No offense to Nebulas, but please don't fearmonger what you don't understand. Batteries don't explode very often at all. Runaway thermal reactions are exceedingly rare and, in fact, when they do happen ECF moderators will immediately ask you to fill out a form explaining the circumstances, brand, and also supply pictures of the battery (pics or it didn't happen!). I think I've read about 3 or 4 since I joined the ECF and 2 of them were passthroughs that were left plugged in unattended (which is why I don't recommend passthroughs). Had you actually read just the first page of the thread you posted you would have known that the guy used the wrong charger. He was using a 5v charger on a 4.2 volt maximum device. The OP even said "Ok, so based on the replies I would guess that the problem was that I used an incompatable charger. Nobody got hurt and no property was damaged so we can call it a hard lesson learned."
To answer the OP's question:
It shouldn't matter, but you'll need to look at the charger to get the output information. If the output of the charger is 4.2v and 420ma (milliamps, not mah (hours)), then you should be good to go. If you have a regular old, non variable voltage KGO (like from hoosier or whatever) then I can guarantee you that as long as the charger has the output I mentioned above (usually found on the flat part where you screw in the battery, on a label) that you 100% do not need a new charger.
If you have a KGO VV it seems that it would have come with a micro USB cord so that's pretty much impossible that you have one based on my deductive reasoning.
Never charge your batteries unattended or while you are sleeping. Getting a li-po charging bag is always a good move.
HobbyKing has them for like 2 bucks. $2 will take all the danger out of charging batteries, but you should still always charge them nearby where you can react if there's a problem.

If you would like to learn more about batteries, but can't spend the (exorbitant amount of) time reading through Battery University like I did, you can click on the link in my signature and hit Control+F and type in Batteries 101 and get the crash course from my Vaper's Handbook.
