I keep seeing posts about them removing the batteries as soon as they buy their toys because it will cause moisture or something.

But that made me think about it and I noticed most of my toys, I never removed their batteries... so I was wondering if its safe to keep them? I started collecting around the end of Energon line.

You're best served taking them out. Those little watch cell batteries are fairly durable, but AA and AAAs, especially the cheapo-noname brand ones in TFs aren't quite as sturdy. In a dry climate they'll probably be safe for a few years, but moisture can damage things in a hurry. It's better to take'em out and not need to than find your fig wrecked a year later.

I didn't notice but I had two graphing calculators with Duracell batteries and they all leaked inside and now the calculators don't work

I had just changed them a few months ago

It depends. If you play with the electronics fairly often, then they should be fine until they no longer work. If you don't use the electronics at all, then take the batteries out. The button cell batteries are extremely hardy little things. My Armada Unicron still has the factory installed batteries inside it!

Cell Batteries? Those small circles batteries?

That's a relief but I don't really know which one use AA or AAA batteries. I know I removed Dark Scorponok's batteries because his sound annoyed me.

I never use the sound or at least very rarely. The only one I use is Animated Megatron's.


Those are the only one I have in my head that make sounds are:

===================
I am not sure if RID Leader Optimus Prime and Ultra Magnus has electronic sounds on them.

Armada Supreme Unicron.

Energon Ultra Landmine.
Energon Supreme Unicron.
Energon Supreme Takara Omega Supreme.

Cybertron Voyager Vector Prime, Galaxy Force Vector Prime.
Cybertron Ultra Cryo Scourge, Cybertron Defense Red Alert, Sky Shadow, Menasor, Wing Saber.
Cybertron Leader Optimus Prime, Galaxy Force Optimus Prime, Metroplex, Galvatron (not sure if he has sound but I plan on getting rid of him anyway).
Cybertron Supreme Starscream.

Movie Leader Brawl, Nightwatch OP, Premium OP.

Animated Leader Megatron.
===================

double a batteries don't leak on my figures me and my friend were playing with a batterie it did'nt leak until we crushed the bottom check out his profile on youtube his profile is MOFHACE and is full of awesome deathmetal bands from the 80s 90s ETC.

Most figures from RiD to Cybertron either don't come with the batteries, or use the button cell batteries. All of the movie Leader class figures have batteries installed for their "Try Me!" function, and so does Animated Megatron. All of them use AA batteries.
