Frequently Asked Questions
How long does a 7-amp 12V DC battery last?
The battery life depends on the power consumption of your specific access control system and its usage frequency. A basic system can run for up to 12 hours on a fully charged 7-amp battery.
You can estimate the runtime by adding up the total power consumption of your components. For example, a system with a magnetic lock (500mAh) and a keypad (50-130mAh) consumes approximately 630mAh (or 0.63A) per hour.
Calculation: 7Ah / 0.63A ≈ 11.1 hours.
