Transformer question
In those situation where the charging transformer can be left plugged
in while the apparatus is in store (for example, a rechargeable electric razor) does the transformer "load" gradually discharge the battery? Hope not a silly question ! |

Hope not a silly question ! no. Is that "no it's not a silly question?" There will be a small leakage but generally will be insignificant to battery self leakage. |

Some chargers exercise the battery by completely discharging before re charging. Mike |

The amount of leakage in the charger is orders of magnitude lower than the self discharge of any battery NT |

Also reassuring, since having the charger/transformer permanently attached means it does not get mislaid or the wrong one used. (When are homes going to be 12(?) volt DC wired and we can forget all this paraphanalia ? Mobile phone chargers are going in the right direction - hurrah for the EU ! Now you don't often hear that ...) R. |

Hope not a silly question ! It's best not to leave chargers permanently plugged in to the mains. There is a small chance of overheat/malfunction starting a fire. |
