If your Huskee lawn mower battery keeps dying, the problem usually comes down to the battery itself, then the charger, followed by the alternator or voltage regulator. A bad battery can have one or more dead cells, so even after charging it with a battery charger, it still will not hold a charge. If the battery checks out, test the charger with a multimeter and make sure the outlet is supplying power and has not tripped a breaker. On riding models, a riding mower battery will not stay charged if the alternator is not producing the correct voltage while the engine is running, or if the voltage regulator is not sending enough charging voltage back to the battery. These are common causes behind a mower battery not charging, a lawn mower battery drains condition, or a riding lawn mower charging problem. Using your mower’s wiring diagram and a multimeter can help narrow it down fast.

To determine if the charger is defective, use a multimeter to test the charger for proper voltage output. In addition, test the outlet used by the charger, and ensure that the outlet has not tripped a breaker.
The alternator provides voltage to the lawn mower while the engine is running and also recharges the battery. To determine if the alternator is defective, use a multimeter to test the alternator voltage output according to the wiring diagram.
While the engine is running, the voltage regulator sends the proper amount of voltage from the alternator to the battery to keep the battery charged. If the voltage regulator is defective, the battery won't receive enough voltage, causing the battery to drain quickly.
