PowerWarehouse TN70C laptop battery 15.2V 4000mAh for Dell Inspiron 13 14 16

Replacement Battery for Dell Inspiron 13, 14 and 16

This new PowerWarehouse TN70C battery fits a wide range of Dell Inspiron models across 13, 14 and 16 inch sizes. It replaces OEM part numbers TN70C, N9XX1 and JGCCT. The unit is designed for owners of compatible Inspiron 5310, 5320, 5330, 5420, 5425, 5430, 5440, 7420, 7430, 7440, 5620, 5630, 5640, 5645, 7620, 7630 and 7640 laptops, including 2-in-1 variants. It is not suitable for users whose Dell laptop requires a different voltage or connector layout.

Capacity and Runtime Headroom

The battery delivers 15.2V and 4000mAh, matching the original specification for the listed models. It provides a direct capacity match for daily workloads such as document editing, web browsing and video playback. Runtime will decrease under sustained high-load tasks like rendering or gaming, where the fixed 4000mAh capacity reaches its limit faster than higher-capacity alternatives. Buyers needing extended off-grid operation beyond a single charge cycle should note the capacity ceiling.

Thermals, Noise and Power Draw

As a passive component with no moving parts, the battery produces no audible noise during operation. Normal discharge generates modest warmth consistent with lithium-ion chemistry under typical office loads. The pack draws power only when the laptop is unplugged, imposing no additional drain on the AC adapter while connected. Excessive heat may appear only if the host system's cooling is already compromised or during continuous maximum processor utilisation.
