Small Engines (Lawn Mowers, etc.): Riding mower battery dead, shape thanks, good shape


Question
Thanks for the response. I'll do the voltage checks you suggest. As for the time between restarts, no. At the beginning we were starting it probably with only two or three minutes between starts. At that time I didn't know we could keep it running by setting the parking brake. Guess I should have read the manual. The cables and connections looked to be in good shape. Thanks again

-----Question-----
My mom has a White, Model one-1650 riding mower. She just had the battery replaced about a week ago because the old one had died. After using it today with about 15 starts the battery was unable to turn the motor over anymore.  The battery voltage was about 12.8 volts without the motor running. With the motor running at full throttle it was very slightly over 13 volts. Should the charging voltage be a little higher than that? Any idea what else may be wrong? Thanks.

 Hello Mike:

 Use your Tester and Check the Voltage when the Starter is Turning or Trying to Turn the Engine. If the Voltage Drops Below 10.0VDC then the Battery has a Bad Cell. If the Voltage Stays Above 10.0VDC then the Starter is Binding when Hot. Not having the Extras a Automobile has; a Mower Doesn't Charge as High. 13.0VDC is Good for a Riding Mower. Was the Engine Run for At Least 5 Minutes between each Restart? Are the Battery Wires in Good Condition? The Starter May be Dragging/Binding. Hope this Helps. I am here if you Require more Assistance. Let me know what Happens, Please. Thanks.

 Good Luck

 Hello Mike:

 You May have Drained the Battery. The Engine Must Run at Full Throttle to Start the Stator Charging and it Normally Takes 5 Minutes to Recharge the Voltage Lost from 1 Engine Start. Hope this Helps.

 Good Luck
