I think so too. I think the Maha Powerex charger is top of the line or close to it. But I got this thing about 3 years ago. Maybe the batteries nowadays have more capacity, so the curve is different and therefore it changes the charge termination behaviuor. The charger maybe would work fine for...
Guro...and your point is...?
Chipee...You see I think the maxim ic you mentioned is a chip right? That seems like it would be too much work and study for me.
When I googled it, I did come accross several message boards discussing early termination problems with smart chargers. The...
Yes thats correct. A timed charger will also fully charge a battery when a smart charger sometimes will not. Sometimes the smart charger terminates the charge too early as is the case with my Maha charger. The charge curves for different brands and capacities of nimh batteries may not all be...
I have a battery analyzer. Money is very much an issue. How often to you put electronic things down your pants? At least its low voltage DC so hopefully safe for you.
The current limiting resister is an interesting idea. I am not going to do it but that might work pretty well with a timer.
It was way to blunt sounding, sorry.
I have little knowledge of electronics other than a few semesters of required electrical engineering courses in college years ago. All I can remember from that basically is that v=volt, I=current and R=resistance.
I really dont want to make something or...
Ok.
It says right on the battery "Standard charge 270 ma for 16 hours" so I think its safe to say it would not be overcharged.
The Maha charger is terminating the charge process to early. The only way for me to defeat this is to use the break in feature setting the battery capacity to 2700...
1. These are Duracell batteries
2. The amount of energy put into the battery can exceed the amount stored by 150%, therefore the amount of energy you put into the battery does not mean that is what its capacity is. In other words, if you push 1500 mah of energy into a battery, it may only...
"Why do you think your Duracells are not being fully charged?
270mA for 16 hours will over-charge them and shorten their life."
Why do you think they would be overcharged?
"It is better to keep your mouth closed and let people think you are a fool than to open it and remove all doubt"...
Hello,
Does anyone know of a USB battery charger for nimh aa or aaa batteries that will allow you to manually control the current flow and time of charge on the computer screen? I wold like to charge my batteries specifically at 270 ma for 16 hours. I currently have a best of the best of the...
