BOSCH BLP5S - Group 5-12V Lithium Battery - Powersport Li-ion Phosphate - 120A for Motorcycles, ATV/UTV, Snow Mobiles, Personal Watercrafts, Scooters and Jet Skis - 4.45″ x 2.72″ x 3.35″

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.

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.

Battery worked for a short while, but it cannot be recharged. I've used a lithium Noco charger as well as the Bosch branded charger. Both will show that it's 100% charged after a few hours, but then the battery shortly drops to low after being off the charger. This thing was a waste of money, buy something else.

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.

Purchased to replace my old Harley Battery. It's nearly 14lbs lighter than OE battery, however it's not a direct fit. It requires that you bend the factory battery connectors. However, for me, the weight savings is worth it. The bike cranks over perfectly, and quick! Now we'll see how long it lasts...

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.

Works great on my 21 Road glide
