標題: 鴨記電池
早幾日在鴨寮街買了散裝sanyo3600mA電池(有焊片的)自己焊，
之後用ICE差機用Cycle(循環放電及差電)的方式充電，
經過大概20個循環，
ICE差機的數據顯示：每次都係放約1200mA電就cut，及充約1800mA電就停。

部差機充放其他電是沒問題的。
想請教各師兄:
1. 我的sanyo3600mA電是否壞了?鴨記散裝電是否唔得?
2. 每次充入1800mA，放1200mA，餘下的三分一電(600mA)去了邊呢?
謝謝

鴨記好多電都係次品或假嘢, 要小心 D, good luck!

你試下每粒電單獨放電，然後一齊(整排)充電，咁樣會充得足好多。

街檔好多賣假電，買返有包裝穩陣D

KWS就百份百堅野???

散裝電 always have a risk ga la
especially ones in Ap Liu,
they are left overs from 1st match(factory, best match already sold to big brand for real racer) and 2nd match (big brand match to sell on street) and 3rd match (factory stick batteries) and 4rd match(RC shops matched for themselves) and 5th match (RC shops sell to users) and so on...
and actually
Ap Liu Street is not cheap anyway
just get batteries in RC shops la
if there is a problem you can go back and xxxx them ah ma

and I dunno about ICE charger
maybe your cycle function has setting on top mAh and min mAh (I think my Muchmore has this function)

maybe try to manually discharge, and charge with lower A(say 1A) and let it charge a whole day and see

and your question about the extra 600mAh, there is a chance that it wasnt even charged into the batteries and became heat

there is also a chance that these batteries are already half dead cos of improper storage...(humidity, low voltage, left too long and didnt get charged... too many reasons)

---> heat Loss

Agreed. I bought 2 packs of new original packed "death" NiMH from KWS too.

why dont you test the batteries?...
most shops will test for you ga wo...

Let me clarify. Very poor performance battery packs. (to me, = death) Wrose than my 1-year-old battery.

今晚再試用ICE 的4 step 充電程式去充那排我自己焊的鴨記Sanyo 3600，
即係Impulse, reflex.....之類 (總之係夾硬來) 的方法，
結果充到 2500mA，排電熱到65度攝氏，
停機再放電，可放1600mA。
真係激死，下一步我會如師兄所教，
找天放假，逐粒電充放，
看看是否有死cell

sounds a lot like those left over 5 or 6 times matching

dont buy in that store again

係啊，我醒起我買的時候，
間舖買剩六粒電在飾櫃，於是我話要晒，
個店員用電錶試俾我睇，
每粒電的電壓係0.8V至0.9V。
其實正常的NiMH電的出廠電壓應該係幾多?
好似唔會係0.8-0.9V o甘低，
師父們請指教下，等我下次買電醒少少。
