FAQs
What is the difference between deep cycle and starting batteries?
Deep cycle batteries are engineered for regular discharges and recharges, making them suitable for applications that require steady power over extended periods. Conversely, starting batteries deliver short, high-current bursts to start engines but are not designed for deep discharges, which can shorten their lifespan.
How long can a 75Ah battery last on a full charge?
The runtime of a 75Ah battery depends on the power draw. For instance, if you draw 75 amps, the battery will last approximately one hour. Lower power consumption extends the battery life, so drawing ten amps, for example, would provide about 7.5 hours of use.
Can I use a deep-cycle battery to start an engine?
Although a deep-cycle battery can start an engine, it is not ideal. Deep cycle batteries are not built for the high surge currents required to start engines and could be damaged by such use over time. It is better to use a dedicated starting battery for this purpose.
How can I maximise the lifespan of my 75Ah deep cycle battery?
To prolong your battery’s lifespan, perform regular maintenance and avoid fully discharging it. Recharge promptly after use and ensure the battery is stored in a cool, dry location. Keeping the terminals clean and free from corrosion also helps maintain optimal performance.
What is the average lifespan of a 75Ah lithium battery?
A 75Ah lithium battery generally lasts 8 to 15 years, depending on how it is used and maintained. This longevity makes it a valuable investment for those seeking a reliable and long-lasting power solution.
