Specs

OPTIMA® YELLOWTOP® D31T 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 D31T. If you are replacing an OPTIMA® battery you already have, this model is the same as batteries marked 8050-160, 9050-160, 27993, D31T-1125, YEL31T, SC31DS, or N9931TYEL.

Recommended Charging

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.)

Model: D31T
These batteries are designed for starting and deep cycling applications and for use in vehicles with large accessory loads..


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.
