Husqvarna Lawn mower battery keeps dying
If your Husqvarna lawn mower battery keeps dying, the problem is usually the battery itself. A battery with one or more dead cells may take a charge from the charger but still will not hold it, so start there. If the battery checks out or a new one also goes dead, the next likely cause is a bad charger or a power issue at the outlet, so use a multimeter to verify charger voltage and make sure the outlet has not tripped a breaker. After that, look at the charging system on the mower. A weak alternator can cause a riding lawn mower battery will not stay charged because it is not sending enough voltage back to the battery while the engine runs. A failed voltage regulator can do the same thing by limiting or misdirecting charging output, leading to a mower battery not charging or a riding lawn mower charging problem. To find the exact Husqvarna battery, charger, alternator, or voltage regulator for your mower, enter your model number on RepairClinic.com and match your replacement part to your specific machine.

02 - Husqvarna 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 - Husqvarna 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 - Husqvarna 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.
