GU1R Combo Features

The GU1R model is designed specifically for the Import Tuner market (4 & 6 cylinder) for street/track vehicles and has enough cranking power for V8 race cars and hot rods with light electrical demands/accessories. (Due to low capacity, this model is NOT recommended for high electrical demand vehicles like Audi, Porsche, Mercedes and other sedans with lots of electronics & have a high parasitic draw. Call for to see if this battery is suitable for your application). This unit comes the popular U1R Group size (Mazda Miata), 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.

Race Winning Lithium Technology Designed for the Enthusiast and the Professional. Tremendous Weight Savings, Original Equipment Direct Replacement Sizing and Superior Starting. Excellent Off-Season Storage Performance. Brass Terminals, and High Amp Design. RoHS, Environmentally Friendly and DOT Approved. 

*Marine Sealing is available and required for batteries used in marine or other applications where unit may be exposed to water directly (light mist or spray), as lithium batteries are not intended to be exposed to any water unless marine sealed, which makes the more water resistance, but not “waterproof”.  (additional cost, varies by lithium model)

** PbEq equals Lead-Acid Equivalent also known as LAH Lithium-Amp-Hours. This means that an 18 LAH PbEq (6AH) Lithium Iron Phosphate battery could perform the same near as an 18 AH Lead-acid battery under a high rate discharge in comparison.
