SKU: BRBTM393
MPN: TM393
The Braille Auto Battery 12-Volt Lithium Battery Charger (Model TM393) is a dedicated charging solution engineered for lithium-ion 12-volt battery systems. Rated at 6 amps with a nominal output of 12.8–13.2 volts, this charger delivers consistent, controlled charging current for modern lightweight battery applications where traditional lead-acid chargers fall short. The unit features indicator lights for real-time charging status monitoring, allowing operators to verify charge progress without opening the battery enclosure or disconnecting the system.
At 6 amps output, the TM393 strikes a practical balance between charge speed and thermal management—fast enough for operational readiness but measured enough to avoid stress on compact lithium cells. The 12.8–13.2V output window is precisely calibrated for lithium chemistry, preventing overcharge damage that occurs when standard chargers misread voltage thresholds. Weighing only 2.64 pounds with compact dimensions (7 x 3 x 9.75 inches), the charger remains portable for field deployment while maintaining the internal components necessary for precision voltage regulation. Status indicator lights eliminate guesswork during charging cycles, critical in scenarios where battery condition directly impacts mission readiness.
This charger serves operators relying on lightweight lithium battery systems in power tools, backup lighting, communications equipment, or specialized tactical gear where weight savings matter. Law enforcement and military personnel increasingly adopt lithium batteries for their superior power-to-weight ratio and consistent discharge curves, but these systems demand proper charging infrastructure. Standard automotive or generic battery chargers risk damaging expensive lithium packs through voltage overshoot or incorrect termination algorithms. The TM393 addresses this requirement with voltage and amperage specifications designed explicitly for lithium-ion chemistry, ensuring battery longevity and safe operation across repeated charge cycles.
