D oes it mean that I 0.25 (current of 1/4 hour discharge) equils C 20 x 4 ? No, it is not correct. Lead-acid battery capacity for 15-minute (1/4 hour) discharge usually is slightly less then half of C 20.That is why I 0.25 is not more then C 20 x2. As we see discharge current and discharge time ore not directly proportional.

The effective internal series resistance of a normal capacitor is much greater than the effective internal resistance of an automotive battery in good condition. That means that the capacitor will not help stabilize the voltage. But if the battery is an older second battery powering a high powered sound system then there may be a benefit.
The global market of lead acid is still growing but other systems are making inroads. Lead acid works best for standby applications that require few deep-discharge cycles and the starter battery fits this duty well. Table 1
The LTC3305 lead acid battery balancer is currently the only active lead-acid balancer that enables individual batteries in a series-connected stack to be balanced to each other. Figure 2a shows an application in which a single LTC3305 is used to balance four series-connected lead-acid batteries.
Super-capacitor is a new type of energy storage element that appeared in the 1970s.

The model is based on a 12 V 200Ah lead-acid battery. The main element of this battery is a voltage source, Em, which represents the open circuit voltage of the state of charge for the battery. However, due to a chemical reaction inside the lead-acid battery, this open circuit voltage is overlaid by the overvoltage.

The only sensible use of a capacitor for starting that I''ve seen is a hybrid lead-acid with a capacitor. The battery charges the capacitor, which provides a large but brief surge current to start the engine. This surge capacity allows using a bit smaller lead-acid portion since the peak current is no longer the limiting factor.
