Keyless entry remote battery

Hi,
My remote key batteries died and I see that the batteries in it were
Panasonic CR1620.
Just want to know if I can use Panasonic BR1620 batteris instead, since
I'm unable to find the CR1620 model in a local store (even in the case
of the BR1620, I could get an equivalent in another brand, but not
Panasonic).
Any suggestions would be helpful.

Thanks,
keychey.

Well, for the few bucks it'll cost you to conduct the experiment, it's
probably worth a try in a pinch, and it'd be a benign experiment as well (you
won't hurt anything if it doesn't work out).

The BR1620 and CR1620 are physically identical and provide the exact same
Nominal Voltage, but they use different chemistries, tuned for different
applications. They therefore exhibit different characteristics, a key one
being Operating Temperature Ranges, with the BR series extending the high temp
limit by 20°C over CR series.

If that was all there was different, you'd be good to go, but there are more
significant differences, with the key one being Continuous Drain (BR = .03mA,
CR = .10mA) which means the BR can only provide 30% of the current of the CR
when you push the button on your key. The effects of this could range from
virtually nil to reduced range to total lack of function, depending on how
much power the key transmitter actually demands to do its job.

Thanks for the information, appreciate that. Saw a CR1620 model by
Radio Shack (not Panasonic) being available in a nearby store. Will try
that out tomorrow and see how it goes.

Thanks again,
keychey.

Those CR1620 batteries from Radio Shack worked just fine, just had to
re-program the remote after replacing the old ones.
