⋅

hr; car batteries have

much higher capacities. The basic formula for battery life is:

Runtime (hr) = Battery capacity (A

⋅

hr) / Current load (A)

Battery life and performance depend on various factors including battery type, condition, charge

critical.

Three System Examples

Reference Note:

Although the preceding three examples make use of one or more TR-40U power adapters,
