What Are the Key Specifications of the 46240-000RB Lithium Battery?

The 46240-000RB is a 12V lithium-ion battery with a capacity of 20–30Ah, depending on the vehicle model. It weighs approximately 8–10 lbs, significantly lighter than traditional lead-acid batteries. Its dimensions (10″ x 7″ x 6″) allow seamless integration into compact engine bays. The battery operates efficiently in temperatures ranging from -22°F to 140°F and features built-in overcharge/over-discharge protection.

Lithium-ion chemistry enables faster charge acceptance compared to lead-acid alternatives, with a 50% reduction in charging time during regenerative braking cycles. The battery’s energy density (150–200 Wh/kg) allows it to store more power in less space, making it ideal for hybrid vehicles with limited engine bay space. Its low self-discharge rate (1–2% per month) ensures reliability during extended storage periods.

How Does the 46240-000RB Enhance Vehicle Performance?

The 46240-000RB improves fuel efficiency by stabilizing voltage for start-stop systems, reducing engine wear. Its fast recharge rate supports frequent cycling, ideal for urban driving. Lithium-ion technology ensures a 5–8 year lifespan, outperforming lead-acid batteries by 2–3 years. It also reduces vehicle weight, enhancing acceleration and handling.

This battery’s adaptive power delivery system responds 30% faster to electrical demands during engine restarts, minimizing lag in stop-and-go traffic. By maintaining consistent voltage levels, it prevents flickering in LED headlights and ensures uninterrupted operation of advanced driver-assistance systems (ADAS). The reduced weight distribution improves cornering stability by lowering the vehicle’s center of gravity—a critical factor in hybrid models carrying additional powertrain components.

What Safety Features Are Integrated into the 46240-000RB?

The battery includes multi-layer protection against short circuits, overheating, and voltage spikes. A battery management system (BMS) monitors cell balance and temperature. Flame-retardant casing and shock-resistant design meet automotive safety standards (UN38.3, SAE J2464).

Eight redundant protection circuits prevent catastrophic failures, with emergency shutdown protocols activating within 0.8 seconds of detecting abnormalities. The aluminum alloy casing provides electromagnetic interference (EMI) shielding for sensitive electronics, while IP67-rated seals protect against dust and water ingress during off-road use.

“The 46240-000RB represents a leap in automotive energy storage. Its hybrid-focused design addresses voltage stability gaps in start-stop systems, reducing emissions by 4–6% in city driving. As lithium costs drop, expect wider adoption across EV segments.” — Redway Power Solutions Engineer

FAQs

How Long Does the 46240-000RB Battery Last?

5–8 years under normal conditions. Extreme heat/cold may reduce lifespan by 10–15%.

Is the 46240-000RB Covered by a Warranty?

Hyundai offers a 24-month/24,000-mile warranty. Third-party sellers may provide extended coverage.

Can I Install the Battery Myself?

Yes, but disconnect the negative terminal first and calibrate the BMS post-installation using an OBD-II scanner for optimal performance.
