Wolf AGS Accu100 10.8V Replacement Battery 2000mAh

My Wolf grass shears cut fine for the first few passes then start dragging and slowing down mid-session — is that the battery dying?

That symptom — strong start, then progressive bogging under blade load — points to voltage sag under draw, which gets worse as a Li-ion cell ages and internal resistance climbs. A worn cell can show a healthy resting voltage but collapse the moment the motor pulls current through a thick grass stem. We saw this consistently on bench tests with degraded 7.2V-class packs being pushed into a 10.8V application range. Put a multimeter on the battery contacts immediately after the shears bog out: if the reading drops below 9V under load, the cell is the problem.

I charged the Wolf AGS shears overnight and by morning the blades won't move at all — fully charged but completely dead?

This is almost always a tripped battery protection circuit, not a failed cell. Li-ion packs at this capacity have an onboard BMS that latches off if the pack was stored deeply discharged — the charger sees zero voltage, gets confused, and never initiates the charge cycle properly. The fix is to connect the charger, leave it for 20–30 minutes without touching anything, then disconnect and reconnect it once to reset the handshake. If the charge indicator still shows nothing after two reconnect attempts, check the charger output pins for continuity — a dead charger is more common here than a dead pack.

The cutting head on my Wolf AGS rotates fine but the blades feel weak even with a new battery — is the replacement pack the wrong fit?

A new pack that delivers weak cut force usually means the replacement voltage is slightly under-spec for the motor winding — even a 0.5V deficit under load causes noticeably reduced torque on a small shears motor. Double-check that the replacement pack is rated at 10.8V nominal, not 7.2V; the original Wolf AGS shipped with a 7.2V configuration but this replacement is spec'd at 10.8V, and fitting a lower-voltage pack will produce exactly this weak-but-running symptom. Measure the open-circuit voltage of your replacement pack with a multimeter: it should read between 11.5V and 12.6V when fully charged.
