One of my EzRobot battery is dead, can't charge
Do I just throw it away in the trash?
What other battery can be used?

Yes, batteries on Amazon are prevalent but there's no guarantee on if they will fit inside an EZ-Robot. We'll have to wait and see
My new batteries should be here tomorrow, I will try them out.
If they don't work, maybe Jeremie can get some and I will pay him :-)
Just a joke
Most DIY robot builders here understand voltage, polarity, JST connectors, C ratings etc but for the casual ez-robot user who visits synthiam forum, the use the manufacturer recommend battery is the way to go.
That's exactly right, I know the quality, dimensions, and connections of the EZ-Robot battery but I have no idea what else is out there. Most LiPo batteries these days also come with a yellow XT type connector so switching the battery connection back to Deans would be a scary process, as you could short out the battery leads with your soldering iron.
I have dealt with my fair share of puffy batteries but I have never had one catch fire or explode before. This is likely due to me taking care of the battery before anything negative happens. I know for a fact that there's no going back from a puffy battery, no matter how hard I tried to cycle charge them to bring them back. The battery chemistry is changed, oxygen fills the battery, and the capacity is quite diminished. The only thing left to do is properly dispose of the battery.
I would definitely recommend as the first course of action is to bring the puffy battery to a local recycling/disposal facility. But in the case that a place like that doesn't exist in your area, the following can be done:
When a LiPo puffs up it is best to drain it all the way down with a large power resistor (not too low in resistance - maybe 50-100ohms) or a 12V light bulb. You can even use the EZ-B itself by leaving it on to draw the voltage all the way down to nothing (it draws about 75-130mA depending on what you have attached). You don't want to drain it down too fast as it can still generate a ton of heat. Once the battery is depleted to 0V (test with a voltmeter) then you can short out the red and black leads. Then toss the battery in a ziplock and save it to bring it to a recycling/disposal facility in the town over the next time you visit.
*WARNING* Never ever short the battery leads unless you are 100% confident the battery is at 0V. If you short the battery wires while it has some charge left it's likely you'll witness flames and possibly an explosion.
*Edit Before you dispose of a puffy lipo, keep it stored in a flame-proof container. I use a crockpot, but there are containers and bags specifically designed for this kind of thing.
here's alink for the safety batt bags .

The vendor sent me a couple of replacements for free with the correct connector, and I have purchased since then and they were correct.

Edit. The one's @EZang lists below this post are a significantly better price.

If you need batteries, this is the correct one. I even charged it with the EZ robot charger
I had T connecters, dean, already from the past

After testing both batteries, I found out they both are good replacements. (No shipping charge)
