Great service and fast shipping

The weight difference is incredible

The cranking power is better than any battery I have owned

The charge retention is awesome, no tender needed

cost to life expectancy is a bargainmiken

dimensions are not exact to oem battery so foam shim pads that are supplied are needed but easy to install.

I ALWAYS KNEW RESEARCH IS ALWAYS LOOKING FOR IMPROVEMENTS,AND NOW I AM COMFORTED BY THE LATEST BATTERY TECHNOLOGY,WOW! A DAY OF CELEBRATION FOR RESEARCH.

LIGHTER,SMALLER BATTERY IS ALWAYS BETTER,THAT HARDLY EVER REQUIRES CHARGING,WOW! LONG OVER DUE,SO NICE TO FINALLY SEE A BATTERY THAT IS SO MUCH BETTER,LIKE SEEING ONES BABY FINALLY GROWING UP.

AT PRESENT,THERE ARE NO CONS,ONLY WHEN NEWER TECHNOLOGY OVERSHADOWS THE LATEST AND GREATEST BATTERY,AND THAT WILL BE A LONG TIME FROM NOW.(PERIOD)

I will be ordering the charger maintainer in a couple of weeks.

First I am amazed at the order and delivery time.Ordered on sat and delivered on Tue.Very light and powerful I have a honda valkari(6cil) takes lots of power to crank on a cold morning, your batt spins it like a top!

needs more of the (thick) padding supplied.

I don't live in a cold place (Texas). I'm not worried about cold weather starting, but I will likely let the bike sit for extended time (maybe 4-8 weeks) next "winter." I do not plan to need any kind of battery tender.

Excellent replacement for my AGM battery. Very well packaged. Foam adhesive under battery nuts was a nice touch and made installation a breeze. Took me maybe 20 minutes to install, including unbuttoning and rebuttoning the plastics on the bike.

Added benefit. This battery is light weight. I can't really feel the difference in the bike's handling, but maybe a bike that's already lighter weight would feel the difference.

Delivery was way faster than I imagined. 2 days across half the country. Very, very good. Even though I ordered late in the day, it still shipped that day. I received it 2 days later. (Less than 48 later.) It even fit in my mailbox. (USPS shipped)

Battery comes (as they state) 70% charged. Quite understandable. However, the first few days the starting was just a little weak, though adequate. After running around for a few days the battery now is full power and starts strongly.

The OEM battery lasted over 60,000 miles and 7 years, and I replaced it with a conventional battery from Parts Unlimited. Thinking I made a good choice, that battery lasted only a year. Mostly because I wasn't riding the bike as I'd been in the last 7. Batteries typically must be used often to be appreciated. I'm now testing the Shorai, as I've ridden the bike, but will now let it sit a month to see what happens. Eventually I may even update my review

So I get 1000 characters to write this review, well let me start out with just 3. WOW That being said, I was pleasantly surprised how much grunt this battery put out even without precharging when I pressed the ignition switch on my 2003 Yamaha R1.

You're kidding me, right? No cons so far, let's see how it makes it through the next year at least.

Will never buy another lead acid motorcycle battery again. Not the cheapest battery you'll buy but well worth the peace of mind and performance.

When I received the battery in the mail I thought they sent me a display model by mistake because the thing weighs next to nothing. Hooked it up to the KTM Adventure and it turned that twin cylinder over better than ever. Incredibly lightweight and powerful with little to no discharge from non use. Comes with nice self adhesive backed closed cell foam sheets to take up the gap in the battery box for the smaller size. Best price, no sales tax and free shipping.

Nothing negative to say about this product.

Followed Manufacturer recommendation for my Suzuki DL650 a little too late, which was 1 model stronger than BatteryStuff website advice. Exchange was easy/fast with free shipment = Excellent customer service experience.

I have been commuting every day with it since 2 month (only)... Rain or Shine. I do not stop riding in NYC winter. So it's not exactly a "just bought" review, but quite almost. I bought the Shorai charger to monitor properly the battery = smooth and automatized, plug and forget. Did it once only since initial charge.

I don't have too many farkles (GPS, Volt/amp/temp meter, Gipro gear indicator) but I do manually switch all off overnight. I will stop doing it and see if it produces any longer time effects.

Next question is how this battery will sustain New York city winter, with the motorcycle sleeping (well covered) outside in the street? I do ride when in the 20F and not snowing.

Ride far and back home safely!

Light, Little and powerful,

Provided Foam Cuts & fits the gaps nicely,

Absolutely No cranking hesitation, with or without double headlights on.

Pricey investment, moreover if bought with its Shorai specific charger (which I did to feel on the safe side).

Never let it discharge too low (minimum monitoring is mandatory) to avoid damage.
