I have been thinking about it more, and I may have been working it more than expected. It didn't seem bogged down, but it was certainly working compared to its full tilt sound. I have it set up for mulching, and I plan on switching over to bag when I get home, perhaps that will give me better efficiency. I want to make this work, as otherwise I have been very impressed by it. It has the ability to run both batteries at once, and that is what I did, I may start running it with the 2ah battery first, then switch to the 4 when it is done and put the 2 on to charge while I mow with the 4. Might get a little longer life out of it that way. I will give these ideas a shot and report back this evening when I can try it out after work.AFAIK, Li-Ion battery performance does not improve after several charging cycles. How hard was your mowing ? Was the mower running at full speed the whole time ? How long did each battery last ?
I am going to see what happens running each battery solo. IIRC the box states 85 minutes for run time, with both batteries running at once. Thanks for the thoughts.Does the Kobalt come a a 2Ah and a 4 Ah battery?
Any 'sense' or guess which battery may be discharging too quickly? There have been some reports of people getting bad batteries when buying the Greenworks mower.
Or, maybe your mower failed to switch over to the other slot?
perhaps try using and timing the small battery first, then use the large battery and time it. Indeed, you may need to try using/depleting the small batery first, put it on the charger, then use the large battery. When the large batt is depleted, the small batt may have 10-15 minutes of new energy.
But, you could have a discussion with Lowes about whether they want the entire package back, or just swap batteries if you can determine a battery is bad.
what run time does Kobalt advertise?
