Will this battery work with my 20V Max tools?

It is listed as compatible with DCB200 series 20V Max packs, so it should fit tools and chargers that use that battery style. Check the listing's compatibility details against your exact tool model to be sure.

How long will an 8000mAh battery last?

Runtime depends on the tool and the load. Higher capacity generally gives longer use per charge than a standard 2Ah to 5Ah pack, but heavy-draw tools like saws will drain it faster than a drill.

Is a third-party replacement battery safe?

This pack lists safety protection and an LED indicator. As with any aftermarket battery, use the correct charger, avoid charging unattended, and stop using it if it gets unusually hot or swells.

Buying Tip

Before ordering, confirm your tool and charger accept the model numbers listed, and check that the pack fits snugly in the battery slot. Third-party batteries can vary in real-world capacity, so read recent customer reviews and look for a clear warranty from the seller. Also remember that higher mAh means a heavier pack, which may matter for overhead work.
