A handheld analyte meter, such as a blood glucose meter, has a measurement module, a rechargeable battery and a charging control to select a maximum charging current to regulate self-heating during recharging that can interfere with analyte tests. Self-heating by the meter can bias temperature measurements made inside the meter that are used to determine whether the temperature is acceptable for testing. Prior to beginning a charging session, the charging control selects the maximum charging current that does not change during the charging session based capacity of a charging source along with a first temperature measured near the battery that is compared with a first temperature range. By selecting the maximum charging current in this manner, the risk of the measurement module preventing a test under high lock-out conditions and the risk of the measurement module allowing a test when low lock-out conditions that are masked is reduced.

Handheld analyte meter with recharging control for improved analyte testing

A portable handheld medical diagnostic device capable of communicating with an external device and a method thereof are disclosed. The device has a protective enclosure, a main circuit board provided in the protective enclosure and having a wireless connectivity component and a controller facilitating a physiologic measurement and communications of results of the physiological measurement to the external device. Also provided in the protective enclosure is a mezzanine circuit board having at least one of a plurality of additional feature modules and a universal connection interface programmed to both facilitate operation of the additional feature module and operate under the control of the controller as a control interface between the controller and the additional feature module.
