Hello Jersey paul,

We are sorry to hear that you were not completely satisfied with the run time of this battery. The run time varies depending on the tool that it is being used in but also the load acting against the unit while in use.

For best results users should:
1) Mow when the grass is dry.
2) Mow in the morning or late afternoon to reduce the heat stress on the newly cut grass.
3) Alternate mowing patterns each time you mow. As grass develops a grain based on your cutting direction it will lean towards the direction of your mowing path. Changing the pattern allows better vertical growth and helps to keep the cut neater.
4) Consider mulching. To mulch, remove the bag and insert the mulch plug into the rear of the unit. This will leave the clippings on the lawn allowing the nutrients and nitrogen contained within them to return to the soil and allow the remaining grass to recycle them (always discharge the mulch towards a previously cut area to prevent your mower from bogging down).
5) Always keep in mind what conditions your variety of grass prefers. If your grass prefers cooler climates, reduce the frequency with which you mow and increase the cutting height of your mower during hot seasons to compensate for the reduced growth rate these varieties may experience in this type of weather.

We would be happy to investigate to see whether your run time would be considered average; please kindly contact by phone at 1-888-909-6757.
