Secondly, I think 80% of the devices out there always take 2,4 6... batteries. It is rarely an odd number.
1) Not only have I taken "college physics," I've taught it. My research is in neurophysiology and electrophysiology, and guess what, the physics of electricity is a major component. At a Masters and PhD level. You might want to avoid making inflammatory assumptions, and focus on the topic. If you disagree with my information, post a correction -- WITH FACTS AND AN ARGUMENT. Your uninformative post was helpful to no one, and would have gotten an F in my class.
2) Try reading my post and thinking things through before posting. If two batteries have not been identically discharged, one would OBVIOUSLY charge to full capacity faster than the other (given the same mA charge rate). And this charger automatically goes to trickle charge once ONE of the battery is fully charged to prevent overcharging. It does NOT send one battery to trickle charge and continues to charge the other at full rate. So if a person was to take the batteries out once the Full light comes on, the weaker battery would be undercharged. Simple. So what is it you don't understand?
If you had read my post carefully, you would have seen that I wrote "That means the other battery MAY be undercharged. Better battery chargers will monitor and charge each battery individually." Note the word "MAY." That would indeed be the case if someone was to remove the batteries immediately after the charger indicates full since in reality, only the less-discharged battery is full. At a trickle rate, it may take several more hours for the weaker battery to reach full.
Frankly, I'm surprised you didn't already know this since it is a well-known criticism of these chargers that charge in pairs. Do your research and think before you post.
3) You wrote "Secondly, I think 80% of the devices out there always take 2,4 6... batteries. It is rarely an odd number." So what? When did i claim that most chargers were smart or charged in odd numbers? You're arguing a point no one ever made. What I said was that it's better to use a charger that can charge individually. And they're not rare. The highly rated LaCrosse charger, for example, charges and monitors each battery individually. So does the MaHa. And several others I own. Look them up on Amazon and see what people who really know about batteries say. In fact, you may even see my comments.
Seriously ... calm down and think things through before you post. And lay off the assumptions and insults.
