الموضوع: بطاريه جافه ولاسايله للدايو ؟؟؟؟

من نفس اللينك السابق....فيه شرح للقدرة بتاعة البطارية وفوائد زيادتها:

7.2. Reserve capacity (rc)

the second most important consideration is the reserve capacity rating because of the effects of increased parasitic (key off) loads and of emergencies. rc is the number of minutes a fully charged battery at 80 o f (26.7 o c) can be discharged at 25 amps until the voltage falls below 10.5 volts. Deep cycle batteries are usually rated in ampere-hours. To convert reserve capacity to approximate ampere-hours, multiple rc by 0.4. for example, a battery with a 120-minute rc will have approximately 48-ampere-hours of capacity at the 25-amp discharge rate. more rc is better in every case! In a hot climate, for example, if your car has a 360 oem cranking amp requirement, then a 400 cca rated battery with 120 minutes' rc and more electrolyte for cooling would be more desirable than one with 1000 cca with 90 minutes of rc.
