Is there a significant difference in the way alkaline and rechargeable Li-ion discharge while being used? My standard battery scanners include HP1, HP2, 396, and 436. All use rechargeable Li-ion batteries.
I ask this because I recently bought a Qardia blood pressure monitor. It uses 2 AAA batteries in the sensing unit (cuff) and sends the results to my Android phone via Bluetooth. I sent an inquiry to their company asking about the efficacy of using rechargeables. Their reply said
There are two reasons we do not recommend rechargeable batteries be used with the QardioArm:
1) Physics - The way rechargeable batteries release current is different from that of alkaline batteries.
2) Regulatory - There are different regulatory standards (not harder, not easier, just a different set of standards) a device has to comply with to operate with rechargeable batteries.
Are they blowing smoke or is this really a serious consideration?
