[QUOTE="pendlewitch, post: 1327188, member: 214663"] I don't :Mischievous: Marketing copywriters and technical proof-readers can mis-interpret and get things wrong occasionally and this is a classic example. The writer of that piece of 'advice' doesn't seem to know what a charge cycle actually is, let alone the implications of running a lithium ion battery completely flat. Have a look at this link and then make your mind up. I had a similar debate with some mates at the golf club about sealed lead acid batteries as well, and the same misconceptions abounded there. It was Nickel based batteries that had the issue of 'memory effect' etc etc etc and not Lithium. Compare the number of potential charge cycles expected between 100% depth of discharge (DoD) and 25% DoD.
