🔋 Lithium-Ion Battery Conditioning

For optimal electrochemical performance, new lithium-ion batteries should undergo 2–3 complete charge and discharge cycles before reaching full capacity.

This stabilization phase allows the internal cell chemistry to achieve balanced ion distribution, ensuring maximum runtime, stable voltage output, and extended cycle life.

After this initial conditioning period, no further full discharge cycles are required.

Frequently Asked Questions (FAQ)

Q: Will this battery work with my Anritsu MS2721 spectrum analyzer?

Yes. SM204 is the official battery for the MS2721, MS2722, MS2723, MS2724, MS2725, and many Spectrum Master / Site Master models (e.g., MT9090, MT9083). Check your current battery label – if it says SM204 or has the same voltage/capacity, this is the direct replacement.

Q: How do I replace the battery? Is it user‑serviceable?

Yes, it’s external and tool‑free on most models. The MS2721 has a battery compartment on the bottom or back. Press the release latch, pull the old battery out, slide the new one in until it clicks. No tools needed – you can swap in seconds, even in the field. For other models, refer to your user manual.

Q: How long does a full charge last after replacement?

4–5 hours of continuous spectrum analysis with typical settings (50% backlight, GPS off, moderate sweep speed). GPS, high backlight, or active OTDR will reduce runtime. You’ll get back to the original battery life when the instrument was new.

Q: Is this battery compatible with the original Anritsu charger (e.g., the AC adapter or vehicle charger)?

Yes. It charges perfectly with the original Anritsu power supply and any compatible Li‑ion charger designed for the instrument. No modifications needed.

Q: Can I use this battery in extreme weather (hot tower, cold rooftop)?

Yes. It meets the same temperature specs as the original (-10°C to 50°C / 14°F to 122°F). For best performance, avoid leaving the instrument in a closed vehicle on a hot day. In freezing conditions, keep spare batteries in an inside pocket.

Q: What if my instrument shows a battery error after installation?

First, ensure the battery is fully seated (click). Plug in the charger and let it charge for 2 hours. If the error persists, try cleaning the battery contacts with a dry cloth. In rare cases, a firmware update (via Anritsu Customer Support) may be needed. Still not working? Contact us – free replacement under warranty.

Q: Do you offer discounts for field service teams or test equipment rental companies buying multiple batteries?

Yes. For orders of 5+ batteries, contact us for a quote. We work with telecom contractors, spectrum monitoring teams, and test equipment resellers.
