Whether you spend your time on the water fishing, off shore, recreationally, or sailing, OPTIMA has the right battery for you.
Fishing: Stay out on the lake longer. Your wife will love that.
You procrastinating types will love how Optima Batteries hold a charge. You know the drill. Fishing season rolls around and you’re stuck digging out your old charger or worse, you’re stranded on the water.
Most batteries lose their charge after a few months. Not the BlueTop. Because of its low rate of discharge, when stored with a full charge,
it can go unused for up to one year and still power up your live well, GPS and graph. A low internal resistance gives you a more immediate
power punch and a cleaner, more consistent surge. It also recharges faster, getting you back on the water quicker so you can recharge.
Off Shore: Never end up on a Deserted Island.
Saltwater can cause more corrosion than freshwater. Fortunately, the BlueTop has a maintenance-free, completely sealed case that eliminates
corrosive damage that negatively impacts the battery’s performance. Also, you can mount it anywhere in your boat because it’s leak proof and
with 16X the vibration resistance of traditional batteries it can handle the beating of pounding waves. They also have more power so you can
run all your electronic gear and never have to worry about drifting out to sea because of a dead battery.
Recreational: A Day of Boating will Never be a Day of Trying to Start the Boat.
Nothing wrecks a day out on the water like a dead battery. It’s the life-blood of a boat. That’s why it’s important to get one you can
depend on like the BlueTop. It has a faster recharge, up to 2X the life of ordinary batteries, doesn’t leak, and has enough power to run
your GPS, running lights and stereo without leaving you dead in the water. And there’s a model to fit every type of boat.
Sailing: A Dead Battery isn't exactly Smooth Sailing.
Clear weather. Beautiful skies. The ocean stretching as far as you can see. Almost ideal conditions for sailing if it wasn’t for your dead
battery. It’s time to upgrade to a BlueTop. You’ll love the no maintenance, leak proof design because you can mount it anywhere. And because
of a faster recharge, you can enjoy the peaceful sound of waves splashing your bow rather than a noisy generator.
What is the Difference?
Durable The OPTIMA® BlueTop battery will keep you on the water longer. Its patented SPIRALCELL® Technology means more running time, faster recharge, and up to twice the life of traditional marine and RV batteries.
Vibration Resistant The OPTIMA® is over 15 times more resistant to vibration than other batteries. The constant vibration and jarring from waves can be deadly for traditional marine batteries. The tightly wound construction in OPTIMA® batteries minimizes plate movement and subsequent damage caused by harsh conditions - extending battery life.
Non-spillable/Maintenance Free The OPTIMA® is spill-proof and maintenance free. Because of its completely sealed case, OPTIMA® batteries are extremely safe. Acid can't leak or spill, making them clean, user-friendly and environmentally sound. In addition, the maintenance free sealed case design eliminates the need to add water or clean terminals. OPTIMA® Blue Top batteries are spill proof, so they can be mounted anyplace inside a boat, in almost any position.
Retains Charge Longer In the off-season, sometimes marine batteries sit for months at a time and lose their charge. But the OPTIMA BlueTop battery has such a low rate of self-discharge, that it can go unused for up to one year without recharging, if kept at or below room temperature. And because of its low internal resistance, it recharges faster, getting you back on the water quickly.
OPTIMA® offers three battery models for your marine and R/V needs: the 34M, D34M, and D31M.
OPTIMA's
D34M and D31M BlueTop batteries are dual-purpose batteries. They can be
used in any deep cycle (marine accessory, R/V, trolling motor) or
starting applications.
OPTIMA's 34M BlueTop battery is a
starting battery. Although you can use a deep cycle battery in any
application, starting batteries can only be used for starting
applications.
