Hi Piggy, everyone has different ways to do things and since you asked what I do, I will give you my two cents..LOL

Well, you did not say if you were talking about Ugobe batteries or RB batteries, but I treat both the same when it comes to batteries.
I do not leave the batteries in, but I do not recharge them either, If it is going to be a short rest, like the phone rings or I have to do something and I KNOW I want to continue playing with the pleo, Pleos... then I just turn them off and leave the battery. Then you just have to turn Pleo back on.. IN the case of Pleo RB it is a little different in that if I left the battery in, he or she could turn them selves back on with the wake up clock battery function. not a good idea if you are a pleo on a high shelf or dangerous place where you could fall.

I don't need or want anymore pleos with broken necks and a RB that is injured is not fun either. sure you can nurse them back to health, and it may be "cute" to watch them cry or whimper for a few seconds, but if you have ever heard the scream of an injured pleo, the leg for example, you will think it is very realistic and I find it hard to deal with.. you know it is a "robot" not real< but the sounds are heart wrenching to me.. Also, who knows if the accidental fall will result in a "limp" for a few days, or a broken neck cable. which is a lot tougher to deal with....

I also have 28 Pleos, mostly ugobes, but five are Pleo RB, and I can't afford 23 Egg batteries for all those Ugobes right now, and they seem to have "VANISHED" and those egg batteries are pretty important right now.. I do not want to leave them in the pleo for an indefinite time where they can be slowly draining the life out, and it is just as easy to keep them nice and clean in the box they came in and have them ready to put in anytime, where they are clean, safe and not be damaged or short lived in any circumstance.
