Big upgrade in starting
I replaced the stock lead acid battery with in hopes the bike would turn over quicker and I'm very impressed. The bike fires up almost immediately, huge difference! The weight savings is nice too but the empty box comments is quite an exaggeration IMO.

5 yrs.Time for a new one
It worked in my 09 WR450 for supermoto duty and my Beta 300RR for 5 years so I'd say it's a good battery. I swapped back and forth because I'm cheap like that and I can only ride one at a time.

Shorai Lithium-ion Battery
I have been using these on both street and dirt bikes and had good luck. The funny thing is that sometimes when it is cold outside it is best to turn the bike on with lights and a load before trying to start so the battery will start to warm up and release more of the storage for starting.

Does this require a special charger?
JOHN N on Sep 28, 2016
BEST ANSWER: No special charger is required, however, DO NOT use a charger if it has an automatic "desulfation mode" which cannot be turned off. Shorai offers a dedicated charger/store device that you can purchase if you wish.

Will this work any better than the stock KTM lithium battery? I have 2016 XCF 350 and the stock battery struggles to start the bike when the temperature outside is below 60 degrees or so.
Vladimir C on Dec 20, 2016
BEST ANSWER: I haven't experienced the performance of the stock KTM Li-Ion battery...my 2013 KTM EXC-350F came with a lead acid battery which needed regular charging and quickly lost cranking power. I can say thought that I've been very happy with the Shorai Li-Ion battery, which has started my bike easily at temps down to 45F without running out of cranking power. I also love that the battery has not yet needed charging...sometimes I'll go a month or two without running the bike and the battery still cranks like a new one every time.
How many cranking amps?
cam c on Aug 18, 2016
BEST ANSWER: That would depend on the battery's application. As an example/ballpark a CanAm Outlander 1000 with battery model lfx27l3-bs12 would have 405 cold cranking amps claimed by the manufacturer.

Let us know if you have a specific model or machine in mind.
Part number 1333530005 what side is the negative terminal on?
A shopper on Nov 17, 2018
BEST ANSWER: Looking at the picture... the negative terminal is on the left side. You can see the black and red circles on top of the battery, black is negative. You might be able to turn the battery around during install if your cables are long enough.
will the battery tender plus 1.25 amp charger work on Shorai Lithium Iron battery?

Shorai Lithium-Iron Battery
DelTran Battery Tender 1.25 Amp Selectable Charger
DelTran Battery Tender 1.25 Amp Selectable Charger
BEST ANSWER: No. The Shorai battery has its own dedicated charger. The Battry Tender is designed to work with lead acid and AGM batteries while the Shorai is a Lithium Iton battery. Also, you may void any warranty if you use anything but the Shorai charger. With that said, this is a great battery. I’ve been using it for two years and it’s been great. After putting it in, I never charged it for the first nine months or so, with only riding a few times in that period, and I only charged it at that point because I was going on a long ride and wanted to make sure I had a full charge.
Does this have a battery mangement system to keep it from totally discharging which will ruin a lithum battery?
Robert R on May 2, 2019
BEST ANSWER: Not built into the battery that I'm aware of. I bought the charger/maintainer and kept it connected whenever I had my DRZ 400S in the garage for an extended period of time. My last trip of 250 miles I stopped about 15 miles before the end and the bike didn't have enough power to start it. No kick start on this bike. I managed to push it and jumped on to get it started. Since then the battery will not charge with the Charger/maintainer. I am taking the bike into the Suzuki shop this week to see if the alternator is at fault or the battery.
Are the connectors on the battery exactly like the ones in the picture above or are they more standard connectors?
A shopper on Mar 24, 2019
BEST ANSWER: Mine are just like in the picture.
What are the dimensions of the battery?i
Eric Z on Nov 20, 2016
BEST ANSWER: We would have no way of knowing which battery you are needing. If you could give us your make and model of your machine we could find a battery that may fit.

Hi, does the battery comes charged?
Also can you ship it via auSPS or UPS, not fedex?
Gustavo R on Dec 29, 2018
BEST ANSWER: The battery will come with some charge to it but we do suggest that you fully charge it before using it. Unfortunately, UPS is not one of our carriers and we are also unable to select a specific carrier. I apologize for the inconvenience.
