If your Anritsu equipment is showing signs of battery wear or you simply need a fresh start, this step-by-step guide is here to help. We’ll walk you through replacing the battery in devices that use the original Anritsu 633-75 battery, such as the MS2720T/MS2721A handheld spectrum analyzers, S331E/S332E cable and antenna analyzers, S361E/S362E network analyzers, and MW82119B PIM Master series. Note that the AQ7280 OTDR from Yokogawa uses a different battery type and isn’t compatible with this guide.
For a reliable and high-performance upgrade, we highly recommend the High Quality 7500mAh Battery Anritsu SM204. You can check it out and purchase it here: https://www.batteriestar.com/detail/Anritsu/SM204/1744359.

A battery replacement not only revives your device’s reliability but also ensures continued performance during intensive RF and microwave analysis.
What You’ll Need

- Screwdrivers: A set of precision screwdrivers to open the battery compartment.
- Anti-static Wrist Strap: To avoid damaging sensitive electronic components.
- Clean Workspace: Ensure you have a clutter-free area to work in, as small parts may be involved.
Step-by-Step Battery Replacement Process
1. Power Down and Disconnect
Before starting, ensure that your device is fully powered down and disconnected from any power source. This precaution minimizes the risk of electrical damage or personal injury.
2. Remove the Battery Compartment Cover
Locate the battery compartment on your device. Use the appropriate screwdriver to remove the cover carefully. Some models might have a removable panel secured with clips—gently pry them open if needed.
3. Disconnect the Old Battery
Once the compartment is open, disconnect the worn-out battery. There may be a connector or plug that secures the battery in place—detach it slowly to avoid damaging the contacts.
4. Install the New Battery
Take your brand new High Quality 7500mAh Battery Anritsu SM204 and align it with the connector. Firmly plug it in until you feel it secure. Make sure the battery fits snugly in the compartment without forcing it in.
5. Reassemble Your Device
After installing the new battery, reattach the compartment cover and secure all screws or clips back in place. Double-check that everything is correctly assembled.
6. Power Up and Test
Turn your device on to ensure that it recognizes the new battery. Check the battery level and run a quick diagnostic if available. Your device should now operate with improved battery life and reliability.
Maintenance Tips for Prolonging Battery Life
- Avoid Extreme Temperatures: Store and use the battery in moderate climates. Excessive heat or cold can reduce battery efficiency.
- Partial Charging: Instead of charging to 100% every time, consider partial charges (around 80% SoC) to extend battery lifespan.
- Regular Inspections: Periodically inspect battery connectors and contacts for dust or corrosion.
- Use Standard Chargers: Fast chargers are convenient but can accelerate battery degradation if used frequently.
