where are you getting 50$ batteries that aren't lawn tractor batteries?
( and I'm not doubting you.. i'm asking )
around here, between napa, car quest, auto zone, and discount auto, nad now oreilies.. a small car 12v battery is in the 65$ range.
walmart beats all of them by about 2 bucks on the low end.
a better universal sized truck battery is a whopping 89$
that's the size battery that fully fits all my 00/01 bat trays.. so it's what i buy on my converted machines. has the side benefit in that i can swap them in and outta my diesiel pickup truck ( 2 batteries ) to trade out during the winter so the bats don't just set there.
at work we are an interstate dealer and it's still 79$ for a 'truck' sized megatron.
we used to have a champion battery dealer nearby.. and those IMHO were a lil cheaper than walmart 'yellow' grade bats.
can't find them no more. where are you getting them?
no dekka dealers here either.
locally i can find 10/12 si alts for 29-35$ with a 10-15$ fore.. for a median price of 45$ + tax.. so the 50$ is about bang on for a 10si.
having a core on hand is helpfull. I've managed to grab a few free cores that i have seen set out at the dump... so that will save me 10-15$ if i need another'n.
