The battery and some plumbing pieces are sold separately. However, they are specialty batteries and often cost much more than the Wet Cell plus, they may require a special charger.īackup sump pumps often are sold as complete units and contain most of the necessary parts, including a charger.
These are important considerations because the battery will be located in the basement, which often has higher humidity than outside air.
The Gel Cell and AGM are preferred for backup sump pumps because the plates do not sulfate easily, the terminals don’t corrode and the chance of a hydrogen gas explosion occurring is small. Some versions of the lead-acid battery that you may find in stores are the Wet Cell, Gel Cell and Absorbed Glass Mat (AGM). However, for backup sump pumps, this type is not as preferable as a deep-cycle battery. The AH rating usually is printed on the top of the battery.Ĭombination 12-volt lead-acid batteries have a CCA and an AH rating. For example, if a battery has a rating of 80 AH, it would provide 4 amps an hour (80/20) for 20 hours. The standard AH rating indicates the number of amps provided in excess of 20 hours. This type of battery is rated in ampere-hours (AH). This is not the type of battery to use with a backup sump pump except in an emergency.Ī deep-cycle lead-acid battery (sometimes called a marine battery) is recommended for backup sump pumps. The number of CCAs often is printed on top of the battery case. The output and capacity of these batteries are rated in cold cranking amps (CCA). These batteries are designed to provide a large amount of current for a short period of time. Most people are familiar with the standard lead-acid vehicle battery used in a car. For further info please contact the Olmsted Township Fire Department at (440) 235-3746 or visit our webpage at /fire.Two types of lead acid batteries are available. It is also a good time for you to discuss and formulate a home escape plan that includes two exits from each sleeping area so you and your family knows what to do in the event of an emergency. You should also have a carbon monoxide detector on each living level, in the basement, and near (not inside) an attached garage. Keep in mind that smoke detectors have a service life of ten (10) years. The state fire marshal recommends that every home have a smoke detector installed on each floor, including in a finished attic, in the basement and in each bedroom.
We would like to remind everyone to check their Smoke Detectors and Carbon Monoxide Detectors and switch out the batteries in them when you change your clocks on November 4, 2018. For further information on sump pump maintenance, you can go to Along with this, keep the area where the battery is stored clean and clear of objects. Remember to always follow the manufacture’s recommendations. Regardless of which battery you have, keep in mind that all batteries should be checked regularly by someone who is knowledgeable and can test them to make sure they are working properly.
BATTERY BACKUP FOR SUMP PUMP FREE
The second type is a maintenance free battery and is called a gel cell (valve regulated or deep cycle) battery. Be advised that the more often your battery runs, the more often it will need to be filled. The lead acid (or wet cell) battery needs monthly maintenance and requires distilled water to be periodically added in order to keep water levels ½ inch above the top of the plates. One is a lead acid (or wet cell) and the second is a Gel Cell (valve regulated or deep cycle) battery. There are generally two different types of batteries that can be used on battery back- up systems for sump pumps. A picture of a sump pump with a battery back-up system is attached. Both of the batteries where tied to an electrical power source through an inverter/ charger to keep the battery fully charged. Lack of water in certain types of batteries may cause the cells of the batteries to overheat and off gas causing a hazardous condition as mentioned above.
The source of the gas release was due to little or no water in the batteries. In both situations, Carbon Monoxide and Hydrogen Sulfide gases were found inside the residences. The batteries were being used as alternate power sources in case the primary power source is lost. Lack of maintenance to the sump pump battery backups was determined to be the cause. The Olmsted Township Fire Department recently responded to two separate emergency calls where hazardous gases were found in the basement of residences. To the Residents of Olmsted Township Ohio
