I bought a radio shack multitester to check my batteries, primarily my
laptop batteries. First on my old dead battery of Toshiba laptop, they
had a positive and negative mark shown..so it was easy to check it out
with the tester. But I bought it to check my Dell battery that lasted 1
year to the day of the end of my warranty. Fortunately, i did get a
refurbished one in time. Disappointed that it only lasted a year and I
had only used it a total of maybe 10 hours with the battery on my last
vacation...10 hours in 1 year and poof it went. The battery does not
have a pos and neg shown like the toshiba one..so I cannot test it that
way. In the meantime, I was trying to check some AA and AAA batteries
that I had and was able to understand on how to test them..but I do not
know how to interpret the readings I used the ACV side with it set at
15. I really don't know what does numbers mean. The manual is a joke,
at least for those of us that have no experience. The line moved a
little to the right where it seem to end a couple of notches on that ac
15v scale. It read the same for the new battery as well, so what is it
telling me that its a 1.5v battery? How does one know if the battery is
weak or whatever? Does anyone know of a web site that can tell me what
those readings represent? I did a search in google but nothing came to
what I was hoping for.
