I'm looking for a relatively small rechargeable battery to power a small timer circuit.
An LIR2032 *looks* ideal for my purpose on the face of it (typical rating 40mAh), but I'm trying to understand exactly what the spec means by "max pulse discharge current" - which is typically given as 70 or 75mA for this type of battery.
I guess this means it can sustain a short duration current discharge significantly greater than it's continuously rated discharge current, but surely there should be time/cycle information quoted? If not, is there any rule of thumb?
In my case, my circuit draws <1mA when sleeping so no issue there, but every 1-5 minutes (adjustable), it switches on a mobile phone vibration motor and a small buzzer for a period of 5 seconds (total current 70mA).
Thanks!
