Compatible Dell Latitude Battery

This 34GKR lithium-ion battery fits Dell Latitude 14-7000 series models including E7420, E7440 and E7450 ultrabooks. It replaces OEM part numbers such as 451-BBFT, 451-BBFV, 451-BBFY, PFXCR, G95J5 and 0909H5. The pack is new from the manufacturer and ships with two free screwdrivers for installation.

Thermals Noise and Power Draw

The 4-cell, 7.4V, 47WH design delivers standard notebook run-time without adding active cooling or fan noise. Built-in overcharge, overdischarge, over-temperature and short-circuit protection circuits manage cell stress during normal charge and discharge cycles. No moving parts mean silent operation and no extra power draw beyond the laptop's own charging logic.

Upgrade Scope and Limits

This unit restores original capacity for Latitude 7000 series owners whose factory pack has degraded below usable levels. It supports up to 500 recharge cycles over its service life. Buyers needing higher watt-hour capacity, a different voltage, or compatibility with non-Latitude chassis will not be served by this specific 34GKR form factor.

Questions about this item

How do I install the 34GKR 7.4V 47WH 4-cell battery in my Dell Latitude E7440 and what step is often missed?

Power off the laptop, disconnect the AC adapter, remove the base cover screws using the included screwdrivers, disconnect the old battery cable, connect the new 34GKR battery cable securely, replace the cover and screws, then charge to 95% before first use — many forget the initial calibration cycles.

What maintenance will the 34GKR 4-cell Li-ion battery need over its lifespan?

Perform 3 to 4 full charge cycles from 5% to 95% when new; avoid leaving it at 0% or 100% for long periods; if stored, recharge above 80% at least once a month; do not disassemble, crush, puncture, or expose to fire, water, or moisture.

What limit appears first when the 34GKR 47WH battery is used continuously under load?

The battery supports up to 500 recharge cycles over its life; sustained heavy use will reach this cycle limit before other factors, and built-in overcharge, overdischarge, over-temperature and short-circuit protection will activate if thresholds are exceeded.
