On a system with multiple batteries (like thinkpads) report percentage and time remaining only for the active battery (the one being discharged). Ideally we should report all batteries, but acpi only shows time remaining for the active battery. Also callers of these functions expect a single return value. This is still better than reporting 596% remaining (like it did on my laptop). For the reference, the output of acpi command with multiple batteries looks like this: Battery 0: Unknown, 5% Battery 1: Discharging, 86%, 03:14:04 remaining
