The OPTIMA Yellow Top battery is extremely safe and corrosion resistant, due to its completely sealed case. 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 is also ideal for seasonal use because of its very low self-discharge rate. That means you can store your seasonal vehicles all winter without regular charging and still spring out of the starting block when winter is over. .
Optima® YellowTop Battery
OPTIMA Yellow Top batteries, featuring SPIRALCELL TECHNOLOGY, are designed for all of your deep cycle needs. OPTIMA YellowTop is made to install and forget. No matter the conditions, be it dampness, heat, dirt or exposure to extremes in vibration or regular discharge, you can count on OPTIMA to deliver uninterrupted power. OPTIMA's ability to hold a higher voltage during the discharge cycle makes it possible to utilize more of the stored power in the OPTIMA compared to ordinary batteries. The YellowTop handles many discharges as well as re-charges without losing significant capacity.
Vehicles with computers, extra radios, electronic components, lights, winches, etc. will create excessive amperage drain that can damage a standard starting battery. The OPTIMA Yellow Top provides fast recharging and longer life due to its ability to cycle over 300 times.
Each OPTIMA Yellow Top Deep Cycle Battery is rated at 120 minutes of Reserve Capacity (running time before recharging) at a 25 Amp draw. .

Dual Purpose starting and deep cycling.
Lasts up to 2 times longer than other batteries.
Constant performance quality keeping your battery running at the same level even as it's being discharged.
More power in the inital 1, 3, 5, and 10 seconds of the starting process than comparably rated conventional lead acid batteries.
Ideal for seasonal use, fully charged, it can sit unused for up to 12 months at room temperature (or below) and still start a car.
15 times more resistant to vibration than other batteries.
Non-spillable and can mount in almost any position.
A little about Spiral Cell technology
Inside every Optima battery is a six-pack of SPIRALCELL TECHNOLOGY®. Traditional batteries have a stack of thick lead plates surrounded by acid. But OPTIMA® batteries feature two thin lead plates wound into a tight spiral cell, with an absorbent glass-mat in between to hold the electrolyte solution. This unique design allows for more power and increased energy, resulting in quick, reliable starts. OPTIMA batteries are the first and only batteries to feature SPIRALCELL TECHNOLOGY.
