Then we insert externally a resistor R_ext (as if it were internal) in series between one terminal of the charger and the corresponding pole of the battery. On the other hand, perhaps we can check the validity of this 'internal resistance' idea for a charger by doing just the opposite as it follows:įirst, we find a good battery that the charger can charge it normally. Then we remove the resistor and notice how much the battery voltage drops (Vbat1-Vbat2): We measure the two voltages V_res on the resistor (R_ch) and V_bat1 on the battery. One easy method is to wire the battery as if we like to charge it via a resistor. If the charger refuses to continue charging the battery though its voltage is nominal then we can conclude that it detects its internal resistance (R_bat) first which usually increases with time. But if dissipation is not a problem (by using a power resistor or many resistors in parallel, series or both, to get R_ch), using 12V for example can let the charging current be rather constant while V_bat is increasing with time. R_ch = (Vcc - V_bat) / I_ch (worst case is when V_bat=0)įrom the formulas above it is better to choose a low Vcc to decrease dissipation (not higher than 5V). The charging current (I_ch) doesn't have to be high since we are not in a hurry :wink: This can be done via a resistor and a DC supply. 419, page 66.) Author Model page created. Price in first year of sale 139.95 Mentioned in Radio Shack Catalog (1988, No. Includes jacks for earphone, hand-mike, antenna and battery charger. If its voltage is too low then we should try charging it with a simple method till it restores its nominal voltage.

Sorry, I couldn't get your point on how to let the charger see the battery as having internal low impedance.īy the way, I supposed that measuring the voltage of the old battery gives a nominal value (for example like 1.2V or a bit less).
