One of the most frequently asked questions we receive
is: Will the BLS work on my battery?
Our answer is good news. The Battery Life Saver electronic
device is suited to work on all types of lead-acid batteries. Simple
or complex, they follow the same basic principles. Whatever industry
you are involved with, there is a BLS market in your area for other
applications, a myriad of other potential customers.
We do not endorse any
particular type of batteries. The statements in this article are
intended only to give a general briefing about types of lead-acid
batteries and possible applications where the BLS can be used.
Types of Lead-Acid Batteries
There are
two types of lead-acid batteries. There are starter (or cranking)
batteries that can generate a high amount of energy in a short
period of time. These batteries are commonly used in vehicles to
start the engine.
There are also deep cycle batteries. A deep cycle battery can
generate a smaller amount of energy for a longer period of time.
Deep cycle batteries are constructed with thicker plates and can
withstand a deeper discharge, making them more prone to sulfate
build-up. These batteries are commonly used in golf carts,
forklifts, RV’s (for the house batteries), off grid solar systems,
Uninterrupted Power Source (UPS) and electric chairs.
Besides the 2 types of lead-acid batteries, there are also different
versions where the lead is mixed with other metals or it is used in
a purer form. This alters a bit how the charge or discharge of the
battery happens. There are also hybrid batteries that have
properties of starter and deep batteries. Despite all complexities
that can be found to increase or modify performance, a lead-acid
battery is a lead-acid battery.
Common Battery Technologies
No matter if batteries are starter or deep cycle, the two most
common technologies are Flooded and VRLA (valve-regulated
lead-acid), most commonly called Sealed lead-acid batteries, The
VRLA is divided further into Gel and Absorbed Glass Mat (AGM).
Wet cells or flooded batteries are the most popular. They are used
on cars, boats, golf cars, solar and wind banks. The marine type is
not sealed so users can refill any water that was lost while
charging. Special care should be taken while operating any non
sealed batteries; first to prevent getting burned with the acid
solution inside the battery (follow the safety instructions and use
safety gear) and second to prevent the battery from getting
contaminated with external agents (sea water, rain water, soil etc).
Non-sealed batteries are not the strongest, mechanically speaking.
They crack easier than others. Make sure to fully charge them before
a long winter. Even better, charge them at least once a month during
the winter months, as you run the risk of battery cracking due to
freezing. We will cover winter battery maintenance in the next
issue.
VRLA (valve-regulated lead-acid) You can not refill these batteries.
They are designed against spills.
Gel Cells: The electrolyte is mixed up with a jellifying
non-reactive agent like fumed silica that immobilizes the
electrolyte. If for any reason the battery cracks, the cell will
continue operating. You cannot use just any charger to charge gel
cell batteries as you can ruin them easily by overcharging. These
kinds of batteries require lower charging voltages compared to
flooded batteries. Read the instructions on charging to get the most
of these batteries.
Absorbed Glass Mat (AGM): This kind of battery uses a glass mat to
contain the electrolyte. They are basically spill-proof compared to
the flooded type. Mechanically speaking, AGMs are the strongest
batteries on the market. Although very similar to the charging
voltages of the flooded batteries, you still need to be careful
while charging, as overcharging can shorten their useful life
dramatically. The AGM offers a long list of advantages like shorter
charging time, resistance to vibration, continuous operation even if
the container cracks or breaks, lower self discharge than other
types (around 3% per month vs. 1% per day on flooded cells), low
energy conversion into heat (around 4% vs. 15 to 20% on flooded or
10 to 16% of the Gel cells) and minimal fume production. On the
other hand, they are 2 to 4 times more expensive than the flooded
batteries.
VRLAs are favored by owners
of boats, electric scooters, golf car and Neighborhood Electric
Vehicles (NEV). AGMs are particularly favored with off grid solar
and wind systems as well by RVs, aviation and jet skis. There is one
more emerging market to be aware of; truckers are starting to use
deep batteries to power their small refrigerators, AC/heat units or
ovens, due to the recent anti-idling legislation.
In summary, you can use The Battery Life Saver electronic device
with all applications mentioned.
