  2. Use high-quality batteries: If you have the option to choose between different batteries, opt for ones with higher energy density. Lithium-ion batteries, for example, tend to have a longer runtime compared to older battery types like NiCad.
  3. Maintain the battery's health: Avoid storing the battery in extreme temperatures, as this can shorten its lifespan. If the hedge trimmer is not in use for an extended period, store the battery separately in a cool, dry place. Clean the battery terminals occasionally to remove any dirt or debris that can affect the battery's performance.
  4. Optimize usage: Be efficient in your trimming tasks. Plan your cutting path to minimize backtracking or unnecessary passes. Avoid overexerting the hedge trimmer; if possible, use a manual tool for light touch-ups instead of firing up the cordless trimmer.
  5. Avoid heavy loads: Cordless hedge trimmers may struggle with thick branches or dense vegetation. Try not to force the trimmer through such situations as it will put unnecessary strain on the motor and drain the battery more quickly. Instead, use manual shears or a larger, more powerful tool to deal with heavy-duty cutting.
  6. Maintain the trimmer: Keep the blades sharp and clean. Dull blades require more energy to cut through branches, thus draining the battery faster. Regularly inspect the trimmer and remove any debris or sap that may accumulate on the blades, as this can impede performance and increase energy consumption.
  7. Use the appropriate speed setting: Some cordless hedge trimmers have adjustable speed settings. Use a lower speed setting when trimming lighter foliage and reserve the high speed for tougher branches. This will help conserve battery power.
  8. Monitor battery level: Some cordless hedge trimmers have a battery level indicator. Keep an eye on the battery level while working, so you can recharge or switch out batteries as needed. Avoid fully draining the battery, as it can negatively impact its overall lifespan.
