9-Cell Extended-Runtime Upgrade

For longer unplugged runtime, upgrade to the 636631-001 9-Cell MU09 11.1V 88Wh Battery. It uses the same battery-bay latch and connector on supported MU06/MU09 systems. The additional cells cause the 9-cell pack to extend beyond the standard battery profile.

⚙️ Fit Notes

• Batteries marked 10.8V and 11.1V are alternate nominal ratings for the same three-series-cell voltage class and are interchangeable within this battery family.
• Compatible original 6-cell packs were produced in 47Wh, 55/56Wh and 62Wh versions. This item is specifically rated at 5200mAh and 56Wh.
• The 9-cell MU09 upgrade uses the same connection on supported systems but extends beyond the standard 6-cell battery profile.
