will take a long time before it gets to the point that it no longer holds a charge. VEIU’s battery can retain over 80% of its capacity over 300 charge-discharge cycles. Since VEIU has a low standby power consumption, there is no need to charge the battery very frequently. A fully-charged battery can last up to two months in standby mode. Therefore, the mentioned number of charge-discharge cycles is basically stretched over a long period of time.
