Questions about this item

How long will the 1100 mAh 3.7 V cell last before its capacity drops off?

The lithium-ion pack is rated at 4.07 Wh and includes over-charge, over-discharge, over-voltage and short-circuit protection circuits that slow degradation during daily charge cycles.

Does the battery get hot or draw extra power when the navigator runs all day?

At 47.0 g and 5.56 mm thick, the cell fits the original cavity without added bulk; the protection board limits current spikes, keeping temperature rise minimal during continuous use.
