標題: 點測試出排 ni-mh 電有冇死電?
我試過用隻他錶, 度 volt, 粒粒都有 1.2 -1.3v
咁係唔係就代表冇死呢? 應該唔會咁 simple 的...

咁仲應該 test d 乜呢?
thx

You should add a relatively high current load (e.g. discharging the battery by a battery charger such as Much More Cell Master) to the battery and then check the voltage of individual cell.

If you don't have a high current load, the simplest way (but not so accurate) is to use a 540 motor connect to each cell one by one and check the cell votlage (e.g. if it drops to below 0.8 even after charging, the cell is probably death). This method could help to identify the very poor condition cell.

thx first
咁即係如果半死的就 check 不到出來?

Under the same loading, the more the voltage drop, the worse of the cell condition is.
