The budget path to a big-bar battery saw — $379 at Home Depot buys an 18" bar, a 6.0Ah pack, a rapid charger, and Ryobi's claim of more power than a 40cc gas saw with over 90 cuts per charge. It replaced the well-liked RY40580, and for the homeowner who clears a couple of storm-downed limbs a year and wants zero maintenance, dated Home Depot reviews are full of converts from cranky gas saws. The gripes in those same reviews are consistent and worth knowing: the chain derails and needs frequent re-tensioning more than any other saw in this class, the bar-retention knob works loose mid-session, and sustained cutting heats the 6.0Ah pack enough that it needs a cool-down before the charger will accept it — a real bottleneck if you only own one battery. Power is honest mid-pack: fine for 12" softwood bucking, laboring in big hardwood. You're trading refinement for price, and at $120-250 less than the comparable EGO, Milwaukee, and DeWalt kits, plenty of owners consider that a fair trade.

Best for: Budget-minded homeowners on the Ryobi 40V yard platform who cut occasionally and want the longest bar per dollar.

Manufacturer figures except the engine class and single-pass cut, which are derived here. What each spec means

  • $379 with 6.0Ah pack
  • 18" bar on a budget
  • 5-year warranty

What owners like

  • Cheapest 18" battery saw kit from a major brand — $120+ under EGO's 18" kit, half of Makita's XGT
  • 40V 6.0Ah pack shares with Ryobi's popular mowers, blowers, and trimmers
  • Claimed 90+ cuts per charge is realistic for light bucking, per owner reports
  • 5-year tool warranty — longer than DeWalt or Makita offer
  • Standard 3/8"LP/.050 62-link chain with cheap aftermarket replacements everywhere
  • Quiet, push-button operation that converts frustrated gas-saw owners in droves

Common complaints

  • Chain derailment and constant re-tensioning are the most repeated complaints in Home Depot reviews
  • Bar-retention knob loosens during use — owners check it every few cuts
  • Battery overheats under sustained cutting and must cool before recharging, stalling one-pack owners
  • Noticeably slower in hardwood than EGO, Milwaukee, and DeWalt's big saws — the 40cc claim is optimistic
  • Plastic-heavy build and a basic oiler reflect the price point; this is not a saw for weekly firewood duty

Questions owners ask

Why does the chain keep loosening or coming off?

Chain derailment and constant re-tensioning are the most repeated complaints in Home Depot reviews, compounded by a bar-retention knob that loosens during use. The workable routine: re-tension frequently during the new chain's stretch-in period, and check the bar knob every few cuts until you learn how yours behaves. Once the chain seats, it settles down for most owners — but this saw rewards vigilance.

Is the 90+ cuts per charge claim realistic?

For light bucking, yes — owner reports back Ryobi's number on smaller wood. The gotcha is heat rather than capacity: the battery overheats under sustained cutting and must cool before it will recharge, which stalls one-pack owners mid-job. If you plan multi-hour sessions, a second 40V pack (shared with Ryobi's mowers and blowers) solves both problems.

Does it really cut like a 40cc gas saw?

The claim is optimistic — it's noticeably slower in hardwood than the big saws from EGO, Milwaukee, and DeWalt. What it actually offers is the longest bar per dollar: an 18-inch bar, 6.0Ah pack, and rapid charger for $379, which is $120+ under EGO's 18-inch kit and half of Makita's XGT. For occasional cutters that trade is fine; for weekly firewood duty the plastic-heavy build and basic oiler aren't up to it.

Are replacement chains cheap?

Yes — it runs a standard 3/8 low-profile .050-gauge 62-drive-link chain with inexpensive aftermarket loops available everywhere. Given the fast-stretching factory chain and this saw's tensioning quirks, buying a spare loop up front is a good idea.

Who is this saw actually for?

Budget-minded homeowners already on (or starting) Ryobi's 40V yard platform who cut a few times a season — storm cleanup, the occasional downed tree, trail clearing. The quiet push-button operation converts frustrated gas-saw owners in droves, and the 5-year tool warranty outlasts DeWalt's and Makita's. Just match expectations to the price: this is the value play in big-bar battery saws, not the performance play.
