If both batteries were new, the 42wh battery would last about 75% as long as the 56wh battery.

If the 56wh battery was new and lasted 100 min, the 42wh would last 75 min.

Since the existing 56wh battery is OLD, they might last about the same or the new battery might last a little longer.

Hope that helps.
