Braille Battery G20 Battery, 12 Volt

The Braille GreenLite G20 is purpose-built for the small displacement automotive (4 & 6 cylinder) and motorcycle market. Designed as a direct size replacement for the popular 20L or PC680 AGM battery, this 4.5-pound powerhouse delivers superior power and capacity at roughly one-third the weight. Small enough for flexible mounting in a variety of locations, it is the smallest, lightest, and most cost-effective lithium upgrade available for automotive and powersports applications.

This high-performance lithium battery uses the same proven technology found in Braille’s race-winning batteries trusted by nearly every major OEM in factory race programs, as well as champions across SCCA, Formula 1, and the Mazda Road to Indy series. Pro Mazda teams have run the same G20 for three full seasons after repeatedly burning through PC680 batteries.

• Quicker starting with a full volt higher voltage and minimal voltage drop during cranking
• More stable voltage improves engine management, data logging, and overall electrical performance
• Efficient charging reduces alternator horsepower draw (charges 5x faster than lead-acid)
• Lasts 3–5 times longer, even in harsh racing and powersports environments
• Extremely reliable with less than 1% failure rate and significant weight savings (up to 1/4 the weight of lead-acid)
• Zero self-discharge – can sit disconnected for over a year and still start the vehicle

Note: Due to its lightweight design and lower capacity, use a dedicated lithium charger or power disconnect switch if the vehicle sits for extended periods. Never use a standard lead-acid charger on lithium batteries.

Perfect for street cars, track vehicles, motorcycles, and lightweight performance builds seeking maximum weight savings without sacrificing reliability.
