Sealed Lead Acid Batteries (SLA Batteries)
The basic lead acid battery has been in use for over
100 years. Today's batteries have an average life of
12 to 36 months, although some may last up to 48 months
depending on environmental conditions and usage.
SLA Batteries - Replacement UPS Batteries
UPS systems (Uninteruptable Power Supplies) use SLA
batteries as power back-up in the event of a power failure.
A variety of sizes are used, most commonly ranging from
6 volts to 12 volts, and 2 amps to 75 amps. Listed below
are some common configurations:
6 volt, 5 amp (6V 5A)
6 volt, 12 amp (6V 12A)
12 volt, 5 amp (12V 5A)
12 volt, 7 amp (12V 7A)
12 volt, 12 amp (12V 12A)
12 volt, 18 amp (12V 18A)
12 volt, 26 amp (12V 26A)
12 volt, 33 amp (12V 33A)
Please see our battery page
for a complete listing as well as dimension. APC
UPS are among the most common found on the market. Their
lines consist of AP Series Ups, Back-Ups and Smart-Ups
to name a few. APC refers to their battery packs by
RBC numbers. Many of the RBC numbers contain a single
battery, while others consist of numerous batteries
daisy-chained either in parallel or in series. For example,
the RBC2 consists of a single 12V 7amp battery and the
RBC7 consists of two 12V 18amp batteries. We do not
supply new cable harnesses with our batteries. The existing
hardware should be reused.
How a Sealed Lead Acid Battery Works
A lead acid battery is primarily made up of lead plates,
sulfuric acid and water. The sulfuric acid and water
solution (electrolyte) causes a chemical reaction with
the lead plates to produce electrons. As the battery
is used, the release of electrons causes the sulfur
to rest within the lead plates. When the battery is
recharged, sulfur is released from the plates and power
is restored to the battery.
SLA batteries are maintenance free over
the duration of their life and do not need to have water
added or the gravity of the electrolyte checked. SLA
batteries are constructed in a manner which ensures
no electrolyte spillage, therefore making them safe
for transfer and operation. In the instance that gas
pressure builds up in the SLA battery, vents located
on the top of the battery release the gas and automatically
reseal once the pressure returns to normal levels.
SLA Battery Usage
Sealed Lead Acid batteries have many uses and can be
found in a variety of products and industries. Here
is an example of some common usages:
Uninteruptable Power Supplies (UPS Systems)
Emergency Lighting
Home Security Alarm Systems
Septic Tank Systems
Medical & Instrumentation Products
Telecommunication Systems
Children's Battery Powered Riding Cars
Motorized Scooters
Battery Failure
Eventually, batteries need to be replaced because they
can no longer hold a charge. One reason for battery
failure is because over time sulfur builds up and coats
the battery's lead plates. This is called "sulfation
build-up". Another reason for battery failure is
caused by corroded lead plates. The corrosion of the
plates does not allow the chemical reaction to take
place, therefore no electrons are discharged.
