E-meters, We Love to Hate it! [RE-wrenches]

[Richard Perez, Home Power magazine]

<x-flowed>Hello John

Actually the same thing which makes the batteries last a long time 
and be efficient is the same thing which keeps the ampere-hour meter 
accurate--regular full battery recharges!

If there is only one thing that your customers learn it should be to 
totally recharge the battery at least once weekly. Even if they have 
to burn dead dinosaurs to do it.
