How do I select the right battery for my application? Proper battery selection may require the assistance of a knowledgeable battery sales/service technician. Contact your local Authorized Trojan DeaaFor a standard golf cart (3.5 HP motor and 250A motor controller), two batteries will go for 30-45 miles, whereas three batteries are good for up to 60 miles. One battery (not generally recommended except in lite use cases) will go for less than 30 miles with one person in the cart and no additional load in the cart. Actual driving range will vary depending on factors including, but not limited to, load, terrain, temperature and equipment.ler or call us at 1-800-423-6569 or 562-236-3000. What are the differences between a deep cycle battery, a starting battery, and a dual-purpose battery? A deep cycle battery has the ability to be deeply discharged and charged many times during its service life. It is designed specifically for powering electrical equipment for long periods of time. An automotive or starting battery is designed for brief bursts of high current and cannot withstand more than a few deep discharges before failure. This is why you can't start your car if you accidentally leave the lights on more than a few times. For applications where both engine starting and light deep cycling are required, a dual-purpose battery is often used. This type of battery is neither a starting nor a deep cycle battery but rather a compromise between the two that allows it to perform both functions adequately. Only deep cycle batteries should be used in renewable energy applications. What’s better 24 volt or 48 volt systems? Systems with loads greater than 100 watts continuous will be better served by higher voltages such as 24V and 48V due to the reduced size of wiring required to minimize voltage drop, which impacts overall system cost and ease of installation. Why do manufacturers use different alloys in their batteries (lead calcium, lead antimony, lead selenium, etc.)? The composition of the plate grid alloy can have a major effect on operating characteristics, such as behavior on float charging and cycle life. Older lead antimony designs have good cycling capability but require frequent water additions, particularly towards the end of life, due to antimony migration between the plates. Cells with lead calcium alloys require far less watering, but tend to have a poor cycle life. Lead selenium alloys are actually low-antimony types with the addition of selenium as a hardening agent. Such alloys promote good cycling capability, while maintaining a constant and fairly low level of water consumption. Many variants on these alloy types are commercially available.
