Capacitors vs Batteries

Capacitors vs Batteries. So the big question here is which is better, a capacitor (or supercapacitor) or a standard lead-acid battery?

Capacitor vs. Battery: What''s the Difference?

We don''t use capacitors as batteries because they can''t store as much energy as batteries, and they also can only handle current in one direction. Additionally, capacitors are usually much smaller in size and weight than

batteries

According to this answer, you''d want to use capacitors rated for 400-450V, since per unit volume they give you most energy stored. You''ll want to charge them up to 95% of the rated operating voltage, and discharge them down to 50-100V. The lower discharge voltage depends on how good a switching converter you can put together to efficiently

Improve a car battery''s performance with capacitors

$begingroup$ 0.5*83*16.2² is the total energy stored - unfortunately this is erroneous as (a) the battery voltage (and hence the capacitor voltage) is more likely to be around 13V and (b) the capacitor voltage can only fall the same amount as the battery so the amount of energy available from the capacitors will only be a small fraction of the total. $endgroup$
