OPTIMA 75/25 RedTop Battery Manufacturer Optima Batteries Model OPTIMA 75/25 RedTop Battery Weight 33 Volts 12 Amp-Hour 44 CCA 720 Length 9.4 Width 6.8 Height 7.6 Terminals Dual - Top & Side Warranty 18 Months Free Replacement and 18 Months Pro-Rated. 36 Months Total Chemistry AGM SLA, SPIRALCELL Color Red Top In any vehicle or equipment that will use the battery only for Starting, Lighting, & Ignition requirements and has a properly working alternator, the OPTIMA Red Top™ Starting Battery will perform extremely well, often providing up to two times longer life than conventional batteries. If the vehicle has few or no after-market accessories and uses a stock or upgraded alternator, the OPTIMA Red Top Starting Battery is the appropriate choice. Remember, it is possible for the customer to have a completely discharged Red Top OPTIMA that will not start their engine; the advantages of the Red Top are that it can accept a rapid recharge and it will recover from discharge many more times. To provide the customer the best OPTIMA solution, it is, necessary to consider both the application and the charging system before recommending the correct OPTIMA. For example, if your customer has a Ford Expedition with an after-market alarm system, which OPTIMA would you recommend? If the customer drives the car every day, the Red Top would be the correct choice, since the amperage drain will be nominal and the battery would be recharged on a daily basis. However, if the customer stores the vehicle for a long period of time with the alarm system engaged, you should recommend the OPTIMA Yellow Top, since the amperage drain over several weeks would damage a Red Top and reduce its life.

You must double check these specifications before purchasing and installing. Suitable replacement batteries often vary in size, so be sure the dimensions and terminals work with your vehicle. Additional adapters are sometimes necessary. OE CCA: 525.
