I have been doing some lengthly tests over the years with some
batteries, mostly alkalines. I've tested three brands:
Rayovac
Energizer
RS Enercell
These were tested in a low drain application to see how long they would
last, and the same application was used for each brand, exactly the
same product.
The amazing results were:
Code: Select all
Rayovac 3 months
Energizer 4 months
RS Enercell 9 months
shot.
Funny too, because i picked up the Enercell batteries on a whim
when i bought something else and wanted to try it out in the
parking lot before i drove back home, just in case i had to bring
it back.
I've also tested their NiCds and found them to be very good (the
sub C size that cost about 10 dollars for two cells). They were
actually rated higher than they were stamped.
To contrast, i didnt like their NiMH cells at all and found them to
be extremely under rated (significantly lower than stamped).
I dont buy them anymore for that reason.
