I am busy designing a AA NiMH battery charging circuit, and basically they are being trickle charged. However to meet IEC 60950 I believe we have to test the charge current with a shorted cell and a one fault in the charging circuit. Does anybody know what the maximum charge current can be before the batteries become dangerous. My circuit currently limits the current to 300mA but I cannot find any data on what is the maximum safe continuous charge current for a rechargeable battery.
