Battery entrepreneurs and users often ask,"Can batteries be revived?" A battery failure doesn't always imply end of battery life. Rather than shedding a pack, innovative entrepreneurs are finding business models to give retired batteries a second lifetime. Considering the growing amount of batteries which are being discarded, such business opportunities can only increase.
The three main battery defects are low ability, high internal resistance and elevated self-discharge. Capacity fade occurs naturally with use and time; resistance growth is common using nickel-based batteries; and elevated self-discharge reflects possible pressures endured within the field. Capacity loss may frequently be reversed with NiCd and NiMH; lead acid with sulfation can sometimes also be made better. (See BU-901: Basics in Battery Testing.) Capacity fade happens naturally with time and use; resistance growth is common using nickel-based batteries; and elevated self-discharge reflects stress. Capacity loss can be reversed on nickel-based batteries influenced by memory; a few lead acid with sulfation may also be improved.
Batteries can be classified into portable, wheeled mobility, starter and stationary systems. Not all batteries are well worth servicing but you will find jewels among the rubbish. To make a profit, a few simple battery knowledge is going to be necessary, such as familiarity with chemistries and understanding voltage, Ah, charge procedures and C-rate. Above all, you need a knack to see everything to touch and what to do. Knowing the prior life and the way the end of battery life depends will play a large part in how well these lost batteries can be redeployed.
