Some cordless string trimmer models have two-in-one capability, meaning you can use them for multiple purposes. If you need to trim areas that your mower can't reach, or you want to be especially careful around your ornamental plants, you can use your two-in-one tool as a string trimmer.

The run time of the trimmer is 10-15 minutes per battery on a fully charged battery. Battery run time may vary depending upon factors including but not limited to charging conditions, battery maintenance, storage and environmental conditions.

A 4.0Ah battery will power a cordless line trimmer for up to 110 minutes. A 5.0Ah battery will power a cordless line trimmer for up to 140 minutes. A 7.5Ah battery will power a cordless line trimmer for up to 210 minutes.

String trimmers are used to trim the grass in tight spots that a lawn mower can't reach, like along a fence, under decks, or near delicate plants and shrubs. On the other hand, lawn edgers are used to clean up borders along sidewalks and driveways.

Clippers with Ni-Mh or Ni-Cd batteries will run for about one hour. Newer trimmers, on the other hand, when fully charged, will run between 20 to 40 minutes. To maximize the life of your trimmer battery, about every two months, run the trimmer completely down , and fully recharge overnight.

about two to three years The typical estimated life of a Lithium-Ion battery is about two to three years or 300 to 500 charge cycles, whichever occurs first. One charge cycle is a period of use from fully charged, to fully discharged, and fully recharged again.

Overcharging can damage a battery and shorten its life, and not all chargers shut off automatically. Don't Overheat Battery: Heat is deadly to rechargeable batteries and can even cause them to explode. If the battery gets hot to the touch, let it cool down before recharging or using.

20V tools and batteries are for low to medium demand use due to their size and amp/hour rating. They work in all applications but will have a more limited run-time and strength compared to 60V.

Electric Shaver Constant use will make them dull over time and that can result in skin irritation. Braun also likes to remind users that replacement parts for older models can become more difficult to find when nearing a decade old, hence the need to upgrade your unit every 7-10 years.

around 2-3 years A: Li-ion cordless tool batteries typically feature a 300-500 cycle life, which is around 2-3 years. Cycle life indicates how often a battery can be charged before losing its ability to retain a charge. Therefore, you can generally charge a Li-Ion battery at least 300 times before it needs to be replaced.

Battery Voltage The higher the voltage, typically, the more cells that are in the battery pack. So when comparing a 40V pack to a 20V pack, in most cases the 40V pack will have more cells which means more power capacity available.
