Total Micro 33YDH-TM 56 Wh Li-ion Battery

Maintain mobility without compromising uptime. This Total Micro 4-cell lithium-ion battery delivers 56 Wh of capacity at 15.2 V, giving compatible Dell laptops the power reserve needed for field work, travel, and long sessions away from the dock. It is designed to meet or exceed OEM specifications, so procurement teams can replace aging batteries without changing the user experience or introducing unnecessary risk.

A well-matched replacement helps preserve runtime expectations, reduces unplanned interruptions, and supports a cleaner refresh strategy across mixed deployment cycles. The 4-cell design keeps the footprint practical for everyday carry while still providing the energy density needed for business workloads. Choose this battery when you need a replacement that aligns with enterprise support expectations rather than a generic aftermarket part. It is a straightforward fit for keeping laptops in service longer, protecting productivity, and avoiding premature device replacement.
