Questions about this item

When should I expect the 4078 mAh capacity to need replacement?

The 3-cell lithium-ion pack will gradually lose capacity; plan a replacement once run-time becomes too short for daily use.

What limits the 46.5 Whr battery first during sustained use?

The 4078 mAh capacity sets the run-time ceiling, so heavy workloads drain the 11.4 V pack fastest.

How much heat does the 11.4 V pack generate when running all day?

Normal operation produces only modest warmth; the built-in circuit protection keeps current stable and prevents excess heat.
