My FLHT has the stock radio system in it, so there's an added powerdraw, but I have replaced every other light in there (except passing lamps) with LED's, saving me gobs of wattage (22 marker/gauge lights @ 5w each + Brake Light @10w + Headlight at 55w with 5w marker light) for a total savings of 180W (or between 12 and 15 amps off the stock 32 amp charging system). Only reason I didn't go with the bigger recommended battery is because I'm not drawing anywhere near what a completely stock bike would draw.

Good starting power out of the box.

Incredible starting (quicker than with AGM).

Lightweight at only 1.9 lbs vs HD AGM at 17.7 lbs.

CCA is 70 over a stock Harley AGM.

13.8v charging power from the bike means it will live at or near 60-80% charge it's entire life (but the battery doesn't mind it and it doesn't shorten battery life).

Have to pay attention to overvolt charging, don't go above 15.0v or you will damage the cells and shorten the life of the battery if you use an SLA charger.

No balance charging port.

Perfect fit in my old 76 Bonneville and it's always charged.

Can't think of any.

I used other (AGM type) Scorpion batteries and they did not pass my approval; they only last about 2 years max for me on both my bikes. I had a slow crank problem on my old Yamaha, and was looking for a higher CCA, this looked good to me, and it is. I am watching for length of use on this battery too, since it is a Scorpion, and after 1 year it is still good. We will see how long it lasts, but my Yamaha spins right over now, every day. I am very pleased.

very strong, fast crank - that was the selling point to me, and I am pleased with it.

Maintenance free.

After 1 year, still going strong. It was worth the extra cost to me to know that my bike will start every day.

***Note From BatteryStuff.com****

Manufacturer is producing two part numbers for the same battery. Battery can arrive as an SSB12Q-FP or an SSTX12Q-FP. Both part numbers reflect the same battery.

Having both the Scorpion Stinger and the Shorai LifePO4 Lithium Iron Phosphate - the Shorai held up better. I didn't start having starting delays until a couple years in (and post-when the weather was in the teens for a week.) After that the Shorai started being slow starting up but the Scorpion was that way out of the box.

Since I don't own a car, and only ride, I may even switch back to the AGM battery. at 9lb is less weight than the stock battery but it will be more reliable in colder weather.

Love the weight savings. On the BMW F650GS (2006) the battery compartment is up high, where a motorcycle gas tank normally sits. The reduced weight up high improves handling and off-roading.

I live in the Pacific Northwest. When they say these battery types don't like cold weather - they even mean low 50' or 40's. I ride year round and this is pretty common in Oct., Nov, Dec. and throughout the winter. The bike won't start quickly - you have to let it sit with the lights/electronics on for a few minutes, try starting, let it sit some more...

This is my second purchase of this battery. I just replaced my first one - it was 4 years old and was still doing good....until I let it sit with the parking lights on (accidently) for 3 hours. Needless to say, that killed that battery. But, I was so satisfied with the first one, I always said when something happens to this battery I will replace it with the same thing in a heartbeat! I came right home and ordered another one. It has never failed to spin my starter quickly and get the bike running. I have a 30+ year old bike and the original type battery just wasn't cutting it anymore. I never knew if it would start or not, so I looked for a high cranking amp battery. This fits the bill, and does very well. I am well pleased and so have bought my second one. When my old Gold Wing needs a new battery I will look here too.

This is the second battery I purchased of this brand from Battery Stuff. I find the performance of Scorpion batteries are excellent.

Super light weight with plenty of starting power. Battery stuff is my go to source for motorcycle/atv batteries

Excellent customer service,

great Battery

It’s a very light battery, And packs a punch of cranking amps, durable long lasting And I would buy it again!

5 years, thats dependability.

Cant judge yet since winter has come. Arrived almost fully charged and took less than couple hours to attain 100%. Fired bike up with no problem . Now on Maintenance Charger till warmer weather
