I am trying to understand the consequences (if any) of substituting a CR2450 battery for the specified CR2340 lithium battery in a small device. The device is constantly "on" and transmitting a signal, which is intended to be picked up by receiver based on proximity of the small device to the receiver. (When the small device is close enough to the receiver, a solenoid engages and stays on until the small device is again out of range.)
My hope is that -- because they have the same voltage and current rating -- the CR2450 will work and provide much longer battery life in the small device than the CR2430, but I just don't know enough to understand the impact of the specs that are different for these two batteries.
As mentioned, the CR2450 and the CR2430 have the same "nominal voltage" (3.0V) and the same "standard current" (0.2mA) ratings.
Physically, they are the same diameter (24.5mm), but different heights (CR2450 = 5mm; CR2430 = 3mm). [However, height won't be an issue here].
The difference in these two batteries' "nominal capacity" ratings (CR2450=600MAh; CR2430=270mAh) are the reason I hoped the CR2450 would last about twice as long as the CR2430.
BUT, they have different ratings for "continuous current (maximum)" (CR2450=1.0mA; CR2430=3.0mA) and "pulse current (maximum)" (CR2450=15mAh; CR2430=20mAh), and I just don't know whether or how either or both of those spec differences relates to this proposed battery substitution.
So can someone help me understand "continuous current (maximum)" and "pulse current (maximum)" with respect to batteries, and particularly how those spec differences might produce any practical differences if I substitute a CR2450 battery for the CR2430 battery that this small device was designed to use?
