[QUOTE="ftgu, post: 140714, member: 546136"] This came from [URL="http://www.optimabatteries.com/faq.asp#q9"]http://www.optimabatteries.com/faq.asp#q9[/URL] (i stand corrected about using a red top & a yellow top together) 9. Can I hook an OPTIMA up in parallel with my other battery? No, when hooking batteries together in parallel they should be of identical make, model, and of similar age. 10. Can I use an isolator with an OPTIMA? Yes, most any type of battery separator or solenoid can be used with an OPTIMA. The important thing to remember is that the charging voltage must be within the limits suggested by OPTIMA Batteries. If you are using an OPTIMA and a conventional battery, your system must charge each battery independently. Remember, some isolators cause a voltage drop, make sure your charging voltage AT THE BATTERY is sufficient. Continued undercharging of a battery will lead to premature failure and a drop in capacity. 11. Why does the OPTIMA last longer? The main reasons the OPTIMA battery has a longer life are: No shedding of active paste material. The SPIRALCELL design immobilizes the plates preventing the active past from working loose, which can cause plate to plate shorting. High purity lead-tin grid. Grid material in OPTIMA batteries is more resistant to grid degradation. A type of internal corrosion that affects the plates inside a battery as it ages. Sealed design prevents loss of water which can lead to plate dry out and failure. 12. What is the difference between your deep cycle and starter battery? The OPTIMA deep cycle battery utilizes a different chemistry for the active paste material on the plates, and a slightly stronger acid. This chemistry changes allows for a much longer life in cycling applications, with only a slight reduction in power. 13. What does deep cycle mean? Deep cycle means using the battery in an application that will typically discharge 60% to 70% or more of the batter y capacity. An automotive battery is an SLI (starting, lighting, ignition) battery. It's plates are designed to deliver maximum power for a short duration. Starting a car typically discharges an SLI battery only 1% to 3%. When an SLI battery is used in a deep cycle application, or in a vehicle with heavy accessory loads, the battery life will be shortened proportionally to how deeply it is cycled on a regular basis. 14. When should I consider a deep cycle? Any time you need the battery to supply all the operating power for a vehicle or other device. Additionally, deep cycle batteries should be used in vehicles that have heavy accessory loads where the alternator cannot maintain the battery in a fully charged condition. [/QUOTE]
