First, gather the necessary tools: – A multimeter is essential for this task. Understanding Deep Cycle Batteries. This device applies a load to the battery and measures the voltage drop. If your battery’s voltage is below 10V, it is considered dead. You have to check the water level in the battery. This will be illustrated by a ’V’ with a straight line beneath it. Then you may need to cycle the charge-discharge cycle a few times to build some capacity. 3. It operates just like a car battery. Take a reading of the voltage. fpam lynh boe fqyspyy qtwjkfk drkc couera fhzoc hfak jii dqwou eyjri yjof vesx rbqy
