However radiculopathy is not the cause of back pain, some of the major causes of acute and chronic low back pain (LBP) are associated with it. Spondylolisthesis is most common in the lower lumbar spine region. Causes are minor overuse trauma, particularly repetitive hyperextension of the lumbar spine.
Deep cycle batteries are designed to be discharged down as much as 80% time after time, and have much thicker plates. The major difference between a true deep cycle battery and others is that the plates are SOLID Lead plates-not sponge.
Generally speaking there are two different types of lead acid battery, Starting and Deep Cycle. If a starting battery is routinely deep cycled (discharged below 20%-50% of max capacity) it will generally fail after 30-150 cycles. The same starting battery will last for thousands of cycles if it is just used normally (2% - 5% discharge).
