Battery

Greetings All,

I went out to go for a ride this morning and the motor did not want to crank with it's usual "gusto". I keep it on a smart charger/tender so it is not like I let it sit and discharge on its own.
I switched it over to a different charger and then tested it. Resting voltage was 12.8 volts. Turned on the ign. key and watched the volts drop within 5 seconds to 11.5v and still falling. So clearly I need a battery.
It irritates me that the battery is already bad on a 2012 bike. I have never experienced a battery with such a short life.
Getting to the meat of this topic is which replacement should I invest in. Opinions please...
Shorai, worth the money? I do want more available cranking amps. When I spoke to the Shorai people I felt like I was getting wind blown up my skirt.
Yuasa?
Any other brand?
I do know I will want a AGM battery if I don't go with Shorai.
And what is the real correct part number? I see YTX12BS and YTX14BS as both being the correct part number.

Thanks in advance.

I don't mind the going and I don't mind the stopping. I absolutely hate the stop and going.

I have a small case Shorai and it's awesome! Going on 3 years. $140 bucks though from Chaparral.

Before you buy a battery have a look at this.

Did the load test. I also have access to a digital battery tester. I don't trust it because Interstate wants to sell batteries but it does provide a reference number I can use to compare. Bike needs a battery. i am just looking for comments on Shorai primarily.

Bought a Shorai for my daughter's scooter (Genuine Buddy 150) about a year ago. Battery is unbelievably light compared to lead acid. Twice the cranking amps and the scooter starts like a champ when it's warm/hot outside. I'd read somewhere that lithium batteries lose a bit of their cold start capabilities in colder weather and her experiences last winter seem to bear that out. Still, the battery has been awesome and I'll buy one for my Glee when the OEM wears out.

one thing to watch out for with lithium batteries... when they go dead they go DEAD. a lead acid battery might have enough juice left over to bump start the bike or something if you run it down but the voltage drop off on Li batteries is real steep.

Thanks for the responses. Still debating the expense of a Shorai. I will need to sacrifice the funds I had put away for a peg lowering kit. One added question is the durability with rough roads. I do use this bike on fire roads. Wondering if I might shake the plates loose.

Your experience with the OEM battery is rare. Problems with higher capacity Li batteries are fairly rare, but the failure mode is much worse (Boeing, Tesla, Chevy Volt, etc.). I'm not sure I want a Lithium battery right next to my ECU. My experience with battery life is flooded= 2-3 years, AGM (maintenance-free) 3-5 years.

The Shorai is fairly new, expensive, and long-term reliability is unproven in my mind- especially on a V-twin without balancers. The battery is also complicated, needing precise DC charging voltage control. There have been early failures reported. Lithium batteries also do not like to operate in cold temperatures.

On the plus side, the Shorai is lighter and smaller, so if you need room to pack in terminal buses or wiring, it might be the ticket. Also, Shorai's warranty / customer service support is second to none.

Not all charging systems work well with the lithium batteries and as others have noted they give no warning when they are going bad. So you will want to do your homework.

One thing you might want to check is your battery tender. I had one that in effect was overcharging the battery and I never knew it until the battery started to cause issues. The battery in question only lasted 2 yrs.

Battery tenders if working properly should show an initial high voltage charge say up to 14.5 volts when you first connect them to a good charged battery, but then should drop down to the 13 volt range and keep that level of charge. The better ones will cycle on and off.

Shorai battery is NOT the same as the one used in Boeing and neither is the operating requirement the same. Shorai battery is NOT the same as the lithium batteries used in your phone batteries either - you can argue its a bit deceptive they used the word lithium.

They are unbelievably light. Don't need special charger, just one without the desulfercation mode... Basically most cheap chargers. Yes they won't wake up from a deep discharged state but I don't think most mc batteries can either.

Starting from extreme cold ( freezing point or below)in the morning might be an issue.... Just leave your lights on for 30 seconds to "excite" the batttery and try again. I never experience this issue because my bike is stored in place warmer than 0 c
