STIHL HSA 65 Cordless Hedge Trimmer Review

Although the STIHL HSA 65 Cordless Hedge Trimmer was just released in July 2010, by October of the same year it had already won the prestigious Popular Mechanics Breakthrough Award. This award recognizes the most usefully unique products of the year. The award was given to the HSA 65 primarily for the fact that this hedge trimmer was the first product to take advantage of STIHL’s new 36-volt lithium-ion battery-power technology. This technology allows the hedge trimmer to operate cordlessly with enough electrical power to compare to trimmers running on combustion engines. The key benefit is that there is absolutely zero emissions released by the trimmer.

The STIHL HSA 65 Cordless Hedge Trimmer is ahead of its time. For those who have been holding back from buying a cordless hedge trimmer because the power and dependability just wasn’t there, now is the time to rethink the purchase. STIHL has advanced the technology to with its 36-volt lithium-ion battery system to give pruners the power and flexibility they have been looking for.

Environmentally Friendly

The STIHL HSA 65 is ideal for anyone who is looking to live as environmentally as possible in the modern world without having to give up any of the luxuries. This model of hedge trimmer is already used by professional landscapers, government agencies, amateur gardening enthusiasts, and just the average consumer who has hedges needing trimmed. Not only does this model benefit from having no emissions, it also produces no noise pollution. The HSA 65 is up to four times quieter than gasoline-powered trimmers.


The HSA 65 cordless trimmer combines the power of the 36-volt battery system with state-of-the-art diamond-ground blade edges. These highly honed blades provide clean, precise cuts and high speed. This means you will not only save money by not having to buy fuel, but you will save time because the trimmer is so efficient.

In total, the double-sided blade with integrated cutter guards is 20-inches in length, which is perfect for most every situation. It provides a generous 20-inch cut depth while still being wieldy and maneuverable for sculpting, shaping, and general trimming. A tip protector is included to help prevent accidental contact with other objects that can damage or dull the blade.

Battery and Charger

The lithium-ion battery used by the STIHL HSA 65 is very impressive at 36 volts. It ensures strong performance of the trimmer, but it also has an extremely long usage time between charges. The battery has been tested to be capable of being recharged hundreds of times at the original power level. Thereafter, the capacity will slowly diminish, but remain quite usable for hundreds of further recharges. The only drawback about the battery and charger is that they are both sold separately. That means all three items, the trimmer, the battery, and the battery charger, must be purchased separately to have one complete working unit. While this is more of an annoyance than anything, it requires the buyer to figure in the price of the battery and charger to get a total. The battery, known as the AP 80 Lithium-Ion Battery, has the following features:

• 36 volts of power
• Lightweight at only 2.5 pounds
• Run time of 30 to 45 minutes when used in conjunction with the HSA 65
• No major charge loss during storage
• Easy-to-read LED charge level indicator
• Voltage monitor ensure an extended lifespan and reliability in operation
• Temperature sensors prevent overheating and overload the battery

The standard charger used for the HSA 65 and AP 80 battery is the AL 100. However, the AL 300, a rapid-charging upgrade, is also available. The AL 100 has a 70 minute charge time, whereas with the AL 300, the charge time drops to 25 minutes. Both chargers have an LED indicator and switch off when the battery is fully charged to prevent overcharging.


A useful accessory for the STIHL HSA 65 that is also sold separately is the STIHL Battery Belt. This belt is lightweight and has a bag attachment to hold one battery, an electrical cable, and the battery adapter case. The advantage of this accessory is that the weight of the battery comes off the arms while using the hedge trimmer. The weight of the battery is displaced to the hips instead. Up to two additional bags can be purchased for the belt to carry extra batteries, thus extending the usage time between charges.


The STIHL HSA 65 Cordless Hedge Trimmer is a pioneer in its product category. Features include an instant start system and a built in hanging slot for easy storage. The precise specifications of this unit are as follows:

• Weight with battery: 10.6 pounds
• Blade length: 20 inches
• Strokes per minute: 3,000
• Emissions: none
