BENEFITS OF THE YELLOWTOP®:
OPTIMA® YELLOWTOP® D34 Ultra high-performance SPIRALCELL TECHNOLOGY® AGM (absorbent glass mat) dual-purpose deep-cycle and starting battery. OPTIMA® YELLOWTOP® batteries have three times the cycling capability (rechargeability) with ultimate cranking power for your auto, car or truck to outperform traditional batteries. Perfect for powering heavy electrical loads, including winches, audio systems, inverters, and other demanding vehicle accessories and electronics. Lower internal resistance provides more efficient power output and faster recharges.
The OPTIMA® model number for this battery is D34. If you are replacing an OPTIMA® battery you already have, this model is the same as batteries marked 8012-021, 9012-021, 27992, SC34DA, N9934YEL or YEL34.
Includes applicable installation and/or height adapters for this battery

The following charging methods are recommended to ensure a long battery life: (Always use a voltage regulated charger with voltage limits set as described below.)
Recommended Charging Information
|Alternator:||13.65 to 15.0 volts|
|Battery Charger:||13.8 to 15.0 volts; 10 amps maximum; 6-12 hours approximate|
|Float Charge:||13.2 to 13.8 volts; 1 amp maximum (indefinite time at lower voltages)|
|Rapid Recharge (Constant voltage charger):||Maximum voltage 15.6 volts. No current limit as long as battery temperature remains below 125°F (51.7°C). Charge until current drops below 1 amp.|
|Cyclic or Series String Applications::||
14.7 volts. No current limit as long as battery temperature remains below 125°F (51.7°C). When current falls below 1 amp, finish with 2 amp constant current for 1 hour. All limits must be strictly adhered to.
