Abstract
A stationary battery testing device as provided for measuring imminent battery failure while the battery is in a float mode. The device includes a circuitry for measuring the internal resistance changes of a battery and then comparing them over a predetermined duration of time so as to provide audible or visual discernable signals to indicate an imminent battery failure after the expiration of said predetermined period of time. An additional temperature monitoring component may be provided for the device to monitor internal changes within the battery with respect to temperature. This can also be combined in a temperature compensated automatic adjustment of voltage and alarm thresholds in an active feedback loop to augment and broaden the basis of stationary battery applications where the battery testing device can be used.
