Battery/Electric vs Gas Chainsaw Chains: What's Different

There is no such thing as an “electric chain” or a “gas chain.” A chain fits a saw because it matches the bar and the drive sprocket — pitch, gauge and drive-link count — not because of what turns the sprocket. If a battery saw and a gas saw take the same bar, they take the same chain.

What decides the chain

• Pitch must match the drive sprocket and the bar’s nose sprocket.
• Gauge must match the width of the bar groove.
• Drive-link count must match the bar.

Our guide to pitch, gauge and drive links shows how to read them from the bar or the old chain.

An example of how little the power source matters: for its own CS300 cordless saw, Oregon lists a 3/8” Low Profile, .050” gauge, 56-drive-link chain as an alternative chain (Oregon FAQ). That is a standard chain size, not a battery-specific part.

Where battery and gas saws do differ

Narrow-kerf and low-profile chains. Chain makers size some chains for lower-powered saws. Oregon says its narrow-kerf systems need less power from the saw than standard ones, and describes its .325” Low Profile “Nano” chain as sized for battery-powered and compact gas saws (Oregon manual, pp. 65–66). So they are not battery-only: the same chain is meant for small gas saws too.

Narrow-kerf chain needs a narrow-kerf bar. Oregon says to use its narrow-kerf chain only with bars designed for it. Don’t fit it to a standard bar, even if the pitch matches.

Bar mounts. A brand’s battery and gas saws may use different bar mounts, so a bar from one may not fit the other even when the chain would. See bar mount codes.

Bar length limits. Each saw has a maximum bar length set by its maker. Oregon, for example, says not to fit a bar longer than 16” on the CS300 (Oregon FAQ). Check the manual before fitting a longer bar and chain to any saw, battery or gas.

What’s the same

• Oil. Every chain needs bar and chain oil, whatever drives it. See bar oil not flowing.
• Wear and sharpening. Wear limits, sharpening and break-in don’t depend on the power source. See when to replace a chainsaw chain.
• Low-kickback chain. Use a chain that meets your saw’s kickback requirements on any saw; the replacement section covers what the manuals say.

Before handling the chain, remove the battery, unplug a corded saw, or turn off a gas saw and let it cool.

Moving a chain between saws

A chain from a gas saw will fit a battery saw only if both use the same pitch, gauge and drive-link count. Two saws with the same bar length can still need different chains, so compare all three numbers, not the bar length.
