Provavelmente não desde que as voltagens não são semelhantes. No link abaixo:
A Li Ion pack consists of a number of the series/parallel connected cells (typically from 4 to 16) to provide the required operating voltage and current levels. Nominal voltage of each cell is typically 3.6-3.7 V, the charging voltage is about 4.2-4.3 V per cell. The Li-ion phosphate cells have 2.9V nominal and 3.6V charging voltage. Note that because of the cell's relatively high voltage, many low-power portable products can operate from a single cell. Depending on the cell connection scheme, the nominal Lithium Ion battery voltage for a laptop computer can vary from 7.2 V to 14.8 V (typical voltages for major brands are: 11.1 to 14.8 V for Dell laptops, 10.8 to 14.8 V for Toshiba, Apple, Gateway and IBM laptops, 7.4 to 14.8 V for Sony, 7.2 to 14.8 V for HP, 14.4-14.8 V for Compaq). Note that the output voltage rating of a laptop power supply is not necessarily the same as nominal battery voltage.
