1.2 Impact of Lithium Technology
Lithium battery packs play a central role in enabling Lightweight Trends. You benefit from their high energy density, which means more power in a smaller, lighter package. For example, a typical lithium-ion cell offers a platform voltage of 3.7V and an energy density of 150–250 Wh/kg. This outperforms legacy chemistries like nickel-metal hydride (NiMH) or alkaline batteries, which deliver lower energy density and require larger, heavier packs for the same runtime.
Battery Chemistry | Platform Voltage | Energy Density (Wh/kg) | Typical Cycle Life |
|---|---|---|---|
Lithium-ion | 3.6-3.7V | 150–250 | 500–1,000 |
NiMH | 1.2V | 60–120 | 300–500 |
Alkaline | 1.5V | 80–100 | Single-use |
You gain longer operational time and faster charging with lithium battery packs. This technology supports the Lightweight Trends that define modern handheld testers, making your equipment more competitive and reliable in the field.
