Proper charging is crucial to keep your cordless chainsaw powered up and ready to go when you need it. With the right information and a few simple steps, you can get your Stihl chainsaw charger working again in no time.

In this guide, I’ll cover the common reasons a Stihl charger may not be working, how to identify the issue, inspecting both the battery and charger, maintenance tips, and preventing future problems. Let’s get started!

Stihl Chainsaw Charger Not Working: What Could Be the Problem?

Troubleshooting a Stihl Chainsaw Charger Not Working

When your Stihl chainsaw charger fails to charge the battery, there are a few likely culprits to consider first before taking more drastic measures. Here are some of the most common reasons a Stihl chainsaw charger may not be working:

Common Reasons for Charger Issues

  • Wrong or incompatible battery – Stihl chainsaws are designed for specific voltage and amperage batteries. Using an incorrect or incompatible battery pack can prevent proper charging. Always verify you have the correct Stihl battery for your model charger.
  • Dirty or damaged battery terminals – Corrosion, dirt, debris or damage to the battery terminal contacts can interrupt the charging process. Clean terminals ensure a good connection.
  • Battery temperature issues – Extreme hot or cold battery temperatures while charging may trigger the charger to stop charging as a safety precaution. Always charge batteries at room temperature.

Identifying the Issue

Before you can fix the problem, you need to identify exactly what is causing the charger to malfunction. Here are two easy ways to get more insight:

  • Check the user manual – The user manual for your specific Stihl chainsaw model will outline proper charging procedures, status light indicators, troubleshooting steps and compatible accessories.
  • Observe charger & battery behavior – Pay attention to any lights, sounds or messages on either the charger or battery. Note charging duration and if charging seems to start then stop.

Thoroughly inspecting both the battery and charger can also provide useful clues to pinpoint the issue, so let’s look at that next.

Inspecting the Battery

Since the battery is one part of the charging system, it’s important to check its condition when diagnosing charger problems. Here’s what to look for:

Ensuring Compatibility

  • Verify voltage & capacity – Make sure the battery specs match what is recommended for your Stihl chainsaw model to avoid incompatibility issues.

Cleaning Battery Terminals

  • Check for debris & corrosion – Use a wire brush to remove any dirt, corrosion or moisture from the battery terminal contacts to allow a clean connection.
  • Safely clean with baking soda – For more stubborn build-up, create a paste of baking soda and water. Apply to terminals, let sit 5 minutes, then scrub clean.

Battery Temperature Issues

  • Mind the temperature – Charge battery at room temperature whenever possible. Very hot or cold batteries may not charge properly.
  • Allow to normalize – If exposing battery to temperature extremes during use, allow battery to return to room temperature before charging.
  • No freezer storage – Do not store batteries below 0°C or freezing damage can occur.

So inspecting the physical battery for correct specifications, clean terminals and ideal temperature will help ensure successful charging. Now let’s examine the charger itself.

Inspecting the Charger

Since chargers are prone to wear and tear over time, carefully inspect your Stihl chainsaw charger for any issues or malfunctions. Here’s how:

Checking for Malfunctions

  • LED indicator lights – Check all charger lights for proper operation. Solid green generally means fully charged.
  • Connection points – Examine the charger terminal where the battery connects. Ensure the contacts are clean and undamaged.
  • Charging duration – Time how long the charger runs until indicating a full charge. Much shorter durations could signal issues.
  • Intermittent charging – Note if the charger starts charging then stops prematurely, which likely indicates a problem.
  • When to seek help – For repeated failures, unclear issues or safety concerns, contact your authorized Stihl servicing dealer for assistance.

Charger Maintenance

  • Proper handling – Always hold the charger by the housing, avoid straining cords, and prevent exposure to moisture or extremes.
  • Clean contacts – Use compressed air or rubbing alcohol to routinely clean out and remove debris from the charger terminal.
  • Check fittings – Ensure the charger terminal fits properly into the battery port without wiggling or gaps.

Taking steps to inspect both the Stihl battery and matching charger will hopefully reveal any underlying issues with the charging system. But prevention is also key for avoiding future problems, so let’s talk maintenance best practices next.

Preventing Future Charger Issues

To help avoid recurrent issues with your Stihl chainsaw charger, be diligent about regular upkeep and proper storage. Implementing the following prevention tips will extend the lifespan of both your battery and charger:

Regular Maintenance

  • Read the manual – Follow all usage, charging and maintenance directives in the Stihl operator’s manual. This will provide model-specific guidance.
  • Check connections – When charging, confirm the battery and charger interconnect cleanly without gaps or wiggle room.
  • Alternate batteries – Rotate between multiple batteries instead of charging one battery over and over to spread out wear.
  • Clean frequently – Periodically use compressed air and rubbing alcohol to clean the battery terminals and charger contacts every few months.

Proper Storage

  • Moderate temperatures – Avoid storing batteries or charger in extreme cold or hot conditions for prolonged periods.
  • Dry location – Prevent moisture damage by storing indoors in a dry area. Never submerge charger in water.
  • Preventative measures – When not in use, cover charger contacts and disconnect batteries left in storage to minimize corrosion.
