Yep. Battery is most important. If you're like me and have all types of battery tools (impact wrenches, grease gun, leaf blower, string trimmer, and on and on), it's always good to stay in your "eco system". For me, it's DeWalt. I rarely (maybe 3 or 4 times a season) use my walk behind Honda mower. It's a GREAT mower but......................I still have yet another piece of gas powered outdoor equipment that needs my attention every year not to mention fresh fuel and so on. So, at some point I too will be looking at an electric walk behind. But, it will likely be DeWalt.
As for Consumer's Reports. I take everything they publish with a HUGE grain of salt. REALLY HUGE. They claim they don't take ad $$$$ but what they don't disclose is who is paying off their Board of Directors.
I discovered this garbage years ago. I was looking at a new dishwasher. Oddly at the time, all the Kenmore products were made by Frigidaire. I even found 2 absolutely identical machines down to the nth degree. One Frigidaire and one branded Kenmore. CR rated the Frigidaire as "unacceptable" yet the VERY SAME Kenmore got their top ratings!
I was doing new construction at the time with my business partner. We were installing Kenmore appliances in all our new homes. I talked to our rep about this. He said "it's simple". Some of the staffers and higher ups at CR are actually big wigs with Sears. So, they always get the nod on appliances. Then and there I stopped putting any faith in CR and never will.
End of rant. Anyway pay attention to your battery ecosystem. If you don't have one yet and are planning on doing more battery equipment and tools just be sure you can use your batteries X Platform IOW, run your mower, your blower, your impact wrench, cordless vacuum, etc.
