Battery Technology Inc. 451-BBSY-BTI 4 Cell 7105 mAh 7.6V laptop battery for Dell E7270 E7470

Direct replacement for Dell E7270 and E7470

This 4-cell lithium-polymer battery is built to fit Dell Latitude E7270 and E7470 notebooks. It arrives new and ready to install without adapters or modifications. The black casing matches the original chassis colour. Buyers with other Dell models or non-Dell laptops cannot use this pack.

7105 mAh at 7.6 V for typical office workloads

The 7105 mAh capacity delivers several hours of document editing, web browsing and video playback on a full charge. Runtime shortens under heavy CPU loads, discrete graphics use or high screen brightness. Cells will degrade over time, so maximum runtime decreases after repeated cycles. Users needing all-day power without recharging should consider a higher-capacity alternative.

4-cell lithium-polymer chemistry at 7.6 V

The pack uses four lithium-polymer cells wired for a nominal 7.6 V output. This voltage must match the laptop's charging circuit exactly; mismatched voltage can prevent charging or damage the system. The 4-cell layout keeps the battery slim for the E7270 and E7470 chassis. Systems expecting a different cell count or voltage will not recognise this battery.
