## NiMH Battery Charge Time Calculator

### Estimated NiMH Battery Charging Time Table

Battery Capacity (mAh) | Charger Output (mA) | Estimated Charging Time (Hours) |
---|---|---|

1000 mAh | 200 mA | 7 hours |

1000 mAh | 500 mA | 2.8 hours |

1500 mAh | 200 mA | 10.5 hours |

1500 mAh | 500 mA | 4.2 hours |

2000 mAh | 200 mA | 14 hours |

2000 mAh | 500 mA | 5.6 hours |

2500 mAh | 200 mA | 17.5 hours |

2500 mAh | 500 mA | 7 hours |

3000 mAh | 200 mA | 21 hours |

3000 mAh | 500 mA | 8.4 hours |

### Key Considerations:

**Battery Capacity (mAh):**The higher the capacity, the longer it takes to charge.**Charger Output (mA):**Higher output current means faster charging. Always use a charger rated for your battery's voltage and capacity.**Inefficiency Multiplier (1.4):**Due to heat loss and other inefficiencies, NiMH batteries typically require about 40% more energy than their stated capacity to fully charge.

You can use this table as a rough guide to estimate the charging time for different combinations of battery capacities and charger outputs.
