Questions about this item
How do I install this 4V 2000mAh Li-Ion battery in my M4 cordless tool, and what step is often missed?
Slide the battery into the tool until the latch clicks securely; the step users miss is confirming the latch is fully engaged so the pack will not disconnect under vibration.
What maintenance or replacement will this 2000mAh pack need over its life?
Expect capacity to fade after several hundred charge cycles; the 2-year warranty covers premature failure, but plan to replace the pack when run-time no longer meets your needs.
What limit appears first when I run this 4V battery continuously on high-draw M4 tools?
The 2000mAh capacity depletes quickly under heavy load, so run-time is the first limit you will hit during sustained use.
