(5 1/2 hours?)

(depends on how hard your computer is working)

*fast charge* vs *trickle charge*

(‘fast charge’ has higher ‘charge voltage’ + ‘amperage’)

‘fast charge’ is used when battery is at less than 80%

(then the weaker/longer ‘trickle charge’ is used)

.

(how long does it take to fully charge a ‘dead macbook battery’?)

(apple claims it takes 2 hours to charge battery from 0% to 80%)

(apple claims it takes 1 hour to charge battery from 50% to 80%)

(then 2 hours to charge from 80% to 100%)

(3 hours to go from 50% to 100%)

(~4 HOURS TO GO FROM 0% TO 100%)

.

Trickle charging means charging a fully charged battery at a rate equal to its self-discharge rate, thus enabling the battery to remain at its fully charged level;

this state occurs almost exclusively when the battery is not loaded, as trickle charging will not keep a battery charged if current is being drawn by a load

A battery under continuous float voltage charging is said to be float-charging

For lead-acid batteries under no load float charging (such as in SLI batteries), trickle charging happens naturally at the end-of-charge, when the lead-acid battery internal resistance to the charging current increases enough to reduce additional charging current to a trickle, hence the name.

In such cases, the trickle charging equals the energy expended by the lead-acid battery splitting the water in the electrolyte into hydrogen and oxygen gases

Other battery chemistries, such as lithium-ion battery technology, cannot be safely trickle charged.

In that case, supervisory circuits (sometimes called battery management system) adjust electrical conditions during charging to match the requirements of the battery chemistry

.

*for ‘Li-ion batteries’ generally, (and for some variants especially), failure to accommodate the limitations of the (electro-)chemistry of a ‘cell’, with regard to ‘trickle charging’ after reaching a ‘fully charged state’, can lead to ‘over-heating’ +, possibly to ‘fire’ or ‘explosion’*
