I would go with an Optima or an Odyssey. You will get better results and a longer battery lifespan, especially if you use the truck with accessories, i.e a portable refrigerator, electronics, lights or etc.
thanks for your advise. actually, I email Optima to ask whhich model could fit my RR, below is what I got. I guess that's the reason I start this topic, I wish maybe some one can suggest me the detail models instead just the brand name.
anyway, I think they explain it very clearly
Unfortunately, Optima does not offer an exact-fit replacement battery for your Range Rover. You can measure the dimensions of your existing stock battery to see if there’s an Optima that will work for your vehicle. Below is a link to the product specification page where you can find exact dimensions for all Optima batteries:

Alternately, you can check the internet enthusiast forums for your vehicle to see how others have done custom applications with Optima batteries.
RedTop: Use this for normal engine starting where an alternator immediately monitors the state of charge and provides energy to the battery whenever it is needed. This would describe most stock vehicles.
• Automotive & RV under-hood starting
• Heavy equipment where starting is primary function
• Diesel powered vehicles with no aftermarket electronics
YellowTop: Use this when electrical loads are higher than average, or when the discharge cycle is more than typical engine starting, such as vehicles without alternators. This also includes vehicles with significant electrical loads that may exceed the average alternator output (for example aftermarket audio system, GPS, chargers, winch, snowplow, inverters, drag cars). This can also include vehicles that have a lot of electronics from the factory, such as a minivan with power sliding doors and a DVD player, especially if the DVD player is used when the engine isn’t running.
• Racing vehicles without a charging system (alternator or generator)
• Dedicated drag racing vehicles
• Diesel powered vehicles with aftermarket electronics
• Car audio/video applications exceeding 250 watts over the OE system
• Vehicles or heavy equipment with inverters, hydraulics, winches or other accessories
• Electric vehicles
If you are using an Optima battery in a custom application, it is important to consider the following:
· Hood Clearance – There should be at least ¾” clearance between the top of the battery terminals and the underside of the hood.
· Trunk/Interior Mounting – If your battery is mounted inside the passenger compartment or trunk (common in many European makes) the battery must be vented to the outside of the vehicle. Optima group 27, 51, 78, 34C, and 31 batteries all have ports for connecting a vent hose.
· Side Terminals – Optima 34/78, D34/78, 75/25 and D75/25 batteries have both top and side terminals. If you are using one of these batteries in a vehicle that uses the top terminals, it is important to ensure that the side terminals cannot come into contact with anything metallic (for example, the firewall or fender well), thereby causing a short. We suggest keeping the post protectors on the terminals you are not using. Do not connect a winch to the side terminals.
· Battery Modifications – Cutting, drilling, trimming or otherwise modifying your Optima battery may present a safety hazard and will void the warranty.
· Mounting – Your Optima battery must be securely mounted. The terminals are not intended to be used to secure the battery. Using the terminals in this way will damage the battery and void your warranty.
· Heat – Protect your battery from high heat, such as turbochargers or exhaust manifolds
