短路存放不是特殊偏方喔! 很多玩車好手都這樣做!
我有一顆TAMIYA1400mah NICD電池，2006至今仍可放電超過1000mah...
以下為NASA針對NICD使用、儲存以及活化的文章:
http://www.nasa.gov/offices/oce/llis/0644.html
建議先讀GUIDELINE NO. 1以及NO. 6;
小弟摘錄重點
GUIDELINE NO. 1 - 非使用時，電池應於放電後短路，以低溫儲放。Flight batteries should be maintained in a discharged and shorted condition and stored at cold temperatures when not required for "critical" spacecraft testing.
GUIDELINE NO. 6 - 電池短路儲放超過14天後，應活化後再予以使用。活化時環境溫度約攝氏20度。A battery stored discharged and shorted for a period greater than 14 days should be activated with a "reconditioning cycle" prior to placing it in use. The reconditioning cycle is performed at 20 degrees C and is defined as follows:
步驟1. 以C/20充電40小時。1.Recharge at C/20 (C/*** indicates recharge or discharge rates in terms of "name plate" battery capacity, e.g., C/20 = 1/20 of the capacity listed on the battery nameplate) for 40 hours (+/- 4 hours)
步驟2. 以C/2 放電至任一電芯電壓降至1.0V。2.Discharge at C/2 constant current rate until the first cell reaches 1.0 volts.
步驟3.以1歐姆的電阻，將所有電芯放電至電壓低於0.03V為止。3.Drain each cell with a 1 ohm resister to less than 0.03 volts.
步驟4.將各個電芯個別短路四小時。4.Short each cell for a minimums of 4 hours
步驟5.以C/20充電40小時。5.Recharge battery at C/20 constant current rate for 40 hours (+/- 4 hours)
