<table cellspacing="0" cellpadding="0" border="0" ><tr><td valign="top" style="font: inherit;"><DIV>Use caution here the battery cycles depends upon DOD and recharge rate. I have found that recharge rates over C/10 shorten battery life. And if you measure the recharge voltage absorb volts, you can not push even that hard except when the battery is low. Further charge voltage gets to high the charge efficiency get lower. </DIV>
<DIV> </DIV>
<DIV>As to generators any SI (spark ignition) engine (also called a premix engine) will have lower efficiency at lower loads, the CI (compression Ignition) engine is more tolerant of part load keeping its efficiency high at part load. </DIV>
