BOSCH BLP30L - Group 30-12V Lithium Battery - Powersport Li-ion Phosphate - 120A for Motorcycles, ATV/UTV, Snow Mobiles, Personal Watercrafts, Scooters and Jet Skis - 6.89″ x 3.43″ x 6.10″

I bought this Bosch Lithium Battery BLP-14Battery for my 2013 Aprilia Tuono 1000 V4 engine. I replaced my 2-year-old Energizer AGM Battery was giving me a hard time starting after Refueling. I read many reviews where people were saying Lithium Battery turns the engine over faster. I also notice the same thing. My Aprilia V4 never started so fast before, and I have had this bike for over 2 years now. This battery seems to be 25% of the traditional battery weight. I only had this battery in my bike for one week now. Time will tell how long it will last, so far I am very happy with it. We don't have to worry about cold Lithium start as i live in South Florida. Our summer is 100°F and Winter is 60°F if it's a cold day. Don't forget to buy Lithim Compatible Battery Tender Non Non-Lithium Battery Tender will ruin your battery. I did a lot of Research and didn't know what to expect, but i am glad i bought this battery.

Seems to be good replacement battery. Used to replace a "heavy" AGM battery in my CanAm Spyder. Fits great after using the adapting spacers. Appears to be a good value. Seems to crank the engine right over, starting easily.

I don't impress really easy, but I am impressed with this lithium battery. I used it to replace the stock lead/acid battery in my Teryx 800 SxS. Living in Southern Arizona presents challenges with batteries and L/A batteries don't seem to take to the heat well (especially non-serviceable sealed L/A batteries). PROS - Weight (Fraction of what a L/A weighs), Fitment (Even though it is by nature smaller, it is in a case with spacers to adjust to your stock battery holder), Durability (TBD, but so far has already outperformed the L/A). CONS - Just a bit more expensive but anticipate a much longer life.

Installed in a friends BMW 800 and works well ,will sit out at night, always cranks , even better as it it like 13.2 volts so cranks fast

You have to make this battery fit in your motorcycle. It is much smaller and lighter than your original battery, and it comes with lego-like blocks to help it fit in your battery box. Wouldn't work in my bike, even though the battery was cataloged as the correct model. These lithium batteries are light and they are small, but they are not plug 'n' play. I returned mine to Whole Foods and bought a normal maintenance-free battery.

This BLP14 is a step beyond the level required for my bike; the BLP9 is sufficient according to the Bosch match for my bike's Yuasa battery. However it is still radically lighter, saving about four pounds by switching. Between the price being about the same as buying a lead battery and the weight and performance, I highly recommend this unit. One nit you should be aware of: the battery terminals do not hold the rectangular M8 nut semi-captive the way the Yuasa terminals do. So I recommend care and either a small rubber band or some electrical tape to avoid losing the nut during installation.

Cranks the motor better than stock. Much lighter than stock battery and notice it during daily driving. Ingenious mounting blocks that make the battery fit perfectly. So far, so good.

seems to work great, plenty of power to start my snowmobile!
