Battery Charger. An unmatched battery charger can also lead to water loss.
Ohm''s Law confusion -
The voltage across the (ideal) battery is independent of the current through. That is to say, the battery is not an ohmic device and thus, does not ''obey'' Ohm''s law. In other words, the voltage across the (non-zero) resistance is fixed by the battery; that voltage is given and is independent of Ohm''s law.
