One new incoming gadget was an LG mobile phone. As it happens, we
already have an LG charger in the house from another (now stolen) model:
they look physically identical and have the same proprietary jackplugs.

The old wallwart says it puts out 4.8V / 0.9A; but the new one is 5.1V /
0.7A (ie higher volts but lower current).


My suspicion would be that neither are as accurate as stated - but can you put a
meter probes into the connector of the old one (off load) to check if it really
is 4.8v?
The lower (if it is) voltage should not cause any damage and the current
available is slightly more than required but again no damage likely.

If the unloaded output voltages are exactly as stated then it is /just/ possible
that battery would not charge fully - but my bet is that there would be no
difference.
Try a google for the phone model number (and charger) to see what amazon/ebay
etc offer as replacement chargers for that model.
