BLP14 - Group 14-12V Lithium Battery - Powersport Li-ion Phosphate - 120A for Motorcycles, ATV/UTV, Snow Mobiles, Personal Watercrafts, Scooters and Jet Skis - 5.91″ x 3.43″ x 5.63″

We installed this into our Can-Am spyder, the starter runs faster. This battery is smaller and lighter than a wet or gel cell, unit comes with base spacers to allow installation. No issues after several months of use.

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.

So I purchased this a few months back and even the first time I installed it, the starting was weak. I connected it to the tender overnight again the following days to make sure that wasn't the issue and even replaced the Stator. Due to an accident in november 2025 my bike had been pretty much parked until february this year, but I kept connecting the battery tender frequently to prevent battery from draining, even though these batteries are supposed to habe built in protections for that. This month as I'm finishing some repairs, to my surprise the battery even when fully charged with a proper battery tender in a day, it is fully drained the next day and there are no short circuits in my Harley or anything, this was even tested with the batter completely removed from the bike. I went against some friends recommendations with other brands, because well, I couldn't go wrong with BOSCH......huge mistake!

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

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.

This battery mounted right into my 2016 Harley Davidson ultra glide ultra Limited without any issues the bike fires right up no problem even on the coldest mornings I’ve tested it down to 30°. I do keep my bike on a trickle charger all the time, but I would do that with a normal battery anyway so I can’t say anything about it adding or taking away from the performance of the battery I did have to make a slight adjustment to the mounting tabs just bending them out a tad bit it was not a problem. There was no danger of them breaking as long as you do it carefully and once it’s mounted in there, it’s fine. I didn’t weigh the old battery and I didn’t weigh this new battery, but it is probably a quarter of the weight of the regular battery I had in there before.

I bought the Bosch BLP14 battery for my Ibex 450 motorcycle, primarily for the weight savings. It arrived in good shape with the indicated multitude of spacers, and the terminal bolts and nuts. As usual I had to put little pads under the nuts to locate them in place and raise them up to where the bolts would easily engage them - why we still have to do this after decades of this poor design I don't know. Otherwise, it went in easily and the bike started and runs fine. Time will tell how it holds up, but I suspect this battery from a company like Bosch should do well. Now, regarding the battery dimensions. The Amazon description for this BLP14 variously shows it as "3.43"D x 5.91"W x 5.63"H" and "3.43"D x 5.91"W x 3.63"H". The Bosch website was no help on this mystery, but I suspected it was the smaller height for this Class 14 battery. I measured it and in fact the actual height is 3.63" so it should fit as a replacement for batteries such as a Yuasa YTZ14-BS. The 5.63" measurement would reflect the use of some of the included spacers to raise the battery height, if needed. Hope that helps!
