Purpose-built for 12V GILL G-series and LT 7000 aviation batteries, the 128CEC2-AA-S2 delivers intelligent 8-amp charging with automatic desulfation, temperature-compensated multi-stage logic, and an IP65-sealed enclosure rated for continuous hangar or flight-line use. It diagnoses battery condition on connection, recovers deeply discharged cells that basic chargers abandon, and maintains batteries indefinitely without overcharging.
Most battery chargers stop at bulk charging. The BatteryMINDer 128CEC2-AA-S2 goes further: it reads battery state-of-charge on connection, applies a multi-stage charge profile tuned for GILL sealed and wet-cell chemistry, then automatically transitions to float maintenance. Its pulse-type desulfation circuit actively breaks down lead sulfate deposits -- the primary cause of capacity loss in stored aviation batteries -- whether the battery is new or years old.
The unit uses industrially rated microprocessors and runs 24/7 without supervision. A built-in auto-temp compensation sensor (pre-installed) adjusts charge voltage from -4 deg F (-20 deg C) up to 122 deg F (50 deg C), preventing the undercharging common in cold hangars and the overcharging that destroys cells in summer heat. After any AC power outage, the charger automatically restarts and resumes its program -- no manual reset needed.
Engineered for GILL G-series and LT 7000 series 12V aviation batteries, both sealed and wet-cell types. No guesswork adjusting profiles or chemistry switches.
High-frequency pulse mode dissolves sulfate on new batteries and reverses sulfation buildup on aged or long-stored packs, restoring usable capacity.
Automatically detects weak or dead cells and flags batteries that cannot accept a charge. Identifies bad-cell batteries so you know when replacement is truly needed.
Dust-tight and protected against water jets from any direction. Rugged, vibration-resistant construction suits hangar floors, tie-down areas, and outdoor storage.
While optimized for GILL aviation batteries, the 128CEC2-AA-S2 is compatible with a wide range of 12V lead-acid chemistries:
The 128CEC2-AA-S2 uses a recovery mode that attempts to bring back batteries that have dropped below the threshold most chargers refuse to engage. If the battery has viable cells, BatteryMINDer works to restore it rather than giving up.
The 128CEC2-AA-S2 can maintain up to two batteries simultaneously when used with the optional BatteryMINDer splitter cable (part number 210-AY, sold separately). This makes it practical for aircraft with a primary and standby battery, or for maintaining two separate rigs from a single outlet.
The built-in eco-mode reduces power draw during float/maintenance phases, keeping electricity use low during extended storage periods without compromising battery health monitoring.
The 128CEC2-AA-S2 includes a full suite of passive and active protections:
Attach the included ring-terminal or SAE pigtail to your aircraft battery terminals during the season, then simply plug and unplug the charger as needed. This avoids repeated clip connections and keeps terminals clean.
Optional dual-battery splitter cable (part 210-AY) is sold separately and is not included.
BatteryMINDer backs the 128CEC2-AA-S2 with a 1-year 100% money-back guarantee and a 5-year "No Hassle" warranty against defects in materials and workmanship.
