Another quality criterion for batteries is the self discharge. This determines how long a battery can be stored and how much power is necessary to hold the charge.

| False investment hydrogen research for fuel cell cars
|
| |
If all the billions for the hydrogen research would have been invested for better a lithium battery technology, we would already have hybrid cars to go 80% by electric power.
