Solar battery maintainers are an effective solution for keeping batteries charged on equipment that sits idle for extended periods. Whether mounted on dozers, excavators, or military trucks, these devices prevent sulfation, reduce jump-starts, and extend battery life—especially in remote or seasonal operations.
Background and Industry Adoption
Heavy equipment often sits unused for weeks or months, especially in seasonal industries like agriculture, forestry, and construction. Battery drain from parasitic loads or natural discharge leads to dead starts, lost time, and premature battery failure. To combat this, solar battery maintainers have gained popularity among operators and fleet managers.
Manufacturers like PulseTech, Hardkorr, and Harbor Freight offer 12V and 24V models tailored for different machine voltages. The U.S. military has adopted 24V maintainers for tactical vehicles, making surplus units widely available. These systems are often mounted with magnets or brackets and removed during operation to avoid damage.
Terminology Note
Performance and Maintenance Tips
In Missouri, a self-employed operator used a 15W dual-voltage panel with a built-in controller to maintain both 12V and 24V systems. He noted that the panel kept batteries topped off even during cloudy weeks. In Iraq, a technician working at Camp Anaconda emphasized checking water levels before cranking machines that had sat for six months—even with maintainers installed.
Conclusion
Solar battery maintainers are a practical, low-cost solution for preserving battery health in heavy equipment. Whether using surplus military-grade units or budget panels with controllers, the key is proper installation, voltage matching, and routine checks. For operators in remote or seasonal environments, these devices reduce downtime, extend battery life, and simplify fleet management.

Terminology Note
- Desulfator: A circuit that breaks down lead sulfate crystals on battery plates, restoring capacity.
- Trickle Charge: A low-current charge that offsets natural discharge without overcharging.
- Charge Controller: A device that regulates voltage and current from the solar panel to prevent battery damage.
- Parasitic Load: Continuous power draw from electronics even when the machine is off.
- Series Wiring: Connecting two 12V panels to produce 24V output for dual-battery systems.
- Dozers and trackhoes: Panels are mounted on brush guards or under canopies using magnets. When operating in wooded areas, users remove the panels to prevent limb damage.
- Skid steers and mini excavators: Small 12V maintainers are used to offset parasitic drain. Machines without master switches benefit most.
- Military trucks: 24V systems are installed permanently or temporarily, often sourced from surplus channels.
Performance and Maintenance Tips
- Check water levels in flooded lead-acid batteries before startup, especially after long storage.
- Use a charge controller for panels over 20W to prevent overvoltage.
- Look for indicator LEDs or voltage readouts to confirm operation.
- Remove panels before transport or operation to avoid damage—several users reported torn wires from forgotten mounts.
- Monitor output current—1 to 2 amps is ideal for maintaining charge without stressing the battery.
