No.NiCd/NiMH - I can trickle charged at c/10
Energizer, panasonic and other manufacturers say that a Ni-MH cell should be trickle charged at only C/40 so that they last a long time.
No.I have 4 AAA NiMH 1100mAh, so I should find a charger with ~110A?
110A will melt the wires and the battery will disappear in a loud BANG!
Only if the battery is completely dead. C/10 will over-charge a fully charged Ni-MH battery (but is OK for an old Ni-Cad battery).1100 x 10% = 12 hours
You should have a circuit that shuts off when it senses that the battery is fully charged.
Sooner or later you will try to over-charge a battery that is already charged and your extremely simple high current circuit will blow it up.For an 1100mah 2/3 A it says I can do a 500mA max peak charge rate? Is this safe if I know the batteries are fully discharged (or < 10%) and only charge for 1 hour?
You should use a battery charger IC that has been designed by experts. It senses that a battery has some charge then reduces the charging time to avoid a problem. It properly shuts off when the battery is fully charged.
