EarthX ETX36C Eco-Friendly Lithium Motorcycle Battery with Built-in Battery Management System

Motorcycle - KTM 1190 Adventure. Purchased this Earthx battery over 5 years ago and it's still going strong. Ridden to Alaska, bike started well on 32F days. Have stored bike for 5 months at a time - voltage going into storage - 13.2, out of storage - 13.0. I own 20 motorcycles and have tried almost every brand and construction of battery. This Earthx has been the most consistent and reliable. Downside...yes it's a big one...this is an expensive purchase and getting more so (I paid $300 back then). I believe it's been a good value though after 5 plus years.

This is a fantastic battery that I used in motorcycle for several months. I had an issue with a subtle draw from my bike that killed the battery when it was not in use for 3 months. Their customer service was excellent and sent me a brand new battery right away. They even sent me a diagnostic of the old battery and their suggested charger. The new battery has worked perfectly for many months now.

Bought for a bike that I ride infrequently about 3-4 months ago. Has been sitting for the last 4 weeks. Try to start it today and nothing. I get 1-1.3 volts on the meter. Won’t take a charge from either a charger or battery. Complete and total waste of money considering I spent double what I would have for lead acid specifically for the supposed long term storage capability. And like everything else these days, I am unable to return now. I really wish there was a zero star option.

Fantastic design! Less than half the weight, installed in my R1200GS in minutes, and fired right up. I'm a fan.

I know it's not cheap, but this battery had a huge effect on my motorbike experience. I have a 1200 Yamaha super ten. During its first 6 years, it was trucked to the dealer 3 times because it wouldn't start and flooded, failed to start around 50 times (seriously), went through an AGM battery every 12 months, and entertained the brothers many times on cold, damp mornings. After many attempts to sort out the problem (the dealer gave up), I fitted this battery, and ever since (no exception) I have had no problem starting at all (first time every time) for 4 years or so.

This battery, though pricy, has been great so far. I installed it in my 2016 KTM Adventure a few months ago. Honestly, my stock battery was great too, until it wasn't. It did shave some weight off, which was far easier than diet and exercise. Time will tell, but so far... I love it. Cranks right up!

Does the job I have tried for years to get a battery to do. Cranks my VL1500 Suzuki intruder fast enough in cool weather to start. I tried many heavy duty batteries with no satisfaction until I got this battery. Suzuki Intruder would not turn over fast enough to start below 50 degrees. Now it spins like a top.

top item,stock battery with extras attached only just turn over,always thinking wont start,but this battery,has no problem,have replaced one as it lasted two years only with the same item,for some reason,batteries don't last long in the Philippines,maybe humidity

Excellent battery, started high compression v-twin easily. Compact size, will fit almost anything.
