I have a battery charging circuit with an ic of max712, It is capable to charge Nickel Metal hydride(NiMH) and Nickel Cadmium(Nicd) type of batteries. Shall I Connect Lithium Ion Battery with this charging Circuit?...I have a confusion because every charging ic will specifying supported type of battery. Basically CC/CV is the charging principle then why charging ic will not supporting all type of batteries.
I think it depends on the charging rate, for example some are C/1, some C/3 (perhaps the MAX712 can't be configured for Li Ion charge rate?), and possibly other issues. I hope either of these documents is helpful:
if you want to charge lead acid batteries, then use alead acid batteries charger. The MAX712 is no lead acid batteries charger.
Maxim has a lot lead acid batteries charger ICs.
The gist of all this is that you should use a battery charger only for the type of battery it is designed for.
Each type of battery has its own requirements for proper charging, and trying to charge a different type of battery can result in battery failure or even an explosion and fire if it's a lithium-ion type.
