Honda Lawn mower battery keeps dying
If your Honda lawn mower battery keeps dying, the battery itself is the first thing to check. A weak or defective battery may have one or more dead cells, so try charging it fully with a charger first. If it still will not hold a charge, the battery needs to be replaced. If the battery tests good, move to the charger and confirm it is putting out the proper voltage with a multimeter, and make sure the outlet has power and has not tripped a breaker. On a Honda riding mower battery will not stay charged issue, the next most likely cause is the alternator, which should recharge the battery while the engine is running. If alternator output is low, you may be dealing with a mower battery not charging problem. After that, inspect the voltage regulator, since it controls how much charging voltage reaches the battery and can cause the lawn mower battery drains complaint if it fails.

02 - Honda 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 - Honda 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 - Honda 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.
