If you don't have one, get one. I put a Sears DieHard AGM battery in my bike today and it is worth every cent spent. 40 degrees outside, road in the rain, sat out in the wet cold, 2 hours later touched the starter and it fired right up. The engine felt smoother at interstate speeds too.

And DON'T get the batteries plus one....


I was impressed a year ago - but it's failing (bought it feb) at low temperatures - but they won't replace it because when it's warm it puts out factory CCA specs...

And there it is...We have been telling new members this since Day One...
"First thing to do for your Vulcan is get an AGM M-F battery... "

Some just don't want to believe it makes a diffrence....until they get one.

Alot of new bikes now come with them as standard equipment, am guessing that because the specs of the Vulcan are a bit "old" they just continued to use the orginal specified battery in manufacture.

My bike sat for 4 weeks without being put on a charger, and in 30 degree weather fired right up too...

Starts right up, charges faster and for some reason I don't understand (or may be it's imagined) the engine runs better....not to mention I don't have to worry about topping off the battery and the possibility of acid drips. Why wouldn't you invest in one??

I guess it's the higher amp output of the AGM battery that makes our coils happier = a smoother running engine and better combustion.

I bought SEARS because I got 7 years of service out of a DieHard lead acid. Hope this battery does the same or better.

I'm all about the AGM battery. When I installed mine, I swore the hot start backfires disappeared.

It's good to be back on the forum! :D

ok, where's the best (cheapest) place to get one of these batteries. also how long will these batteries last?

AGM battery...

I swear by the Big Crank ETX15L Battery:
http://www.batterymart.com/p-Big-Crank-ETX15L-Battery.html

Read about the AGM battery technology here: http://www.vonwentzel.net/Battery/01.Type/index.html

A newer type of sealed battery uses "Absorbed Glass Mats", or AGM
between the plates. This is a very fine fiber Boron-Silicate glass
mat. These type of batteries have all the advantages of gelled, but
can take much more abuse. We sell the Concorde (and Lifeline, made by
Concorde) AGM batteries. These are also called "starved electrolyte",
as the mat is about 95% saturated rather than fully soaked. That also
means that they will not leak acid even if broken.

AGM batteries have several advantages over both gelled and flooded, at
about the same cost as gelled:
Since all the electrolyte (acid) is contained in the glass mats, they
cannot spill, even if broken. This also means that since they are
non-hazardous, the shipping costs are lower. In addition, since there
is no liquid to freeze and expand, they are practically immune from
freezing damage.

Nearly all AGM batteries are "recombinant" - what that means is that
the Oxygen and Hydrogen recombine INSIDE the battery. These use gas
phase transfer of oxygen to the negative plates to recombine them back
into water while charging and prevent the loss of water through
electrolysis. The recombining is typically 99+% efficient, so almost
no water is lost.

The charging voltages are the same as for any standard battery - no
need for any special adjustments or problems with incompatible
chargers or charge controls. And, since the internal resistance is
extremely low, there is almost no heating of the battery even under
heavy charge and discharge currents. The Concorde (and most AGM)
batteries have no charge or discharge current limits.

AGM's have a very low self-discharge - from 1% to 3% per month is
usual. This means that they can sit in storage for much longer periods
without charging than standard batteries. The Concorde batteries can
be almost fully recharged (95% or better) even after 30 days of being
totally discharged.

AGM's do not have any liquid to spill, and even under severe
overcharge conditions hydrogen emission is far below the 4% max
specified for aircraft and enclosed spaces. The plates in AGM's are
tightly packed and rigidly mounted, and will withstand shock and
vibration better than any standard battery.

Even with all the advantages listed above, there is still a place for
the standard flooded deep cycle battery. AGM's will cost 2 to 3 times
as much as flooded batteries of the same capacity. In many
installations, where the batteries are set in an area where you don't
have to worry about fumes or leakage, a standard or industrial deep
cycle is a better economic choice. AGM batteries main advantages are
no maintenance, completely sealed against fumes, Hydrogen, or leakage,
non-spilling even if they are broken, and can survive most freezes.
Not everyone needs these features.

Thanks for the link and a price that can hardly be refused for AGM: $55. I called the company and was told that Deka made the batteries but they could not put that on the battery. hmmmm

Apparently the battery worked for you; is it still working ok?



thanks

Does anyone know how long an AGM battery will actually last? I live in Tucson and this is the elephant graveyard for automotive batteries. Surely someone has worn one out by now.

I would rather replace mine before it fails than suffer the inconvenience of limping home one day.

Yes, it the most it sat for was 3 weeks - always starts right up. It's just about 1 year old now and still never needs a charge. I love it.

Sold.

Now i hafta figure out what to do with my battery tender :confused: Lately i have been using my battery charger/starter from Sears to start the Vulcan as it can't start up on its own in the colder weather. The Vulcan turns over fine but it just does not have enuf voltage perhaps to start. Once warm though it starts fine. Hopefully this $55 battery will be a cheap fix.

The battery box was sitting at the back door when i came home, UPS really hustled this thing in fast from Battery Mart. $55 plus ship and the battery is really made by Deka as that is the box it came in. Battery Mart said they could not advertise this as Deka. At work our fork lifts run on Deka batteries so figured they knew something.

Inside the box is a voltage sheet and my battery was about 12.58 volts or 75% charged. Figured not much would happen until fully charged but tried it anyway.

BOOM :wow:

Wow, that was my hard to start Vulcan and even the high idle speed is now faster. Let it run a little and then put it on the Battery Tender and do it right. 40 degrees out so may not ride anyway. Usually at 40 degrees the engine goes kerchunk kerchunk and may not start. So it gets a kick from my Sears charger with engine start boost.

i suppose any AGM battery will give the same results and if your well healed then go with a badged name brand. My dealer wanted about $120 for a battery, so you can see why i like this one.

Two down and two to go: changed the worn tire and battery, now it wants a R/R relocate and spline lube. Discussing Moly 60 with my mechanic is futile, so i gotta figure where i failed last year to take this spline thing apart.

Hopefully this Vulcan will turn me into a real bike mechanic :D

i'll be ordering one of these (Big Crank) real soon! is this "ETX15L" the size we need for our bikes?
Call their toll free number to confirm.

Click on the provided link, that battery worked for me. Just checked the carton and "ETX15L" is what is on my box.

How is your bike starting now? If it was like mine.......be prepared to be shocked. Wish everything could be fixed this easy.

i don't know how the bike is starting now. it's still in winter storage mode. the battery is not in the bike. the battery that i have for it, is at least 3 years old (this being it's third year), so i'm looking into replacing it with a mf one.

Just a note about the Big Crank, it's a tad shorter so, I cut a few pieces from a wooden paint stirrer to use as a shims so that the clamp down holds it down tight. The battery comes with some sort of red plastic thing that's supposed to be used for this but I found the small wooden shims easier to deal with.

hey, thanks for the heads-up and info. good deal!

I ordered one and it came in the Deka box. Not sure why they can't put it on the battery, but it is a Deka battery.
