Each battery box sold says 4, 8, 12, 24 pets for 7 days depending on the battery size.

The notecard in the free autopetter says:

"Freq..." allows you to choose how many times per day you want it to pet your meeroos.
The higher the frequency, the faster your Meeroos will gain regard, but also drain the batteries .

Does this mean if I buy a 24 pets per 7 days battery (595L one) but set my autopetter frequency to 8 pets per day my battery will last 21 days instead of 7? 24pets/8pets = 3 times slower so battery lasts 3 times longer 3x7 = 21 days?
