Common Questions
Is this a good choice for smoke detectors?
If the battery is a backup to household power, a standard heavy duty is best, and also much cheaper.
I want to know the mah rating of these.
There are charts of their website for specifications and usage, but no MaH.
What is the last date of expiry?
I use them for the backup battery in my ac powered smoke detectors and 2 clock radios, the previous batches were still strong after they expired.
How many Amps are there?
It is almost identical to coppertop with a discharge rate of 100 mAH.
What is the expiration date if you bought it today?
The battery's lifespan will be the same as in stores that have a normal turn over time of about 15 minutes. This can be from 3 to 5 years in the future.
