charge when battery considered full/empty at given conditions (temperature,
age)". I.e. these attributes represents real thresholds, not design values.
+ENERGY_FULL, ENERGY_EMPTY - same as above but for energy.

CHARGE_COUNTER - the current charge counter (in µAh). This could easily
be negative; there is no empty or full value. It is only useful for
relative, time-based measurements.
+PRECHARGE_CURRENT - the maximum charge current during precharge phase
+of charge cycle (typically 20% of battery capacity).
+CHARGE_TERM_CURRENT - Charge termination current. The charge cycle
+terminates when battery voltage is above recharge threshold, and charge
+current is below this setting (typically 10% of battery capacity).

CONSTANT_CHARGE_CURRENT - constant charge current programmed by charger.
CONSTANT_CHARGE_CURRENT_MAX - maximum charge current supported by the
power supply object.
-INPUT_CURRENT_LIMIT - input current limit programmed by charger. Indicates

-CHARGE_TERM_CURRENT - Charge termination current used to detect the end of charge
