Wanting a light weight battery and only wanting the best available parts for my bike, I chose to go with an EarthX lithium 1.3 pound battery. After lots of research, I chose EarthX and I couldn't be happier with my decision.
EarthX has some superb reviews on the net, but I could not find anything on this forum about them. Though despite not having any reviews or mention in the s1000rr platform, I still felt it was my best option. Not just because it was the lightest battery, but due to the lack of required service. There are no trickle chargers needed. Simply plop it in and forget about it. The only thing you would be losing is 6.80lbs.
We'll after being on the EarthX fence for a few weeks, I decided to go forward with the purchase last week. I purchased an ETX12B on ebay through RaceCrafters. RaceCrafters had the battery listed as: "Fits S1000rr" which was just enough comfort for me take the plunge
. RaceCrafters was a pleasure to deal with. I got the battery for 169 including free shipping. Not only that, but the free shipping was 2nd day priority. I send them payment, two days later there was a nice little box at my house. I wish all my transactions were so fluid. It reminds me to leave them some feedback.
The Battery (ETX12B)
The battery came packaged in a nice little white box. Inside the box was the battery (thank God), several strips of adhesive backed foam and an EarthX sticker. The battery was super light and I was pleased with the overall quality and feel.
Let me start by saying that I am not affiliated with either EarthX or RaceCrafters. That being said, I am thoroughly impressed with the battery. I honestly can feel the difference just rocking the bike left to right. The bike started up faster than the stock battery too. I will continue an extended review of the battery, but the only difference from the OEM battery that I can tell other than weight is it starts up faster. I have heated grips and BMW does not recommend using them during stop and go traffic, as the alternator does not provide enough juice, so it sucks from the battery. That being the case, I turned the grips to full blast and let the bike idle for 10minutes. I turned the bike off, than cranked it back up. Unfazed! Started right up like a champ! I wrote this review for two reasons, one is to let you guys know how the ETX12B works with our bikes, the other is to show appreciation to EarthX for providing a wonderful product.
With taking pictures and going at snail speed, it took me around 20-25 minutes. If I had to do it again under stopwatch, I could honestly install it in under 5 minutes. So for some of you that dont wrench at all, no worries. Its as easy as my ex-wife. Below are the steps I took. Enjoy:
1.3 pounds of littleness
1. With the provided foam. Adhere two of the thick pieces at each side of the battery. Cut one of the thick pieces, splitting it down the length so you have two narrowed thick pieces. Attached the the split pieces to the front labeled side of the battery. The split foam pieces interact with the rear battery tray corner angles for a solid fit.
2. Get one of the thin pieces of foam, and adhere it to the non labeled side of the battery as shown. Be sure not to adheare it too low on the battery face as it will interfere with the battery tray. Bottom of the foam should be right over an inch from the bottom of the battery.
3. Remove old battery (Negative terminal first) and install the new EarthX. As you can see, it fits like a glove. I am very pleased with the fitment.
