What this battery replaces

This 7.6 V 62 Wh lithium-ion pack replaces Dell part numbers 6MT4T 7V69Y TXF9M 0TXF9M 79VRK 07V69Y HK6DV 0HK6DV in Latitude E5450 E5470 E5550 E5570 notebooks. It is built with Grade A cells and carries CE RoHS FCC certification. The pack ships new and includes a 12 month manufacturer warranty.

Build and daily use

The black polymer casing matches the original chassis profile so the battery seats flush without forcing latches. No soldering or cable adaptation is required; the connector aligns with the motherboard header exactly as the factory unit did. A full charge cycle takes roughly 7 to 8 hours and the maker rates the cells for up to 500 recharge cycles.

When the upgrade makes sense

Owners whose original pack no longer holds a useful charge will restore factory runtime with this direct replacement. It is not suited for users who need a higher capacity than 62 Wh or a different voltage platform. The three to four initial charge discharge cycles condition the cells for maximum capacity before regular service.

Questions about this item

What voltage does the 6MT4T battery supply and how does it affect runtime?

It delivers 7.6V at 62Wh, matching the original Dell specification so the laptop’s power management sees the same voltage curve and reports capacity normally.

Will this battery fit the 15.6" Latitude E5450, E5470, E5550 and E5570 chassis without modification?

Yes, the pack is moulded to the exact dimensions of the Dell 6MT4T, 7V69Y, TXF9M and HK6DV originals and locks into the standard battery bay on all four models.

How do I install the battery and what is the step most people skip?

Slide the pack into the bay until the latch clicks, then run three to four full charge–discharge cycles of about seven to eight hours each to activate the lithium-ion cells to full capacity.
