The likelyhood that the single lead acid could crank the diesel when the Maxwell wouldn''t is not likely. You might be able to if the Maxwell failed internally and you switched over the cabling, to start and get to a place the Maxwell could be replaced. To be honest, i''ve found it far more reliable that lead acid batteries.
Batteries can store a significant amount of energy, but supercapacitors have a relatively lower energy density. This limits their use in applications that require long durations of energy supply. Another challenge is the limited voltage range of supercapacitors. Batteries can operate at higher voltages, allowing for more efficient use.
Most sealed lead-acid batteries can only handle 200-300 charge-discharge cycles before performance starts to degrade. This makes them less suitable for applications requiring frequent charging, such as solar energy storage. Lead-acid batteries are also sensitive to deep discharges, which can damage the cells and shorten their lifespan.
The potential for supercapacitors to replace batteries lies in their ability to meet specific energy demands while offering a longer lifespan and lower environmental impact. As
For example up to three lead-acid batteries in a truck are replaced by identical-looking supercapacitors to give superb cold starting instead of the all-too-familiar no starting at all on a cold day. They make the bus doors work when the power goes down: they make the regenerative brakes work when a hybrid car loses its electrics.
Supercapacitors are better than batteries as a source of power, but they are worse than batteries at storing energy the cars, supercapacitors are sometimes found in KERS (Kinetic Energy Recovery System), where they absorb a large amount of power as the car slows down, only to throw this power back into the motors seconds later.

We can use Li-ion battery banks (these are costly but better than lead-acid batteries) which will help to run the vehicle smoothly when the speed is constant, but when the peak load is applied then these batteries will go under pressure. So, this pressure can be handled by supercapacitors. • Phone Batteries
Q1: Can supercapacitors replace batteries entirely? A: While supercapacitors excel in rapid charge/discharge cycles, they currently can''t match batteries in terms of energy density for long-term storage.
The major problem of lead acid battery banks is the phenomenal hike in the cost of lead and the use of corrosive acid. Warm climates accelerate the chemical degradation leading to a shorter battery life. A better solution, as often advocated, is to use a century-old technology in which nickel-iron (NiFe) batteries were used.

A better energy storage option is clearly needed, and supercapacitors seem to be the only technology that is close to replace the battery. Batteries store energy in electrochemical form, reactions inside the cell release electrical carriers that form a usable electric current.
Recharging your mobile phone or your electric vehicle in a few minutes sure sounds appealing. Supercapacitor technology has the potential to deliver that kind of performance that batteries currently can't, and while batteries are constantly improving, the pace of development is not very fast.
Batteries have the disadvantage in this characteristic due to the chemical reactions that take place to store and release energy. Supercapacitors have faster charge and discharge rates than batteries because the chemical reactions that take place within batteries take longer to release electrons than the electrical discharge in supercapacitors.
In some applications though, a hybrid configuration prove to be the most useful. The supercapacitors provide the quick burst of energy for an application, while the batteries handle the long-term energy needs. In some applications, a hybrid configuration may prove to be the most useful.
