Battery facts:
One thing that destroys batteries fast is sulfation.
And this is the number one cause of all the battery issues people have with the Indians.
What is Battery Sulfation?
Sulfation, a build-up of lead sulfate crystals, is the number one cause of early failures of lead-acid, sealed AGM or flooded (wet cell-filler caps) batteries. A sulfated battery can lead to:
- loss of cranking power
- longer charging times
- excessive heat build-up leading to "boil out"
- shorter running times between charges
- dramatically shorter battery life
Sound Familiar????????
One of the ongoing topics of the above on this forum
What Causes a Sulfated Battery?
All lead-acid storage batteries will develop sulfate during their life time. This includes the new sealed "dry" such as Optima, Odyssey, Exide and Interstate branded AGM-spiral-wound types. Batteries develop sulfation each time they are used (discharged - recharged). If they are overcharged or
undercharged or left discharged, some for even just several days, they will rapidly develop sulfate. Even when a battery is stored fully charged, sulfate will form unless a desulfating battery charger is used. Using or storing batteries in temperatures above 75°F accelerates the rate of self-discharge and increases battery sulfation dramatically. In fact, the discharge rate doubles, as does sulfation, for every 10°F rise above room temperature.
Polaris Buys batteries in bulk, and we have no idea they have sitting in a discharged state.
This means the batteries probably are
pretty sulfated buy the time they get put in the bike. The dealer charges them, but this doesn’t fix or help the battery much after sulfation has occurred. And these batteries sit sulfating in bikes on the showroom floor.
The new owner rides home and 2 days later the battery is dead. No, it’s not the parasitic draw on the bike, it’s the battery. Its because the battery was poorly maintained
Some things to consider:
Our bikes use AGM batteries: These batteries sit at a higher voltage (12.8 - 13 volts) and need to be charged at 14.4 to 14.8 volts.
Car and truck battery chargers and tenders, etc. Use a lower voltage (12.6 volts)
When a non-AGM battery charger is used it will under charge the battery and give a false indication that it is good.
And bam Sulfation rears its ugly head.
When you get your new bike home, put it on a battery tender maintainer, that also has a
disulfate mode and its
AGM one. Yes, they are more expensive. 100 - 130. But that’s what a battery costs.
When I brought my new bike home. The de-sulfating until went through three times to finally disulfate the battery.
I have done this with every motorcycle battery I have owned and got 4-5 years out of them.
Polaris doesn’t tell you to use a tender because of draw. It's because of sulfation.
If batteries were shipped dry and acid was added, and the battery was fully charged. Battery threads would be rare.
