The Saker mini chainsaw is a popular cordless electric chainsaw that runs on a rechargeable lithium-ion battery. With its compact size and cordless convenience, the Saker mini chainsaw is designed for light-duty cutting tasks around the yard. One of the key specs that chainsaw owners want to know is how long it takes to fully charge the battery. A fully charged battery is essential to getting the most cutting time from your Saker mini chainsaw before needing to recharge again. In this article, we will provide a detailed breakdown of how long you can expect it to take to charge your Saker mini chainsaw battery from fully dead to 100% charged.

Saker Mini Chainsaw Battery Specs
The Saker mini chainsaw comes equipped with a 2.0Ah lithium-ion battery pack. This battery pack is designed to provide enough power and run-time for the chainsaw to tackle small limbs and branches around the yard. Here are the key specs for the Saker mini chainsaw’s battery:
- Battery type: Lithium-ion
- Battery voltage: 20V
- Battery capacity: 2.0Ah
- Charger input: 100-240V AC 50/60Hz
- Charger output: 24V DC 0.75A
The voltage of the battery determines the cutting power of the motor, while the amp-hour (Ah) capacity determines how long you can expect the battery to last on a single charge. With a 2.0Ah battery, Saker estimates the mini chainsaw should provide up to 30 minutes of run-time. However, the actual run-time can vary depending on how continuously you are cutting and the thickness of the material being cut.
Charging Time from Dead Battery
When the Saker mini chainsaw battery is completely dead, how long will it take to recharge back to a full 100% charge? There are a few factors that influence total charge time:
- Remaining charge – If the battery still has some charge left, it will take less time than a fully dead 0% battery.
- Battery temperature – Charging is slower at extreme cold/hot temperatures.
- Charger amperage – Higher amp chargers provide faster charging.
Given ideal conditions of charging a fully dead 0% battery with the supplied Saker charger, you can expect a charge time of around 60 to 90 minutes.
Here is a more detailed breakdown of approximate charge times starting with a fully depleted battery:
| Charge Level | Charging Time |
|---|---|
| 0% to 25% | 15 to 20 minutes |
| 25% to 50% | 15 to 20 minutes |
| 50% to 75% | 15 to 20 minutes |
| 75% to 100% | 15 to 30 minutes |
| Total (Dead to Full) | 60 to 90 minutes |
As you can see from the table, charging times are fastest when the battery is at a lower state of charge. It takes about 15-20 minutes to go from 0% to 50%. The last 25% of charging slows down and can take 15-30 minutes to finish. This is due to the charging circuitry making adjustments to avoid overcharging as the battery reaches max capacity.
It is normal that the Saker battery will take about 1 to 1.5 hours for a full recharge from empty. Leaving it charging overnight is ideal to ensure it is topped up and ready for yard work in the morning.
Charging Tips
Here are some tips to help ensure efficient and fast charging of your Saker mini chainsaw battery:
– Recharge at room temperature – Avoid charging in extremely cold or hot conditions. Ideal temp range is 50°F to 85°F.
– Use the supplied charger – It is designed to charge at optimal levels for your specific battery. Other generic chargers may charge improperly.
– Don’t interrupt charging cycle – For fastest charge, allow charging to complete fully before disconnecting.
– Store battery at 40-50% charge – For long-term storage, avoid storing the battery at full 100% charge. 40-50% is ideal for minimizing battery degradation.
– Charge fully before first use – Be sure to fully charge the new battery before using your chainsaw for the first time.
How to Tell When Battery is Fully Charged
So how can you tell when the Saker mini chainsaw battery is fully juiced up and ready to use? Here are some ways to check battery charge status:
– Charging light turns green – The charger has an LED light that will turn from red to green when charging is complete.
– Charger fan turns off – The internal cooling fan will turn off when done charging.
– Battery gauge shows full – Press the battery indicator button to check charge level.
– Voltage reads over 20V – Check voltage with a multimeter to confirm over 20V.
– Run chainsaw – Fully test by running the chainsaw to ensure adequate power and run-time.
Once charging is complete, the battery will maintain its charge for several months if left unused. However, it’s best to recharge every 2-3 months when storing long-term.
Maximizing Battery Life
To get the most service life out of your Saker mini chainsaw battery, follow these tips:
– Don’t drain completely dead – Recharge before fully empty to avoid deep discharges.
– Store battery at 40-50% – Avoid storing at full charge for long periods. 40-50% charge minimizes degradation.
– Avoid overcharging – Don’t leave on charger for days on end after full charge is reached.
– Use proper charger – Always use the matching Saker charger for optimal battery life.
– Clean battery contacts – Keep contacts free of dirt and debris for proper connections.
– Store battery properly – Store battery pack in a cool, dry place between uses. Avoid temperature extremes.
– Limit heavy loads – Avoid extremely long cuts in thick or green wood that overwork battery.
Following those simple guidelines will help get the longest life out of your Saker mini chainsaw’s lithium-ion battery. With proper care and charging habits, you can expect the battery to last 3-5 years or more.
Conclusion
In summary, you can expect a full recharge of the 2.0Ah Saker mini chainsaw battery to take around 60-90 minutes using the included charger. The final 25% of the charge will be the slowest. To keep your battery lasting for years, take care to store it properly between uses, recharge fully before first use, avoid fully draining, and don’t leave on the charger indefinitely after a full charge is reached. Following the usage and charging recommendations covered in this article will ensure your Saker battery is always ready to tackle your next yard project.
