Questions about this item

Which capacity version of this NShi battery should I pick for my Dell Latitude E5450?

The NShi replacement is offered in a single 62Wh capacity at 7.6V, matching the original Dell R0TMP, FDX8T and WTG3T part numbers for the E5450, E5550 and E5570 series.

What does the 7.6V 62Wh rating mean for daily run-time on my E5550?

At 7.6 volts and 62 watt-hours the pack stores roughly the same energy as the factory battery, so typical office workloads should deliver comparable hours per charge once the new cell is calibrated.

Does this battery use the same connector and charging protocol as the original Dell pack?

Yes — it is built to the Dell R0TMP, FDX8T and WTG3T specifications, so the physical connector, pin-out and charge negotiation work directly with the Latitude E5450, E5550 and E5570 charging circuit.
