Are battery-powered sprayers worth it over a hand-pump model?

For larger lawns and frequent use, the consensus across r/lawncare and verified-purchase reviewers strongly favors battery power because it eliminates fatiguing manual pumping and delivers more consistent pressure. For small yards or occasional spot-spraying, reviewers note an inexpensive hand-pump tank does the job for a fraction of the cost. Battery units do add weight and introduce a pump/battery that can eventually fail, a complaint that appears across community threads.
