    Will Y.

    5 star customer service!
  • I have been following this company for years now and I am constantly amazed at their ingenuity. I notice that their “competitors” try and copy them which is always a back door compliment.  Kuddos to you EarthX!

    Sam H.

    Innovative
  • I did a lot of research and found “cheaper” batteries out there but none that had the extensive manual or documentation to back up their “marketing” materials. I am very pleased with this product but also the company too as they are professional and seem to really care about their customers which is rare these […]

    Quality is never cheap
  • I finally replaced my chunk of lead years ago with an EarthX battery and the difference is incredible. My bike handles better and I never worry about it starting! I’ve had it 4 years now and couldn’t be happier.

  • Dear EarthX, I want to thank you for great service. You warranted my battery, and exchanged it for a new one. I want you to know that I thought I was in for a fight, not used to such good service. Very well appreciated.  Some times doing business online , especially second party , can be […]
    Beyond excellent customer service!
  • I have to admit that your customer service is well above the standard level that I’ve received from other aircraft businesses. I was expecting a “shrug of the shoulders” response regarding the limited two year warranty for a battery I purchased three years ago. What I was surprised to learn is that your company is […]

    Customer service well above standard!
  • When I called a real person picked up the phone when I had an issue with my battery. I then emailed your Warranty folks and everything was taken care of right away. I got a call right back, followed up by an email, with a replacement battery in the mail! That’s Customer Service! I will […]

    Great customer service!
  • Thanks a million for the “care package”.  It showed up this afternoon.  The 36C was exactly what my 1190R needed, starter spins up like it should now – I should have bought this battery 3 years ago when I first got the bike.  I appreciate your interest and help!

    Craig D

    I should have done this 3 years ago!
  • Dear EarthX,

    I have made 10 or 15 engine starts since installing the new EarthX battery last week. It is PHENOMENAL! It spins the engine over much faster and makes the engine starts much better.

    Gary W. (in an airshow performance plane)

    PHENOMENAL!
  • Thank you so much for the quick reply. You folks have the service side of this business down pat. I can’t tell you how much it means to me to have been able to sort this problem out so quickly and painlessly. In my years in business I graded my […]

    Customer for life!
  • My Aprilia Futura 1000cc V-twin doesn’t like batteries recommended by the factory and when using them it struggles to start and usually kills them within 2 years. It also likes to leave me stranded costing $400 for tow trucks and the embarrassment comes free of charge. One of my co-workers is using your batteries […]
    3 years later…..love my EarthX
  • OMG!!!  You sold me a battery for my RV-8A at the Northwest Aviation Conference in Puyallup, WA. I put it in my plane a few weeks ago but the weather did not co-operate until today. What a difference! My starter does not whine anymore and it cranks way faster! Also, I still have not lost […]

    OMG! You were right!
  • Recently purchased and installed an ETX680C for my experimental plane. The 680C replaced a Ballistics Performance EVO2 battery. Your battery is FANTASTIC. There is an amazing difference in cranking performance–I can almost taxi my aircraft when just running the starter!

    Ted W.

    FANTASTIC PRODUCT!
  • Questioned myself for buying such a costly battery, however it has been one of my best decisions. This battery has performed exceptionally well and I will continue to upgrade to these Lithium batteries on all of my sport equipment!

    Buck

  • The weight loss on my bike was felt immediately. Feels like a have a smaller bike now. Still can’t believe how light weight and strong starting ability. I’m thoroughly impressed. Hope it can hold out for the long run. Very happy so far. Install took a little TLC by bending some loop connectors but battery […]

  • By changing to this battery in my airplane, I shaved 10 lbs off the forward area and gave myself a far better battery. Easy fit too.

    Great weight saver in my aircraft!
  • Twice the CCA’s at less than 1/3 the weight. Great product and great company!

    Scott

    ETX36C
  • Purchased the ETX900 for my 3300 Jabaru aircraft engine in my Zenith CH750. The new battery spins the engine significantly faster, allowing for starting the engine without preheating every time (anytime it was below 60 degrees F) What a difference it made and saved me just over 10 pounds. It’s worth the price.

    Eric

    Zenith CH750
  • After flying all weekend I must say I am impressed with this battery (ETX 900). My Odyssey PC 925 always worked well until recently with 4 years of use it started turning the prop a bit slower each time during start.

    Your ETX 900 turned my engine and prop (IO-360, C/S) faster than I’ve ever seen […]
