Craftsman Lawn mower battery keeps dying
If your Craftsman lawn mower battery keeps dying, start with the battery itself, because a dead cell is the most common reason the battery will not stay charged. Try charging it with a battery charger first. If it still will not hold a charge, the battery is likely bad and should be replaced. If the battery checks out, move to the charger and confirm it is putting out proper voltage with a multimeter, and make sure the outlet has power and has not tripped a breaker. On a riding mower battery will not stay charged, the next likely causes are the alternator and the voltage regulator. The alternator should supply voltage while the engine is running and recharge the battery, while the voltage regulator controls how much charging voltage reaches the battery. If either part fails, you can end up with a lawn mower battery drains issue, a mower battery not charging condition, or a riding lawn mower charging problem that keeps coming back. Enter your Craftsman model number on RepairClinic.com to find the exact battery, charger, alternator, or voltage regulator that fits your mower.

02 - Craftsman Lawn Mower Charger
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.
Highly Likely
03 - Craftsman Lawn Mower Alternator
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.
Highly Likely
04 - Craftsman Lawn Mower Voltage Regulator
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.
Highly Likely
