What's with Aqara's phobia to AAA and AA batteries?

All the battery powered devices seem to use either coin cell or some other less common battery type. Aside from size, is there any other practical reason why they avoid the common battery types where rechargeable options are plentiful?

Batteries are the basics, but you can also use a rechargeable battery. This is the most convenient and common type.

Unfortunately they offer way more battery life in way less space. With rechargeable AAA they would not be able to advertise sensors with 2 to 5 years battery life.

  • One rechargeable AAA can deliver 1.2 V x 750 mAh = 900 mWh.
  • One small CR2450 3 V x 600 mAh = 1800 mWh (two times the energy of one AAA).
  • One CR123 3 V x 1550 mAh = 4650 mWh (five times the energy of one AAA).

However, I like IKEA strategy which now uses rechargeable AAA in all their sensors and buttons. They are larger and heavier of course, for wireless buttons it doesn’t matter, for that motion sensor in the corner maybe you prefer something less bulky.

I prefer AA or AAA because I can recharge them… ThirdReality is in a good path on that…

Smaller sized devices.

Hello @BigMacCombo
CR batteries have proven themselves to be reliable and trouble-free. AA and AAA batteries require a redesign, and CR batteries were chosen due to their size and superior design.
