Replacement for Dell 5TF10 series

This 64Wh lithium-ion battery replaces the original Dell 5TF10, 05TF10, RY3F9, 0RY3F9, 7M0T6 and GHXKY packs. It fits Dell notebooks that require a 7.6V four-cell design and is supplied new with CE and RoHS certification. Buyers who need a different voltage or cell count cannot use this unit.

Upgrade from worn original cells

The pack restores runtime lost to aged cells that no longer hold a full charge. Swapping to a fresh 64Wh unit is worth it when the laptop shuts down early or cannot run unplugged for a useful period. Systems that require a higher watt-hour rating or a different form factor will not accept this battery.

Steady output during long sessions

Premium four-cell construction delivers stable 7.6V output across extended workloads such as document editing or media streaming. The cells resist voltage sag so the laptop maintains performance without throttling or sudden shutdown. Users who push sustained heavy loads beyond the pack's rated capacity will see reduced runtime.

Questions about this item

How do I confirm this 64 Wh battery will fit my Dell laptop?

Match the part number on your original battery to 5TF10, 05TF10, RY3F9, 0RY3F9, 7M0T6 or GHXKY and compare the physical shape to the product photos; there are two different batteries for the same laptop model and they are not interchangeable.

What is the installation procedure and the step users often miss?

Power off the laptop, disconnect the AC adapter, remove the base cover screws, unplug the old battery connector before unscrewing the battery, then connect the new 7.6 V 4-cell pack, secure it, replace the cover and reconnect AC power; the step often missed is unplugging the connector before removing the mounting screws.

When will this lithium-ion pack need replacing?

Capacity will gradually decline with each charge cycle; expect noticeable runtime loss after several hundred full cycles, at which point the battery should be replaced.
