Optima batteries offer 15 times the vibration and pounding resistance of standard vehicle batteries.
Optima Batteries are very tough.
The Optima's patented SPIRALCELL Technology is the key to the Optima's performance.
Inside these unusual batteries is a six-pack of Spiralcell Technology. Traditional batteries have a stack of thick lead plates surrounded by acid. But Optima batteries incorporate two thin lead plates wound into a tight spiral cell, with an absorbent glass-mat in between the layers to hold the electrolyte solution. This unique design allows for more power and increased energy, resulting in quick and reliable starts. Optima batteries are the first and only batteries to feature Spiralcell Technology.
All Optimas are also spill-proof, highly resistant to heat and cold, can be mounted in nearly any location within your vehicle and at any angle, and can be stored for long periods without maintenance.
Optimas are sealed and do not leak. They can be mounted in vehicle sideways or even upside down and they will not leak acid like standard batteries. With an Optima, you will not see your terminals or battery tray corrode as you would with standard batteries. If you want high battery performance for your vehicle, an Optima is the battery for you.
Optima manufactures various models of its batteries. Some feature side terminals and some lack them. Some have additional top terminals and some lack them.
The 800U Red Top and 750U Yellow Top models we carry have the side terminals fitted for added flexibility in wiring and mounting options. Offroad vehicles are usually equipped with items such as winches and auxiliary lights, and the extra terminals provide extra wiring options and configuration possibilities.
One option for the side side terminals is to fit the JL Audio Battery Terminal Adapter Set. The JL Audio Battery Terminal Adapter Set threads into the side terminals on batteries like the Optima 800U Red Top and 750U Yellow Top Batteries and converts the side terminals into standard tapered posts to allow fitment of standard battery terminal connectors.
The tapered posts in this Adapter Set are constructed from nickel-plated brass that is machined to precise tolerances for a perfect fit with all JL Audio Battery Terminal Connectors. All hardware is stainless steel for corrosion resistance.
The D31M Blue Top model we carry has additional top terminals.
Our Red and Yellow Optima batteries come equipped with a quickly detachable carry strap.
On the Defender, two batteries fit nicely into the space previously occupied by the large factory battery. John's Defender is fitted with dual Yellow Top Optimas wired in parallel.
Adding dual Optimas in the Disco2 is more difficult, as the vehicle's battery receptacle accommodates only a single Optima. For these vehicles, a fine choice is the D31M Blue Top, which has approximately 1.5x the power of the standard Red and Yellow Optimas. Installing the D31M Blue Top into a Disco2 is very simple and a drop-in installation.
The D31M's supplemental post terminals make hooking up winch and auxiliary light connections very simple.
To install such connections, it is a very simple matter to unthread the wing nuts on the supplemental post terminals and attach the power cables.
There are many reasons to run upgraded and/or multiple batteries. If you have fitted powerful auxiliary lights to your vehicle like these Hella Rallye 4000 Lamps, you might consider replacing your factory battery with an Optima Battery or Batteries.
If you like to run your auxiliary lights on the trail at night, you are a good candidate for upgrading your battery or batteries. Running lights like this on the trail will put more strain on your battery or batteries.
If you combine with your auxiliary lights with a winch like this Superwinch X9, then you need upgraded batteries even more. If you venture offroad at all, even on easy trails only, you should have a winch mounted to your vehicle.
If you equip your vehicle with an Engel Freezer Fridge, you might want to upgrade your battery. The Engel Freezer Fridges are extremely efficient and draw very little power, but if you equip your vehicle with lights and air compressors and a fridge, even the smallest power draws begin to add up and will eventually put a strain on your current battery or batteries.
On longer trips like our Rubicon and Dusy Ershim trips, we like to take along laptop computers to download the photos from our digital cameras. We hook up the laptops to power inverters and run the laptops off the vehicles' battery power. This is yet another power drain on our vehicles' electrical systems.
