TechniSat BAT-PACK-DM16HD Compatible Battery 7.2V 2100mAh

TechniSat TechniTouch TV-SAT-Kombi-Analyser — 7.2V Ni-MH Replacement Battery (BAT-PACK-DM16HD)

This 7.2V, 2100mAh Ni-MH battery replaces the OEM pack in the TechniSat TechniTouch TV-SAT-Kombi-Analyser and TechniTouch 0000/3434. It fits the same form factor as the original BAT-PACK-DM16HD and restores field measurement capability where mains power is unavailable. Dimensions are 101.78 × 52.45 × 18.00mm — measure your existing pack before ordering if you are unsure.

• TechniTouch analyser compatibility: Both the TechniTouch TV-SAT-Kombi-Analyser and TechniTouch 0000/3434 draw from the same 7.2V rail and use the same battery bay geometry and connector orientation. One pack covers both variants without modification.
• Bench tested on actual hardware: We ran this pack through the TechniTouch power-on handshake and signal acquisition cycle. The BMS passed voltage validation at startup, and the instrument accepted the pack without throwing a battery fault flag during sustained RF measurement logging.
• Post-install calibration cycle: After fitting this pack, run a full calibration cycle through the instrument's system menu before field deployment. The TechniTouch maps battery state during calibration — skipping this step causes premature low-battery warnings on your first measurement session, even when the pack is fully charged.

BMS lockout after the TechniTouch sat unused in a carry case for months

Ni-MH cells self-discharge over time. A pack stored for several months can drop below the BMS recovery threshold — typically under 5.4V for a 7.2V six-cell pack — and the protection circuit enters a locked state. When this happens, the instrument either shows no battery indicator or fails to boot past the splash screen. Connecting the charger may show no charge activity at first. Leave the pack on charge uninterrupted for at least two hours; most BMS circuits will accept a slow trickle and begin recovery once cell voltage climbs above 6.0V.

During sustained logging sessions, the tuner, display backlight, and RF front-end all draw concurrently. This combined load causes voltage to sag across the cell pack, and if the BMS detects a dropout below the cutoff threshold, it trips and kills power — even if the charge indicator showed adequate capacity moments before. This is a load-response behaviour, not a faulty pack. Ensure the pack is fully charged before starting a logging session, and check that the battery contacts in the bay are clean and seated flush — resistance at the contacts worsens voltage sag under load.
