Thuraya SO-2510 Compatible Battery 3.7V 1100mAh AM000717

Up to 21% off
New arrival
From $30.99 USD $38.99
Shipping calculated at checkout.
Fits Thuraya SO-2510, SO-2520, SO-3319, and TG-2520 satellite phones; replaces OEM part numbers AM000717 and AM010084.
3.7V, 1100mAh lithium-ion cell delivers 4.07Wh to power voice calls, SMS, and emergency location services on the SO-2510 platform.
Connector seats flush into the battery slot on the SO-2510 body with positive terminal forward; locking tab engages from the rear.
We bench tested this cell in a SO-2510 unit and confirmed the BMS accepted full charge without fault codes; no load shedding observed during satellite acquisition.
In sub-zero field conditions, keep the battery warm in an inner pocket before use — Li-ion internal resistance spikes below 0°C and the satellite acquisition current draw can trip the BMS on a cold pack.

It took a bit longer than expected, likely due to the holiday season, but that was understandable. So far, the battery seems to be working well!

Battery Care Tips

🔹 Getting Started

Charge your new battery fully before you use it for the first time. Over the next few charge cycles, run your device down to around 20% before you recharge—this helps the battery perform its best. After that, charge whenever you need to.

🔹 Keep It Healthy

Avoid letting your battery completely drain or staying plugged in constantly. Both extremes wear it out faster. Store the battery in a cool, dry place when you're not using it, since heat damages batteries quickly.

Delivery and Shipping

🔹 Most orders ship the next day, and we use FedEx, UPS, Purolator and other carriers to get them to you. Lithium batteries have to ship by ground only, not air or USPS. Make sure your address is right before you order, because if we have to send it back, you pay for shipping again.

Thuraya SO-2510 / SO-2520 / SO-3319 — 3.7V Li-ion Replacement Battery (AM000717)

This 3.7V, 1100mAh Li-ion battery replaces the OEM pack in the Thuraya SO-2510, SO-2520, SO-3319, and TG-2520 satellite phones. It fits the standard battery bay on all four models and uses the same connector and BMS handshake as the original AM000717 and AM010084 packs. Capacity is 4.07Wh — identical to factory spec.

  • SO-2510 / SO-2520 / SO-3319 / TG-2520 compatibility: All four models share the same 3.7V single-cell architecture, physical footprint (58.60 × 37.10 × 9.00mm), and BMS communication protocol. One battery covers the full group without modification.
  • Bench tested on actual hardware: We cycled this pack through satellite acquisition sequences on the SO-2510 — including the antenna deployment current spike and sustained transmit draw. The BMS held voltage without tripping at any stage of the test.
  • Cold-field pre-warming: Below 0°C, Li-ion internal resistance rises sharply. The satellite acquisition current spike can trip the BMS on a cold cell before a call even connects. Keep the battery in an inner jacket pocket until the phone is ready to use.

Why the SO-2510 shuts down during satellite acquisition

Satellite acquisition on the SO-2510 combines antenna deployment, initial radio scan, and signal lock — all within a few seconds. That sequence draws more current than steady-state voice transmission. An ageing or cold cell can't sustain the voltage during this spike, so the BMS cuts the output to protect the cell. The phone powers off before a single call goes through. A fresh cell rated to the correct 3.7V nominal handles this surge without the voltage sagging below BMS threshold.

Charger won't accept the pack after extended storage

Li-ion cells left unused for several months can self-discharge below the charger's acceptance voltage — typically around 2.5V on most Thuraya desktop chargers. The charger reads the low cell voltage as a fault and refuses to begin the charge cycle. This isn't a dead battery. Connect the phone itself to USB power rather than the standalone charger — the phone's internal charge circuit often applies a trickle current that brings the cell back up to acceptance voltage. Once the cell reads above 3.0V, the desktop charger will begin a normal charge cycle.

Frequently Asked Questions

My Thuraya SO-2510 drops off mid-call even though the battery showed charge — what's happening?

Sustained satellite transmission at maximum transmit power draws more current than the indicator circuit measures in standby. If the cell has degraded, voltage sags under that sustained load and the BMS shuts output before the display registers low battery. This is capacity fade, not a charging fault — the cell can no longer hold voltage under real transmit draw. Replace the pack and recheck; a healthy cell holds above 3.5V through a full transmission.

The SO-2510 takes much longer to lock onto a satellite than it used to, and the battery drains fast during the search — is the battery causing this?

Extended search mode keeps the radio at full scan power continuously, which is one of the highest-drain states the phone operates in. A cell with reduced capacity gets pulled down faster during that window, making the drain appear abnormal even if acquisition time is unchanged. Cold temperatures compound this — Li-ion capacity drops measurably below 0°C, shrinking the usable energy available for the search cycle. Warm the battery to room temperature before powering on in cold conditions and check that the antenna is fully extended to reduce acquisition time.

The SO-2510 shuts down the moment I step outside in cold weather, even with a full charge — what's the fix?

Cold air raises the internal resistance of a Li-ion cell. When the phone attempts satellite acquisition outdoors, the current spike hits a high-resistance cell and voltage collapses below the BMS cutoff — the phone shuts off instantly. This happens even on a cell that reads 100% indoors at room temperature. Store the battery in an inner pocket and insert it into the phone only when you're ready to make the call; a cell at body temperature can sustain the acquisition spike at or above 3.6V where a cold cell cannot.
