CR-1220 batteries.

Stupid battery sizes.  I like how most items standardized on AA batteries.

I wish they would do the same for the hockey puck batteries.  For the record, a CR1220 battery has 40mAh or about 1/75th as much as an AA, alkaline battery or 1/6th as much as a CR2032.


  1. I have to get out tomorrow morning and by a large pack of AAA batteries. I have plenty of AA, but for some reason, it triple-A this year.

  2. The question is what battery testing device is capable of delivering effective results for your needs. Maybe accuracy is your highest concern, or maybe you are looking for a fast and somewhat reliable system for your vehicle.
