The 2 amp hour batteries do not have much life to cut the grass, but should cut more than that!
I am able to cut my froont lawn and part of my back with a 2.5 hour.  I have 7500 SF

I got maybe a fourth of the yard with the 2 last season. Switch between batteries was seamless. Now have to wait until the 5 recharges.

Maybe I'm just slow today. What does "About 10K" mean? 10k what?

Chuck, have your mowing conditions changed since last season? Grass is real long, more wet, blade needs sharpening, etc, that could effect the run time of the 2 ah battery?

Sounds like a case of right tool(battery) for the job,  2ah will work with a mower, but I would only use it to finish up the end of a mowing job not as part of my main power supply for a mower.

Definitely not ideal. But it sounds like he used to be able to do all the mowing with just one charge on each battery. Now the 2 ah battery runs down after a very short mow (120 ft?) so he has to recharge the 5 ah at some point to finish the job.
Might be time for a new, larger, battery to compliment the other 5 ah battery.

I’d start with the 5 amp then switch to the 2. When it was exhausted, I’d get the 5 to finish. Early this season I’d use the 5 twice, 2 twice, then finish a small area with the 5. By August it was the 5, then the 2 for a pass or two Then wait for the 5 to recharge. 5 length seemed normal. But the two was vastly different.
