140mAhg

140mAhg refers to a battery capacity specification commonly used in small electronic devices, particularly those powered by coin-cell batteries. The term combines two units of measurement: milliampere-hours (mAh) and grams (g), indicating both the battery’s capacity and approximate weight. In this context, "140mAhg" suggests a battery that delivers 140 milliampere-hours of charge while weighing around one gram, though the exact weight may vary slightly depending on the battery type and manufacturer.

Such batteries are often found in low-power devices like remote controls, small sensors, medical patches, or wearable electronics. They are typically rechargeable or disposable lithium or alkaline cells, designed for compact applications where space and weight are critical. The "mAhg" notation helps users quickly assess a battery’s efficiency, as a higher mAh-to-gram ratio generally indicates better energy density.

The term is not standardized and may be used informally by manufacturers or enthusiasts to describe battery performance. For precise specifications, users should refer to the battery’s datasheet, which provides details on voltage, capacity, and physical dimensions. While 140mAhg batteries are common in niche applications, their use is less frequent in mainstream consumer electronics, where larger capacities (e.g., 300mAh or higher) are more typical.
