Examining Battery Contacts
Poor connections between the battery and vacuum can prevent proper charging:
- Remove the battery from the vacuum
- Inspect the metal contacts on both the battery and vacuum for:
– Dirt or debris buildup
– Corrosion (appears as green or white residue)
– Physical damage to the contacts - Check if the contacts are properly aligned when the battery is inserted
Dirty or corroded contacts can prevent the flow of electricity, making it impossible for your battery to charge even if both the battery and charger are functioning properly.
Testing Battery Voltage
For a more technical diagnosis:
- Remove the battery from the vacuum
- Set a multimeter to measure DC voltage
- Touch the probes to the battery contacts
- A healthy Dyson V6 battery should read approximately 18.5V when fully charged
- Significantly lower readings indicate a failing battery
This test can definitively determine if your battery needs replacement or if the problem lies elsewhere in the vacuum.
Step-by-Step Fixes for Charging Problems
After diagnosing the issue, follow these detailed solutions to get your Dyson DC59 charging properly again.
Cleaning Battery Contacts
Often, simply cleaning the contacts can resolve charging issues:
- Unplug the charger from the wall outlet

- Gently clean the metal contacts on both the battery and the vacuum
- Allow the alcohol to dry completely (usually takes only a minute)
- Reinsert the battery, ensuring it clicks securely into place
- Plug in the charger and test if charging begins normally
This simple maintenance step should be performed regularly to prevent charging issues from developing.
Performing a Battery Reset
Sometimes the battery management system needs to be reset:
- Power off the vacuum completely
- Remove the battery if possible
- Press and hold the power button for 15-20 seconds to discharge any residual power
- Reinstall the battery
- Connect the charger and allow the battery to charge fully
- Test the vacuum to see if normal operation has been restored
This process can help recalibrate the battery management system and resolve minor electronic glitches that affect charging.
Checking for Trigger Issues
In some cases, the trigger mechanism can affect charging:
- Unplug the vacuum from the wall
- Press and hold the trigger
- While holding the trigger, plug the vacuum back into the charger
- Observe if the charging behavior changes
- Release the trigger and check if normal charging resumes
Though trigger problems are uncommon in the DC59, this test can help identify if the trigger mechanism is interfering with the charging circuit.
Replacing the Dyson DC59 Battery
If diagnostics indicate a battery failure, replacement is the best solution. Here’s how to replace your Dyson DC59 battery safely and effectively.
Choosing the Right Replacement Battery
You have several options when selecting a replacement battery:
- Original Dyson V6 batteries: Cost approximately $96 plus tax and shipping
- Aftermarket options: Available at about one-third the price of originals
- 2100 mAh models match the original capacity but may fail quickly
- 3000 mAh models offer a good balance of price, runtime, and weight
- 4200 mAh models provide maximum runtime but are heavier
Most aftermarket batteries are compatible with the original charging dock and maintain the same indicator system as original batteries.
Battery Replacement Procedure
Tools Needed:
- New Dyson V6 compatible battery
- Small screwdriver (if necessary)
- Cotton swabs and rubbing alcohol for cleaning contacts
Steps:
- Unplug the vacuum from the power source
- Locate the battery release button (typically on the handle)
- Press the release button and carefully remove the old battery
- Clean the battery compartment contacts with alcohol and cotton swabs
