FAQs
Is the Optima Red Top RTC 4.2 suitable for a daily driver?
Yes, it is suitable for daily drivers, especially those with higher performance needs or in colder climates where starting power is critical. However, its primary design is for starting applications.
Can I use this battery for deep cycle applications like RVs or boats?
No, the Red Top series is optimized for starting power (cranking amps). For deep cycle applications, Optima's YellowTop or BlueTop batteries are recommended.
How long does an Optima Red Top battery typically last?
Under normal conditions and with proper care, an Optima Red Top battery can last 3-5 years, often longer than conventional batteries due to its robust construction.
What type of charger should I use for this battery?
It's best to use a smart charger designed for AGM (Absorbent Glass Mat) batteries. Avoid standard chargers that may overcharge and damage the battery.
What does AGM technology mean for me?
AGM means the battery is sealed and spill-proof, offering better vibration resistance and the ability to be mounted in almost any position. It also generally leads to a longer lifespan and faster recharging.
Are there any special maintenance requirements?
The main maintenance involves keeping the terminals clean and ensuring the battery is properly charged. Due to its sealed design, there is no need to add water.
What is the Ampere-Hour (Ah) rating of this battery?
The Optima Red Top RTC 4.2 has an Ampere-Hour rating of 50Ah.
Troubleshooting
Battery does not crank the engine
Check battery terminals for corrosion and ensure they are tightly connected. Verify battery voltage; if significantly low, it may need charging or replacement. Ensure the battery is the correct type for the vehicle's starting requirements.
Reduced cranking power over time
Ensure the battery is being charged correctly. Clean terminals and check for any parasitic drains on the electrical system. If the battery is several years old, it may be nearing the end of its lifespan.
Battery case is swollen
This can indicate overcharging or internal damage. Discontinue use immediately and have the battery tested. Replace if damaged.
Acid smell from the battery
Although AGM batteries are sealed, a strong acid smell could indicate a leak or damage. Ensure terminals are clean and connections are secure. If a leak is present, replace the battery immediately.

Setup, Compatibility & Care
Setup:
- Verify Fitment: Ensure the battery dimensions (Length: 256 mm, Height: 200 mm, Width: 174 mm) and terminal type (Standard) are compatible with your vehicle's battery tray and cable connectors.
- Connect Terminals: Connect the positive (+) terminal first, followed by the negative (-) terminal. Ensure connections are clean and tight.
- Secure Battery: Fasten the battery securely in the vehicle's battery tray to prevent movement.
Compatibility:
- Vehicle Type: Ideal for starter applications in cars, trucks, and SUVs, particularly high-performance, tuned, or classic vehicles.
- Mopar Part Number: Also listed under Mopar 4868999AC.
- BCI Group: BCI 34.
Care:
- Charging: Use a charger specifically designed for AGM batteries. Avoid overcharging. A typical charger set to 12V with a maximum current of 50A is generally suitable.
- Cleaning: Keep the terminals clean using a wire brush and a terminal protector. The battery case can be wiped down with a damp cloth.
- Storage: If the vehicle is stored for extended periods, connect a trickle charger or periodic maintenance charger to maintain battery voltage.
