  • Perfect FitMeasuring 8.14*6.88*7.5 in(L*W*H), Polarity:[- +], Weight:12.8 lbs, Voltage: 12.8V, Cold Cranking Ampere:600A. Make sure to measure your old battery and compare the dimensions with TPE battery to ensure it fits your vehicle
  • Outstanding Performance and LongevityAutomotive lithium batteries in BCI Group 26 stand out with their exceptional performance and longevity. They utilize advanced lithium compounds as electrode materials, offering high energy density and extended cycle life. Under normal usage conditions, their cycle count can reach several thousand, far surpassing traditional lead-acid batteries, providing consistent power for your vehicle
  • Superior Safety Performance, Worry-Free DrivingLiFePO4 lithium-ion automotive batteries are made with safe and stable lithium iron phosphate material. Equipped with a BMS (Battery Management System) control circuit, they provide significantly enhanced safety performance compared to ordinary lead-acid batteries. They support complex vehicle electronic systems with high power demands, including start/stop functions, ensuring a carefree driving experience.
  • Comprehensive LiFePO4 Performance Upgrades, Lightweight and DurableLiFePO4 batteries are not only lightweight and durable but also feature efficient charging and discharging performance, making them ideal for replacing or upgrading automotive batteries. Adopting LiFePO4 batteries can reduce fuel consumption by up to 20%. Additionally, they come with built-in smart protection circuits to prevent overcharging, over-discharging, and overcurrent, eliminating the need for regular maintenance and addressing long-term inactivity issues
  • Emergency Switch Design for Sudden SituationsWhen the battery experiences abnormal discharge leading to low power, the protection board detects the low power level (30%) and activates a three-minute warning (intermittent power failure reminder). After three minutes, the battery enters protection mode. By pressing the emergency switch (silver button), the battery can be used normally for 10 minutes to address sudden situations. If accidentally pressed and locked, pressing it again will unlock it, providing convenience and ease of use.
  • Premium Customer Service, Always at Your ServiceWe offer 24/7 rapid-response online customer service and support, dedicated to ensuring your satisfaction. We welcome product inquiries via email and promise to make your shopping experience delightful and hassle-free

Description

Verify the minimum Cold Cranking Amps (CCA) required by your vehicle and never use a battery with a lower CCA rating than recommended. 3.Must be used to charge the charger specially equipped or recognized, otherwise it may shorten the battery life or battery failure. 4.When charging, please place the charger and battery in an open and safe place that is ventilated, stable, dry, free of inflammable and explosive materials and out of reach of children. 5. If you don't know your battery's model, provide us with your car's year, maker, model, configuration, and displacement, and we'll help you select the right battery. Lithium batteries are up to 70% lighter, charge faster, last 3–5 times longer, and provide more consistent power. They’re also maintenance-free and more eco-friendly than lead-acid batteries Yes. Our lithium batteries are designed as direct drop-in replacements for standard lead-acid batteries with the same group size (e.g., G48, G27). Please confirm the size and terminal orientation before ordering Lithium batteries have a very low self-discharge rate. If unused, we recommend disconnecting the battery or charging it every 3–6 months to keep it in optimal condition No. Our lithium batteries are designed to be fully compatible with standard automotive charging systems. Just make sure your alternator outputs between 13.8V–14.6V, which is normal for most vehicles

  • Great for Fuel Efficiency
Style: Group26 Buttons
Switched to LiFePO4 and noticed a reduction in fuel consumption. This upgrade has paid off.

  • 2020 Chevy Bolt: So Far, So Good
Style: Group26 Buttons
Even though the Chevy Bolt technically is supposed to take the 140R / H4 / LN1 battery size, the Group 26 is pretty much exactly the same size, so I took a chance on this battery. Luckily, the battery fits in there almost perfectly. The battery was delivered with high SoC (~90% 13.3v), which I know many are concerned about. The battery fits in the existing retention slot perfectly, including the clip in the bottom that keeps it from sliding back to front (see photo). The only thing that doesn't fit perfectly is the retention clamp over the top goes right over the top of the reset button unfortunately (see photo), which I don't believe has anything to do with it being Group 26. The location they put the reset button isn't good; they should have located it more in the corner of the battery instead of dead center. The battery button to check the voltage and battery percentage is handy, but it's very difficult to use. I'm not sure if I got one with a bad button or if the internal circuit board that runs the button is faulty, but I'm definitely following the directions and pressing the correct location. There are instructions printed right next to the button telling you to 'gently' hold the button 3 seconds. It's one of those annoying / cheap galvanic skin sensor buttons that has zero 'give' to let you know if you're pressing the correct location on the device. I've tried holding the location for 10+ seconds, tried holding it for just a second or so, tried holding it for exactly 3 seconds, tried pressing it down hard, tried tapping it firmly, but it just seems to only respond maybe 1 / 10 attempts, then it just boots up and responds normally until I let it fall asleep again. I know the response is really light since all you have to do is very lightly tap it to get it to switch between voltage / battery percentage, so I'm not sure why it's so hard to get it to wake the screen. The jury is out on battery life / value since I was not able to find any battery tear-down videos on any model TPE battery. This is the only way to tell for certain if a lithium battery brand is giving you absolute garbage-quality components in your battery that will fail after a year or two (despite the cells still functioning for years, the battery has failed because every component must work). Unfortunately nobody has been kind enough to do this yet. I'll surely report back if this fails in less than the warranty period. ... show more

  • Super light for being a battery
Style: Group26 Buttons
Posts are backwards compared to normal battery. Battery is a tad bigger than normal battery with lip all the way around bottom of battery (for holding battery down), and alittle taller with center section of this battery sticking up. Works great.

  • Battery Was Empty!!! No Power at All!!!
Style: Group26 Buttons
I would've given this item a zero star, if I could! The battery that I received was, believe it or not, EMPTY!!! I mounted it unded the car hood, but no power at all!! Nothing!!! This is beyond defective, it's totally unacceptable to send an empty battery to a customer. Wow!!! I had to return it and was forced to immediately to AutoZone and get a led-acid battery which I was avoiding. ... show more
