Tykool comes through again. Very impressed. I own another Tykool LiFePO4 battery for my vintage motorcycle. I have been very happy with that one since owning. So when I was shopping for a replacement battery for my older garden tractor, and I found this Tykool battery, it was an easy decision. This battery did not disappoint. It is an exact fit, high quality replacement for my John Deere garden tractor. Tykool LiFePO4 batteries are so much easier to maintain, last longer, provide better starting amps, and are way better in all aspects than conventional batteries. The integrated BMS continuously monitors this batteries performance and operating safety, so I have peace of mind. I really like how the battery is so light in weight. I am also impressed with how solid and thick the plastic case is. This battery has strong stainless steel battery cable mounting lugs molded into the case with cable mounting holes that are large enough fit my older garden tractor cables and bolts (7/16"). The battery arrived fully charged and once it was installed, my garden tractor fired up like I had two batteries in it. This was my first start of the season as my garden tractor has sat for months in winter storage. Nice! Another noteworthy added feature is the charge capacity and the voltage display integrated into the battery case. At the push of a button, I can tell the status of this battery. What a great feature and is a real time saver. No need to pull out a voltage meter when troubleshooting. I really like this battery. I really satisfied with the Tykool brand. Tykool means quality and goes the extra mile to provide excellent customer service. They also include detailed instructions and user information guides in the package. This valuable information provides you with all the care and use information you need to get the best out of your LiFePO4 battery. Very happy and highly recommend. If you want a light in weight, high cranking amps, fast starting, great performing, low maintenance battery, this is the one.

This is my 5th Tykool battery. I purchased 4 of them last year and I have been very pleased with them. I did however have one that only lasted a month or so. It made a loud pop and smoke came out. I contacted Tykool via email and they responded the next day. They wanted me to take a photo of the label on the side where the production run number is located. I sent them the photo and the next day I received an email telling me that they were currently out of those batteries. So, they were replacing it with the next higher grade battery. Three days later, it arrived and I just cannot express how good I felt with their customer service. The batteries are pretty cool as well. I now own 5 of them, one different model for my Goldwing. I just can't imagine going back to those old lead acid batteries. Besides being much lighter, the voltage doesn't droop, it stays nearly full voltage as long as there is life in the battery. Pound for pound, much lighter and more powerful. You will be happy with the Tykoll battery and if you do have any issues, customer service is top notch.

Unbelievably lightweight powerhouse of a battery! I can't get over how light this thing is, but I suppose not using lead in a battery can do that. It comes with instructions and warnings letting you know that you shouldn't hook this up to an engine that doesn't use a power regulator or get ready for a bad lithium story with fireworks. There is an LCD screen on the battery to show how charged it is. 400 cold cranking amps in a lawn mower battery is premium, if taken care of it should last 2500+ cycles. Definitely worth the money.

High quality lithium battery with lots of starting power and super fast charging. I love the battery voltage monitor right on top, so you can quickly assess the health of the battery without having to go grab a multimeter. Super lightweight compared to typical lead-acid batteries...it feels like a joke, but it works like a champ! It isn't inexpensive, but I've purchase motorcycle batteries from this brand before and they have all been great quality and last for years. So, I'm willing to pay a little extra to have the peace of mind that this battery will last many years with no maintenance. I recommend the Tykool 400CCA lithium battery, if you'll be needing one for your lawnmower, atv, utv...etc.

I ordered this Lithium based battery for regular use in my Craftsman L240 mower. It’s the right size and it features over 33% more cold cranking amps. Very helpful when using it to haul a cart of firewood during a cold winter. It has the reliability of LiFePO4 cells with a 8 Amp Hour, 400 CCH capacity. The digital meter offers instant battery related data charge and use. It’s an excellent choice given its reliability, increased CCH, and reasonable price.

New battery, new season, old gas. I beat on this new battery. Cranked like a champ for way longer than it should. Spun just as strong as the 100% charge it was delivered with until I finally got it running. Never seen this kind of performance from lead acid.
