How to fill a Basement Watchdog Standby Battery

[ddenuci]

My Watchdog Battery 24EP6 performed admirably during Hurricane Irene. However, it did die within about 4 hours of continuous pumping. (It is rated for 6 hours). Fortunately, I was able to replace the 24EP6 with a car battery. Now I'm trying to recharge the 24EP6. Anyone know how long it typically takes to recharge under these conditions? The alarm is on continuous - cannot be shut off by pushing the reset button.

@ddenuci According to the watchdog documntation: It depends on the size of the battery and the sump pump system that is doing the charging. The chargers on the Basement Watchdog Special and Emergency systems are less powerful trickle chargers, and they will take several days to recharge a battery. You could take the battery to a service station for a quicker charge, or hook the battery up to an automotive charger if you have one.

@ddenuci Should have also mentioned that I needed to add some water to two of the six cells. Not much, but it was the first time I added water in the three years that I had the battery. Again, according to the documentation, I should have been checking it every 9 months to see if it needed distilled water. Note: When refilling the battery cells, do not use the sulfuric acid that was used initially. Only use distilled water.
