The symptom pattern

The battery’s own indicator LEDs say it’s fully charged, but the drill itself does nothing — no lights, no trigger response, completely dead. It reads like either a failed battery cell or a dead tool, and because the battery’s charge display looks entirely normal, most people assume the tool itself must be at fault.

What’s actually happening

A battery’s charge-level LEDs are powered and read by the battery pack itself — they say nothing about whether the battery is actually making a working electrical connection with the tool it’s plugged into. On the Power X-Change platform, a battery that isn’t fully clicked into place, or one whose contacts (or the tool’s mating contacts) have picked up dust or a thin layer of corrosion, can show a perfectly healthy charge state while delivering no power to the tool at all. It’s an easy trap: the charge indicator seems to rule out the battery, so attention goes straight to the tool, when the actual issue is the connection between the two.

Working through it

Start with the simplest possible cause: pull the battery fully out and reinsert it, making sure it clicks properly into place rather than just sitting in the slot. Swap the same battery into a different Power X-Change tool if one is available — if it works there, the fault is in the first tool’s contacts or electronics, not the battery. If not, or if there’s no second tool to test with, inspect both sets of contacts closely for dirt or a dull, corroded look, and clean them with a dry cloth or a soft brush. A short rest period is also worth trying if the tool had just been worked hard. Only once seating and contact cleanliness are both ruled out does it make sense to treat this as a genuine cell or electronics failure.

Verdict

A poor seat or dirty contacts explain a large share of these “fully charged but dead” reports on this platform. Reseat and clean the contacts first — it costs nothing and resolves the fault outright far more often than it turns out to be a genuine battery or tool failure.
