More probably it is a matter of insufficient voltage - Lithium and
alkalines typically start their discharge curve when new about 1.6 or 1.7
volts. NiMH about 1.3 to 1.4 volts. The old Nickle Cds were even lower -
typically 1.25 volts. The external battery can't charge perhaps if it is
below 1.5 - just a guess, though.

Spring has sprung, the grass has riz. Wonder what kind of grass it is?
