Keep R10 batteries charging in a dedicated two-bay unit rather than tying up the device during a recharge cycle. The Lenovo R10 battery charger holds up to two batteries at once, helping teams maintain a practical pool of charged batteries for devices that remain in active use across a workday. The two-bay arrangement suits locations where one battery may be in use while additional batteries are being prepared for the next operator or shift. It provides a defined charging location for R10 batteries and reduces the need to handle each battery through a separate charging position. This makes the charger relevant wherever battery exchanges are part of normal R10 device operation. Lenovo part number 78818253 is the R10-specific two-bay battery charger. Match the charger to the R10 platform and the required number of simultaneous charging positions. Its distinguishing hardware characteristic is the ability to charge two compatible batteries in one charger, supporting a more orderly spare-battery routine without requiring the R10 device itself to serve as the charging location.
