The GU1R model is designed specifically for the Import Tuner market (4 & 6 cylinder) for street/track vehicles and has enough cranking power for small block V8 race cars and hot rods with light electrical demands/accessories & standard compression. (Due to low capacity, this model is recommended as a TRACK ONLY model for high electrical demand vehicles like Audi, Porsche and others with lots of electronics & have a high parasitic draw where OEM battery is 60 Ah or higher). If this model is used in such a high demand vehicle, a lithium charger MUST be used if vehicle is not driven regularly and is going to sit for more than a week to ensure battery is not discharged. In most cases, an Intensity or Intensity Carbon model would be the recommended street/track car lithium upgrade.). This unit comes the popular U1R Group size (Mazda Miata and Spec Racer Ford), so it's small & light enough to mount in a variety of locations. This battery is the best "bang for the buck" in a lithium upgrade on the market for small & mid-size vehicles and incorporates the same technology as our race winning batteries used by nearly every OEM in their factory race cars and champions ranging from SCCA to Formula 1.

Braille Lithium delivers a higher, cleaner voltage which improves the performance of every electrical component and has shown to provide: quicker starting, improved management & data logging performance, less horsepower draw from the alternator due to efficient charging (5 times faster than lead), will last 3-5 times longer (especially under the harshest environments), much more reliable, all of this on top of the significant weight savings. They also don’t self-discharge, so if the battery is disconnected, they can sit for over a year and still have over 13 volts to start the vehicle. To get all these benefits in one simple step makes it a very cost effective upgrade!!

Due to low capacity of this lightweight battery, if the vehicle is not driven on a regular basis, a lithium charger must be used to keep the battery fully charged or a power disconnect switch used to keep the battery from being drawn down. Do not use a standard lead charger on a lithium battery.
