Battery Life Calculator FAQs
How accurate is this battery life calculator?
Our calculator provides estimates based on standard battery calculations. Actual runtime may vary depending on battery age, temperature, and exact usage patterns. For critical applications, we recommend consulting with our battery specialists.
What’s the difference between Ah and Wh?
Amp-hours (Ah) measure charge capacity, while watt-hours (Wh) measure energy capacity. Wh accounts for voltage (Wh = Ah × V). Our calculator converts between both to give you a complete picture of your battery’s capabilities.
Why is Depth of Discharge important?
Regularly discharging a battery beyond its recommended Depth of Discharge (DoD) can significantly shorten its lifespan. Lead-acid batteries typically shouldn’t be discharged below 50%, while lithium batteries can often handle 80-90% discharge.
How can I extend my battery life?
To maximize battery life: avoid deep discharges when possible, keep batteries at moderate temperatures, use a quality charge controller, and match your battery type to your usage patterns. Our specialists can provide customized advice for your specific setup.
