Your battery might be bad, or so might the alternator, or both. A bad alternator will ruin a good battery over time, and vice versa.
The voltage regulator and or the alternator are bad. You need to have these items checked. Make sure the wiring is in good shape and battery cables are in woking order.
Don't charge it frquently.
something is causing a drain on the battery when switch is turned off
ALTERNATOR OR THE BATTERY GROUND WIRE Have you tried checking your Alternator? I know this is why mine on my vehicle would not stay charged..
Because the ignition is powered directly from the battery. The Gen/Alt only feeds the battery.
Something is on draining the battery or it has a dead cell and needs replacing.
Either the charging system has failed or the battery is bad.
Altenator is not charging battery!!
how long do batterys work for a car?
Dead cell in battery or something is on pulling power from the battery. Disconnect the negative battery cable overnight with the battery fully charged (12.6 volts). If the battery is dead the next morning it has a dead cell and needs replacing. If however the battery is still fully charged then a light is on somewhere or a relay is stuck closed.
Dead cell in battery, loose of corroded battery connections, or the charging system on the mower engine is defective.
Sulfation can happen when battery is not fully charged and remains discharged
