Dell BTRY PRI 64WHR 4C LITH SWD - accu - 4000 mAh (3RR09)

The Dell BTRY PRI 64WHR 4C LITH SWD battery stands out with its 64 Wh energy reserve and 4-cell lithium-ion construction, giving compatible Dell Latitude and Precision laptops a dependable internal power source. It is built as a direct replacement for systems that use the 3RR09 part number, so the fit and electrical behaviour match the original specification.

Highlights

• 64 Wh capacity supports extended work sessions away from mains power
• 4-cell lithium-ion design balances weight and runtime
• 4000 mAh charge capacity at 15.2 V
• Internal form factor for a clean, integrated installation

In daily use

This battery is intended for users who need a fresh power pack for their Dell Latitude 5000 Series or Precision 3000 Series laptop. The 64 Wh rating means it can hold more energy than many standard 40–50 Wh packs, which translates into longer periods between charges. Because it is an internal battery, installation is typically done with the bottom cover removed, and it is not meant to be swapped on the fly.
