It was not that long ago that professional photographers were recommending against using rechargeable batteries in cameras. They recommended against NiCad and NiMH batteries, instead telling colleagues and amateurs to stick with single-use batteries. Things have since changed.
Lithium-ion batteries represent a dramatic improvement over NiCad and NiMH batteries. As such, they have become the battery of choice among photographers. When offered as USB rechargeable batteries, lithium-ion cells are even better. Here are five reasons they are ideal for cameras:
1. High Energy Density
Despite being rechargeable, one of the downsides of NiCad and NiMH batteries is their lower energy density compared to disposables. Photographers recommended against them because they didn’t last as long. Moreover, their discharge rate was unreliable. Disposable batteries offered a higher density and greater reliability.
Lithium-ion batteries offer a higher energy density than all three of the other formats. That is why they are lighter than …
