Understanding Your Braun Series 7 790cc-7 Shaver

Before we dive into the specifics of battery replacement, it’s crucial to understand what makes the Braun Series 7 790cc-7 a standout in the electric shaver market. This device features:

  • Intelligent Sonic Technology: It automatically adjusts the power based on the density of your beard, ensuring a thorough shave.

However, after years of service, users may find that the battery loses its charge. We will explore how to replace this battery effectively.

Why Replace the Battery?

Signs of Battery Degradation

The necessity for a battery replacement often arises from several common indicators:

  1. Decreased Run Time: If your shaver no longer lasts as long on a full charge as it used to, it might be time to consider a battery replacement.
  2. Slow Charging: A shaver that takes an unusually long time to charge or does not charge at all may indicate a failing battery.
  3. Constantly Needing to be Plugged In: If you find that the only way you can use your shaver is while it’s plugged into the power source, this is a strong sign that the battery has reached the end of its life.

Benefits of Battery Replacement

Replacing your Braun Series 7 790cc-7 battery offers several advantages:

  • Improved Performance: A new battery restores optimal performance, allowing your shaver to work efficiently.
  • Cost-Effectiveness: Rather than purchasing a new shaver, which can be quite expensive, replacing the battery is a more economical option.
  • Environmental Impact: Keeping your shaver in use reduces electronic waste, contributing to environmental sustainability.

Tools Needed for Battery Replacement

To successfully replace the battery, you will need the following tools:

  • Small Phillips Head Screwdriver: This will be necessary for removing the screws from the shaver.
  • Plastic Opening Tools: These tools can help gently pry apart the shaver without causing damage.
  • New Battery: Ensure you purchase a compatible replacement battery for the Braun Series 7 790cc-7. It’s advisable to buy from reputable sources to ensure quality.
  • Soldering Iron: If the battery is soldered into place, a soldering iron may be needed to detach it.

Step-by-Step Battery Replacement Instructions

Step 1: Prepare Your Work Area

Find a clean and well-lit area to work. Lay down a soft cloth to prevent any scratches on your shaver. Make sure to have all your tools within reach.

Step 2: Disassemble the Shaver

  1. Remove the Head: Start by pulling the shaving head off. Most models allow for easy removal; this gives you better access to the body of the shaver.
  2. Unscrew the Back Panel: Use the Phillips screwdriver to remove the screws located on the back of the shaver. Set the screws aside in a safe place so you don’t lose them.
  3. Pry Open the Body: With the opening tools, carefully pry apart the shaver’s casing. Work gently to avoid damaging any internal components.

Step 3: Detach the Old Battery

  1. Locate the Battery: Once opened, locate the battery inside the shaver.
  2. Disconnect the Battery: If it is connected with wires, gently pull the connectors apart. If it is soldered, you may need to use the soldering iron to detach it.
  3. Remove the Battery: Carefully lift the battery out of the compartment.

Step 4: Install the New Battery

  1. Insert the New Battery: Place the new battery into the compartment in the same orientation as the old one.
  2. Reconnect the Battery: If it has connectors, plug them back in. If soldered, carefully solder the wires in place, ensuring that you do not create any short circuits.

Step 5: Reassemble the Shaver

  1. Close the Casing: Align the two halves of the shaver body and press them together gently.
  2. Reinsert the Screws: Using your Phillips screwdriver, screw the back panel securely in place.
  3. Reattach the Shaving Head: Finally, snap the shaving head back onto the unit.

Step 6: Charging Your Shaver

Once you have completed the assembly:

  • Plug in the shaver and let it charge fully before your first use.
  • Depending on your new battery, it may take several hours to achieve a full charge. Follow the instructions that come with the new battery regarding initial charging.

Maintenance Tips for Prolonged Battery Life

To ensure the longevity of your new battery, consider these maintenance tips:

  1. Regular Charging: Even when not in use, it’s beneficial to charge your shaver every month to keep the battery in good condition.
  2. Clean the Shaver: Regularly clean the shaving head and the interior of your shaver to prevent buildup that can strain the motor and battery.
  3. Store in a Cool, Dry Place: Avoid exposing your shaver to extreme temperatures, as heat can shorten battery life.
