Everything I new about rechargeable batteries is now wrong!!

If any of you are like me then you were raised to believe rechargeable batteries have a memory effect nd you should fully charge and diischarge them to keep them woring well. 

That weas true until recently. I found out that lithium ion batteries work  the opposite way round. They have no memory effect and suffer if repeatedely charged and discharged fully. They also suffer if they're kept hot. 

Who knew. I certainly didn't. Atleast I do now.  checked and it seems all the batteries I am using are Lithium ion so I'd better start treating them right soon!!!
