That shows that
currently "100% charge" is 3.5kAh,
but when it was new "100% charge" was 4.0kAh.
PS: "kAh" might be completely wrong, I suck at units.
If the battery has a nominal voltage of ~ 4volts ;
3.5kAH represents (3.5) . (4) kAVH = 14 kwatt.hours !;
3.5k mA H seems more likely.!
You may not be alone though; it is my impression that 'units' and a
of what a measurement 'is' and what a measure ' is' are given little
prominence outside of ,
courses like physics and engineering. Thus we have economists talking about,
" a good set of numbers' and IT people with a poor idea of what the
bytes at some;
location are finally intended to represent; in a particular context,
Beyond 'dimensional' balancing of equations ([M]^x,[L]^y,[T]^z must be
the same on both sides !);
I find it useful in unit conversions :
eg [newtons] = [kilograms.m.sec^-2] to remember (for example);
1 kilogram = 2.2 lb implies 1= 2.2[ lb.kg^-1] and
1 m = 3.28 ft implies 1 = 3.28[ ft.m^-1] thus
[newtons] = [kg.m.sec^-2].[2.2 lb.kg^-1].[ 3.28 ft.m^-1]
= .(2.2).(3.28) [lb.ft.sec^-2] .............. (kg and
= .(7.21).[lb.ft.sec^-2] = 7.2 [1lbl] ( pronounced
nb 1 lbf = 32 lbl;
-obviously not much call for metric to imperial conversion these days;
but the method is perfectly general !
