Frequently Asked Questions
What makes Shorai batteries different?
A: They contain Shorai-proprietary eXtreme-Rate Lithium Iron prismatic cells (chemistry LiFEPO4). They contain no poisonous lead, no dangerous acid, and do not create explosive gases during charge, as traditional Lead-Acid batteries do. Compared to traditional batteries, Shorai lithium batteries are extremely light, have a much lower self-discharge rate, do not sulfate, and are environmentally friendly.
Can I use Lead-Acid battery chargers or charger/tenders?
A: Yes. However, you may not use a charger/tender if it has an automatic desulfation mode, which cannot be turned off. We have confirmed with Deltran, makers of the Battery Tender brand, that their products do not have a desulfation mode and are therefore okay for use with Shorai batteries.
Can the Shorai LFM18A1-BS12 be mounted in any position?
A: Yes. There are no liquids in these batteries.
What's the difference between the "equivalent" and "Actual" Ah capacity?
A: The manufacturer includes the "equivalent" (PbEq, "lead equivalent") rating to show a more apples-to-apples comparison between the lithium chemistry and the lead-acid battery that you're likely replacing.
How does the Shorai LFM18A1-BS12 perform in cold weather?
A: This battery performs well in cold temperatures, but it may need a quick warm-up for best results. Turning on your headlights or another accessory for 30 seconds to a few minutes, depending on how cold it is, helps improve the starting power. Ensuring that the battery is fully charged will also help with first-start performance in cold weather.
Cross Reference & Compatibility
Customer Reviews
Needed a new battery and figure would give this one a try. Installed on my 2017 hayabusa and so far no issues with it.
Fit perfectly
Great fit and plenty of power to start my 2007 Ducati Monster S2R1000. I'm hopeful that the battery will have a long service life, given that it is solid state.
I've used Shorai batteries for some. time. I have a 1960 H.D. panhead and many years ago made my own oil tank.
I a have a 6 inch width and this battery has plenty of room.
Also carries quite a punch. (270 CCA) I designed a kick assist starter and easily starts the bike.

The battery was easy to order, a fair price, adequate shipping time and packaging was excellent. It was a tight fit in my R6 but, it did fit well. After 3 weeks it is still operating correctly.
Fabulous batteries. This is my 2nd & I'm pretty sure the 1st died, after many years, from neglect. I've a '00 VFR & AGM batteries lasted months before cooking dead in the Phoenix heat in a very hot compartment w/ a high charge rate. The Shorai Li-Fe battery lasted for Years (like maybe 7-ish) before giving up & likely from not keeping it charged for the last couple when I'd quite riding (lots to none). The new one is like the 1st; Fabulous product (let me say again FABULOUS product) presented w/ perfect detail for a great install (down to the foam pads on the nuts to keep them in place while connecting the cables) w/ great support & thoughtful implementation at every turn. You're a Class Act Shorai!
Yup, you're going to pay for that experience - Twice the cost for at least 7 times the battery (factor in the way better performance on top of longevity & that doubles).
I've used a bunch of these in motorcycles and power equipment and have never bee disappointed.
