What Is a Battery Tender and Why Is It Essential for Excavators and Skidsteers?
A battery tender is a device that maintains the charge of a battery through a constant low-level current. It prevents battery discharge and prolongs life by keeping it fully charged without overcharging.
According to the Battery Council International, battery tenders are essential tools for ensuring optimal battery performance and longevity in heavy machinery. They help to manage battery health, especially in equipment that is not used frequently, such as excavators and skid steers.
Battery tenders work by providing a regulated charge to maintain battery voltage. They switch between charging stages, preserving battery health while preventing sulfation, a process that can reduce battery efficiency.
The National Renewable Energy Laboratory further defines battery maintainers as devices that can automatically adjust the charging rate. They enhance the efficiency and lifespan of lead-acid batteries commonly used in construction equipment.
Several factors contribute to the need for battery tenders, including inactivity of equipment, extreme weather conditions, and the natural self-discharge rate of batteries. These conditions can lead to rapid battery degradation.
Approximately 30% of battery failures in construction equipment arise from improper charging and maintenance, as noted by the Equipment and Vehicle Service Association. Ensuring consistent use of battery tenders could reduce this failure rate.
The broader impacts include decreased equipment downtime, reduced operational costs, and enhanced equipment reliability. This positively affects productivity and lowers maintenance expenses in the construction industry.
On multiple levels, battery tenders influence the economy by increasing equipment uptime and reducing replacement costs. Environmentally, they prevent battery waste by extending lifespan.
For instance, regular use of battery tenders can increase battery life by up to 50%, according to battery manufacturers. This reduction in waste benefits both manufacturers and operators.
To address issues of battery health, experts recommend regularly using battery tenders especially for infrequently used machinery. The Battery University emphasizes the importance of adopting maintenance practices for optimal battery care.
Additionally, implementing smart battery management systems can help monitor and extend battery life. Utilizing technology for voltage monitoring and developing preventive maintenance strategies are essential for proper battery care.
