The following lithium vs. lead acid battery facts demonstrate the vast difference in usable battery capacity and charging efficiency between these two battery options: Lead Acid Batteries Lose Capacity At High Discharge Rates Peukert''s Law describes how lead
How much heat does a lead acid battery generate?
Heat is generated on recharge, float charge and discharge. The heat generated on charge is finite, i.e. once the battery is fully charged no more heat is generated but at this point the battery enters the float charge phase and as long as the battery is …
Five ways to extend the life of your lead acid battery. Part I
Most of us monitor the state-of-charge of a battery by the rough and ready method of ''observing battery voltage''. In the fast-charge installation imagined above, for example, voltages climb so quickly that it gives us the illusion that our battery is fully charged, and that we can therefore terminate the charge cycle believing that the job to be …
