If you’ve decided to ditch gas-powered tools and transition to cordless-electric, good on you!
You’re not only saving yourself the heartache of constantly maintaining fussy engines but also doing saving the planet from harmful exhaust fumes.
While shopping for a cordless/battery snow blower, you’ll want to see how large a battery pack it comes with.
The size of the battery, typically measured in ampere-hours (Ah), will give indicate how much of a charge it can hold, and therefore, how long it can run your snow blower.
Cordless single-stage snow blowers come with 30V or 40V 4.0-Ah Li-Ion batteries.
Single-stage snow blowers usually don’t come with extra features, so they’re highly energy-efficient, and even the LED lamps hardly take up any battery power.
Assuming you’re running your cordless snow blower on fresh battery packs, it’ll supply enough power to run the tool for between 20 and 30 minutes on average.
However, as the battery grows older, it loses some of its storage capacity.
On average, a Li-Ion rechargeable battery will lose 20% of its storage capacity every year, forcing you to purchase a fresh set after two or three seasons.
In addition, Li-Ion batteries can only go through a finite number of fully charged and fully discharged cycles.
The max cycle count varies from battery pack to battery pack, but the average full-and-empty cycle range is between 300 and 500 cycles.
If you use your snow blower’s battery to power other tools, then it will lose its max charge capacity more rapidly.
In summary, a snow blower’s battery can last anywhere from 20 to 30 minutes per charge with a maximum life expectancy of up to three years or 500 cycles, whichever occurs first.
