Make an estimate of how long your cordless mower will run before needing to recharge. Enter your battery voltage, Ah rating, and mowing conditions to get an accurate runtime estimate in minutes.
Stop Guessing Your Mower's Limits
You're half way along with the cutting, and the mower starts slowing down normal battery drain. The Lawnmower Battery Runtime Calculator is here to end that guessing game once and for all. It gives you a transparent picture of how long your mower battery will last depending on its details and real mowing conditions.
A Simple Formula, Smarter Decisions
Simply input your battery's voltage (V), capacity (Ah), and your lawn mower's average power consumption (W). A straightforward physics-based formula calculates runtime in minutes and hours. No gobbledygook, no need to overcomplicate things — just useful output.
Because Mowing Conditions Matter
Grass isn’t always friendly. On a warm, dry day, you’ll get the best performance. But if your lawn is damp or thick, your mower works harder and drains faster. This tool adjusts for that automatically:
- Light & Dry: Full expected runtime
- Medium: Around 10% less runtime
- Difficult & Damp: Around 20% less runtime
So you’ll always have a realistic estimate, not the overly optimistic figure printed on the box.

Plan Ahead and Stay Charged
Use this calculator prior to mowing to plan your session. In case your runtime is limited, you can then split the lawn into areas or invest in a second battery. It is also helpful in comparisons when choosing between 2.5Ah, 4Ah, or 5Ah batteries, now you can view how much extra runtime you are actually buying.
Final Word Conclusion
And there you have it, your mower's actual stamina out in the open in a couple of clicks. Being aware of your battery runtime allows you to plan smarter, mow more efficiently, and avoid those dreaded half-done lawns.
