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 …
