Parallel connection on lantern batterys will have higher current, but it wi ll cause self dicharge to other battery with lower voltage. My solution to solve this problem was to add one diode to each battery, but I do not know why this method was not used on commerical battery pad ? Can any members of this group give me me advice. Thank you and happy x'mas to all members.

Diodes have a forward voltage drop. Depending on the diode type and current the loss may be as much as half of a cell voltage. The diode also dissipates power which isn't generally a good idea buried in a battery pack. If the cells are identical (cells manufactured at the same time, on the same line, are close enough), isolation isn't worth the loss in useful energy.

Not usually true; the exception, is if your cells spontaneously develop short circuits (like whiskers in NiCd or bent plates in lead-acid). Discharging a battery cell, ideally, raises its internal impedance, doesn't cause leakage.

Diodes have significant effective resistance, it lowers the voltage and current the battery can deliver.