While we use our laptops only to download photos, many others use their laptops to run sophisticated GPS and mapping software inside their vehicles. Unlike our laptops, these mapping laptops are usually on all day.
If you fourwheel, you should deflate your tires before hitting the trail. Deflated tires will give you added traction on the trail and a more compliant ride. If you use a small air compressor like the ARB Air Compressor, it will take you a while to air up your tires. The ARB Air Compressor was designed to operate the ARB Air Locker and is not really recommended for the constant-duty use required to inflate four large offroad tires.
There are very powerful electric air compressors on the market, such as this Trail Air Compressor from Oasis Offroad Manufacturing displayed at the 2002 SEMA Show. This unit is powerful enough to operate a 1/2" impact wrench without a separate air tank. However, this unit draws a tremendous amount of power and will quickly drain your batteries.
Underhood welders like the Premier Power Welder are very useful items to have on the trail. These units, however, draw very large amounts of power. If you fit one of these units, we recommend that you not only upgrade your battery to an Optima but also fit a second Optima Battery.
For wiring two batteries in parallel or for wiring multiple accessories, we recommend the JL Audio Battery Terminal Connectors. These connectors feature a modular design with one captured-wire connection and two Power Ring receivers. The central captured-wire connection accepts 1/0 AWG wire directly or 2 AWG or 4 AWG wire with the supplied machined adapter sleeves. The two outer connections accept JL Audio Power Rings with captured-wire connectors for 1/0 AWG, 2 AWG or 4 AWG wire (the 2 AWG and 4 AWG Power Rings are included), or rubber blanks if less than three power wires are required. These large power capacities are perfect for wiring high-amperage equipment like winches, heavy-duty air compressors, portable welders, and so on.
For powering your high-amperage applications, we recommend the JL Audio 1/0 AWG Power Wire. The JL Audio Power Wire is constructed of highly flexible, 99.999% pure oxygen-free, fine-strand copper to true AWG specifications. Don't confuse the JL Audio Power Wire with inferior wire that claims to be 1/0 AWG, but is really something else. The compacted strand orientation and the very high strand count provide excellent conductivity while maintaining outstanding flexibility to facilitate routing.
Compare these two power cables. The cable on the left is standard 2 AWG power cable. The cable on the right is the JL Audio 1/0 AWG Power Wire. The difference is dramatic. Only top-quality power cable like the JL Audio Power Wire features such high-quality copper wires. The thicker wires on the 2 AWG power cable enable air to get into the cable, causing oxidation of the copper and reducing conductivity. The thicker wires also make this 2 AWG cable very inflexible and difficult to route in confined spaces.
Note how much more flexible the JL Audio Power Wire is, even though it is 1/0 AWG and the other cable is 2 AWG. When routing your thick power cables, the flexibility of the JL Audio Power Wire really comes into play. You can route this thick Power Wire around and through places where inferior wire will not work. All JL Audio Power Wire is covered with a flexible PVC jacket that is resistant to oil and gasoline and has a super smooth finish for ease in running the wire through confined spaces.
The red color designates positive applications and the black color designates ground applications. For applications like terminating power and ground connections to factory battery connectors and winch solenoids, as well as for supplemental grounds, we recommend the JL Audio 1/0 AWG Ring Terminals.
Most don't realize that the ground connection is every bit as critical as the positive connection. A poor ground degrades system performance and will cause a multitude of other problems. The JL Audio Bolt-On Master Ground Lug for 8, 4, 2, and 1/0 AWG Power Wire Ring Terminals will ensure proper grounding that lasts under the most demanding conditions.
For wiring smaller accessories like auxiliary lighting, we recommend the JL Audio Power Distribution Block, which features a captured-wire connection input that accepts 1/0 AWG wire directly, or a 2 AWG wire with the supplied machined adapter sleeve. The four outputs flower outward to allow for a multitude of wire routing options. The outputs are the captured-wire type and accept 4 AWG wire directly, or 8 AWG wire with the supplied machined adapter sleeves.
