some may be not built differently, but may be designed differently. as for cutting teeth. for example, older elec vs newer and batts. in general, you have to know the specs of the chain and the requirements of the gas saw. if they match, no problem. should service well, all things considered. I don't use batt chain saws, but I do have an older Craftsman electric. it came with a chain that made it run very bumpity! PITA to use. so it dint get used much. sat stashed away in shop. recently, I decided to look back into it, could it be a good performer? motor great, power great, bar great... chain, not so great! so I ended up with a Stihl chain saw chain. think it is a 3/8ths pico. 54 links.
just yesterday, I finally got around to testing it out. performed perfectly. it runs and cuts as good as my lil Echo CS-271... which is a real hornet
of a saw. couldn't be happier, and now since I scrounge around in my neighborhood and often see small diam oak on side of road... it will be a 'go to' saw for quick cuts, etc. I think it can handle with reasonable efficiency up to 12" trunks or limbs. I use a lot of firewood for a southern urban resident. best advice is to just stop by a good arborist shop. they can further advise you.
electric, 110-v
