Went to an electric chainsaw last year and when the weedeater died went with the dewalt as well. Now have like 7 dewalt batteries to feed my impact, impact driver, drill, light, chainsaw, fan, weedeater etc. I was worried about battery life with the weedeater, but the 9Ah battery it comes with will do the yard twice (45 minutes to an hour each time) before needing a recharge.
