batteries may malfunction, it does not relate to a charger in any way. You can search Google for many explosions of iPhones, Samsungs, laptops and other mobile devices with bundled and certified chargers (Sony once called back a very large batch of laptops with faulty batteries exploding here and there). It just happens. Because some batteries are faulty. Like everything else can be faulty. Using low amp charger DOES NOT protect you in any way. Because lithium batteries do not drain power at a constant rate like nickels do. They need a lot of amps in the beginning and almost no amps at the end of charge cycle. If the chip inside fails to detect the current phase of charging, the battery will explode. Even at 10mA.
Chargers do NOTHING, they only supply energy. A special chip inside the battery takes care of charging. Lithium batteries are NOT like nickel based batteries.
While I understand chargers and that they shouldn't be much of a problem, you need to realize that if your battery doesn't regulate on its own, the charger DOES make a difference. The pic I posted is what happens when you use the wrong charger with an unregulated 'cig-a-like' battery. In this case, I used a .5amp charger from the same brand, but earlier version of battery, instead of the .4amp one supplied. The charger was plugged into a 2amp 120v to USB adapter for my Samsung phone. In this case I believe the charger fed the batt too much power @.5amps which caused the battery overheat and pop within 3-4 mins. Believe me, if you have an unregulated battery, the charger most definitely does make a difference. I only charge those batts on an adapter that is limited to .4amp now, instead of 2amp..
