Anyway funny thing is that over time my
Ni-Cad batteries seem to have lower and lower mA. My 1500mA stock batteries are now 1340 and 848ma respectively. I tried looking online and I was curious about the Cycling.
Anyway, today the oldest of my batteries discharged and charged at 700s. The Cycling options allows me to give a number of cycles. Since its already at half I though I might try cycling one more time after the recent charge. After 2 hours when I checked this time the battery is now at 800s.
Anyway this website says its bad. In fact according to this the proper way to charge a NiCd is a very slow charge 50mA or a “delta-v” which sounds like fast charge and stop when its hot. For my 1500mA batteries the slow trickle charge at 50ma is a 30 hour charge.
This is confusing me. 🙁
In summary. Charge your battery, but check every hour or as frequent as possible for any change of temperature. Any notable change in temperature marks its near full. It doesn’t have to be hot. Just make sure the batteries are “cool” (relative to room temperature). When it starts to feel hot, stop.
Final Solution. For those who don’t have smart chargers. My smart charger gives me the stats of my expenditure for the week. The best way to measure is by number of BBs fired, or in a larger and easier to handle grouping, magazines.
My SP130 G3 eats up 200mA per 500round mag. This is a very rough estimate. This value will not work the stock guns. This is very imperfect and intuitive idea of how much to charger per mag.
I recommend taking meticulous note on how many mags you used up in the day. Then time your charging. You can check on it every 15mins. Using the charger stats determine with the amount of time the passed how much mA the battery must have taken to charge.
Example. You have a fully charged bat. You followed the link above regarding the science of it. You know that while charging (you could be watching TV, or able to check on it every 5mins) there was a change of temprature marking its near completion.
With a Full batt, you expended 4 mags worth of BBs with you 300cap M4/M16 Mag into a specially made fully padded container (so that you can recycle the BBs, or using Bad BBs).
You have a charger that charges 300mA (per hour). It would take 5 hours for you 1500mA battery. When the battery is cool, you start charging and begin a timer. You check on it every 5-10mins, while watching something or doing chores. You come back at around 1 hour and when there is a very noticeable temperature change you stop the timer.
You learn those 4 mags equal 1 hour of charging. So 15mins per magazine. You right it down on the batt, with a silver pen on the black electric tape. If your meticulous you would probably note your magazine consumption.
