Shorai's Lithium Iron batteries are the ultimate fusion of light weight and power technologies. The LFX36L3-BS12 battery weighs in at 4.96 pounds and offers 540 CCA. These batteries will require no change to your charging systems and are a drop-in replacement for your original battery (Included shims may be required for installation).
What makes Shorai batteries different? 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 much lower self-discharge rate, do not sulfate, and are environmentally friendly.
Can I use Lead-Acid battery chargers or charger/tenders?
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 OK for use with Shorai batteries.
Can Shorai LFX be mounted in any position?
Yes. There are no liquids in these batteries.
Remember to Install the Split Bar!
To meet shipping regulations, this Shorai battery is disconnected and inactive to allow it to be legally shipped via ground and air services. Thankfully, the procedure to 'activate' the battery is extremely simple, but can be easy to overlook.
The hardware you'll need is included in your box: A "series" bar about 1 7/16" in length, two M6 bolts and washers, four screws and a plastic cover. These pieces are bagged together in your box. The bar needs to be installed as shown to the left and torque the bolts to 75kg/cm (7.3nm, 68 inch/lb) before your battery can be used.
What's the difference between the "equivalent" and "Actual" amp hour capacity?
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.
The lead-acid capacity rating itself is based on a complete discharge at a low discharge rate. Under actual cranking conditions they will deliver considerably less than spec capacity. And because lead-acid batteries begin sulfating when only a small percentage of the capacity has been used, and their internal resistance rises as they are discharged, the actual capacity which can be used may be as little as 20% of the mfg. rating. Discharge in excess will not only damage the lead-acid battery, it may not allow proper starting as voltage sags.
For example, the Shorai LFX18 12V series have 6Ah cells internally. But, the cells are capable of 80% discharge without damage while still retaining more cranking power. As such, the usable capacity (or "reserve capacity") of an LFX18 12V battery is very close to 18Ah-rated lead acid batteries, while also providing superior cranking and huge weight reductions.
Cold Weather Performance Expectations
Down to about 20° Fahrenheit (-7°C) most users find that they can start normally on first crank. If your headlight comes on at key-ON, it is good for the batteries to flow some current before cranking in cold weather. The suggested headlight-on time before cranking depends on the temperature. If starting at 40°F/5°C, 30 seconds will help wake the battery and increase cranking performance. If at 0°F/-17°C, leave the lights on for 4~5 minutes before cranking. The result will be a better first crank, and longer battery life. If the engine fails to start on first crank, that first crank has warmed the battery, and the second attempt will be much stronger. Other accessories that can be turned on before cranking can also be used for this purpose, such as heated gear, radio, etc... Insuring that the battery is fully charged after storage also improves first-start performance in cold weather.
I received the battery the day after I ordered it. It is much lighter than my previous battery but seems to have a great deal of cranking power. It has started my bike without hesitation . I am very pleased with this product.
I purchased this battery for my 20014 HD - FLHTCCI - Ultra-Classic. This was my 4th battery purchase for this bike and my last HD battery just could not provide the cranking amps needed to turn over the nearly 11 year old starter. I also purchased the Shorai Battery Charger. I inadvertently bought the battery with the polarity reversed, thinking the listing was incorrect. This is the correct battery for the FLHTCUI. It turned out that with the smaller size of this lithium battery, the reversed terminals did not pose any hardship as there was plenty of room left over to route the factory cables. The Battery Mart staff were great and offered to reship the correct battery and stayed in touch with me to make certain that the installation went well. With the assorted foam spacers included in the packaging, custom fit and placement in the battery compartment was a breeze. This was particularly important to me due to the assorted "add-on" electrical accessories I have installed over the years. This battery requires charging "attending" when the MC is parked with the cables hooked-up due to security system and other drain on the parked bile and the Shorai charger is specifically intended for this purpose. The charger is placed in full charge mode before riding (15-20 minutes max.) and you get the most remarkable power at start-up. The instructions recommend that you "warm-up" the battery before starting with all lights and other circuits on before cranking (2-4 minutes). This, in fact, works best and is a small delay in "normal operations" but produces the greatest cranking power. No starter dragging these days and I have avoided the cost of a new starter.
This is one bad as battery with lots and lots of cranking power.
I run 10 1/2 to one comp. ratio. I have compretion releasees. I use them, but dont have to.
Wanted a light weight battery for my boat . Runs the jack plate , trim , starter ,etc . No problems in the three weeks since the install . Reminds me of the batteries in my rc helicopters . Just hope it never catches fire while charging (battery does not get hot while charging , so should be just fine). Winter storage will be removed from the boat . I think the price is rather high though , hoping
Easy way to reduce your car weigh by 30 lbs.
Starts & charges as well as the factory battery.
My quickest time at the track, a 12.39, with this battery.
No problem with lots of starting cycles, in the staging lanes,at the track.
Yes, it does weigh less than 5lbs.
Own a 1700cc bike that needs quite a bit of cranking power. Bought several gel batteries before that did not last long or did not have enough power left after cranking bike a few times. So far, this battery has been outstanding although pricey - but then nothing beats peace of mind to get started whatever needs to be started.
To the longevity of the battery it is too early to comment - just hope i
