個錶只可以顯示舊電當時嘅最大輸出. 即係一定要叉飽左, 個數值先至有意思.
如果舊電池個spec係350CCA, 叉飽左都只有300CCA, 需然著到車, 都係死左一半. 無可能返生.
如果舊池會唔會一個星期後已經散電散到著唔到車係無特別indicator可以指出.
只有由佢個max CCA 因年份而減弱時再推算佢已經開始老化的速度.

Step 6: Testing Battery
Now leave your battery for 1h and hook it up on car hadlight or any 12v bulb
Voltage of battery shoudnt drop lower than 12v


呢個方法好似 practical 啲
