1 BBIt was fixed <| sep |> Hope it ' s not just because it ' s a contract year . <| sep |> As a battery discharges the voltage drops . So if the battery is rated at 15 V then when it ' s half empty it might give only 14 . 5 V . It a bit more tricky than that , because it ' s not exact . So there ' s a little controller which monitors the usage and the power drop and sees when it cuts out . That ' s why sometimes if you let a device go completely empty the power remain seems to act very different . Charging is the other way round , as the battery gets fuller the voltage goes up meaning it ' s harder to keep charging . <| sep |> I have used Dayna ' s Pet Sitting for my cat as well . Also a very satisfied customer ! <| sep |> so youre suggesting that since this revenue stream won ' t solely pay for all of the projects , we shouldn ' t use it to pay for any of the projects ?
