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.
Lithium-ion, like lead-acid, does not benefit from deep discharge-you will get longer life from lithium-ion chemistry by only discharging to 25-30% and re-charging to 80-90% - storing it at full charge (100%) for a long time is also not good-which is the topic of this forum, actually.
