Battery Power

The 45MG comes with three AA-size alkaline batteries.
The 45MG can also be operated using three AA-size nickel-metal hydride (NiMH)
rechargeable batteries, or three nonrechargable AA-size lithium batteries. The 45MG
does not recharge NiMH batteries. To recharge the batteries, you must use a
commercially available external battery charger (not included).

Battery Operating Time

The battery operating time depends on the type of batteries being used, the age of the
batteries, and the instrument settings. To provide realistic battery operating times, the
45MG has been tested with mid-level operating parameters (update rate set to 4 Hz
and display brightness set to 20 %).
The nominal battery operating times for new batteries are:
• Alkaline: 20–21 hours (nonrechargeable)
• NiMH: 22–23 hours (externally recharged)
