Direct replacement battery

This lithium-ion cell restores power to compatible HP Slatebook 10 and Pavilion 11-h100 series devices. It matches the original 7.4V 21Wh specification and replaces part numbers including MY02XL, HSTNN-LB5C and 21CP3/97/91. The black pack arrives new and carries a 12-month warranty. Buyers with laptops outside the listed model range will not find a guaranteed fit.

Installation fit and clearance

The battery slots into the existing bay without adapters or cable changes, freeing the user from a tethered power brick. No BIOS update or driver install is required; the system recognises the cell on first boot. Machines that use a different voltage or connector layout cannot accept this unit.

Sustained discharge behaviour

Under continuous load the 21Wh capacity delivers a steady 7.4V output until the protection circuit triggers a safe shutdown. The lithium-ion chemistry maintains stable voltage through the discharge curve rather than sagging early. Heavy workloads that exceed the cell's rated capacity will see reduced runtime compared with lighter use.

Questions about this item

How long will the 21Wh battery last before the voltage drops under a full-day workload?

The 21Wh lithium-ion cell delivers 7.4V and 21Wh of capacity; actual runtime depends on the laptop's power draw, so heavy use will deplete it faster than light tasks.

Does the battery generate noticeable heat or fan noise when the laptop runs all day?

The battery itself has no moving parts and produces no fan noise; it may warm slightly during continuous discharge, which is normal for a 7.4V lithium-ion pack.

What must already be in the laptop for this MY02XL battery to work?

Your laptop must be one of the listed models such as Pavilion 11-h100 or Slatebook 10-h000sa and use an original part number like HSTNN-LB5C or 21CP3/97/91 for the battery to fit and connect correctly.
