Batteries ain't Batteries
Ever wondered why lead acid batteries don't seem to last in your boat
and always fail when you need them the most? Remember the time when cars had generators
and the batteries only lasted 2 years at most? Why after 150 years of lead acid
battery development it appears you can't buy a decent long life battery
Well the answer to all these questions is simply all Batteries ain't
In fact there are many different types of Lead Acid Batteries; Starter Batteries,
Standby Batteries, Traction Batteries, Remote Area Power Supply Batteries, Load
Levelling Batteries, Electric Vehicle Batteries and Solar Batteries to name just
a few, and they are used in emergency lighting, telecommunications, Un-interruptible
Power Supplies (UPS), Navigational Beacons in fact in applications where the reliability
and long life of the battery are high priority features.
Lead Acid Battery technology has undergone major changes over the past 20
years resulting in high quality long life batteries tailored to specific applications.
In fact that is the culprit in most instances why the batteries you use in
your boat fail prematurely; YOU ARE USING THE WRONG BATTERY! A battery that has
been developed to meet a specific application will not perform well when used
in a different application. Makes sense?
In most Boating situations you probably have at least two different applications
as different as chalk and cheese. Namely batteries designed to start a motor (high
discharge current for a couple of seconds) are not designed for the long slow
discharge requirements of Marine Batteries (House Batteries). Remember that these
days Marine Batteries are used more and more for Navigation Equipment, Entertainment
equipment, lighting, refrigeration, autopilot etc. No longer are batteries just
Lets explore the physical Chemistry of this as to understand is to know and
to know is to make the right decision.
For simplicity sake lets compare a starter battery load profile with that
of a marine battery.
|| Starter Battery
|| Marine Battery
| Discharge Current
|| +/- 10A
| Discharge Time
|| 10-30 seconds
|| +/- 5 hours
|| Immediately (seconds)
|| After some time (hours)
| Depth of Discharge
per (starter) cycle
| Around 1%
|| Maybe as high as 50%
It is obvious that there is at least an order of magnitude difference in the
requirements between these two applications.
In the case of a lead acid battery the current (electrons) comes from an electrochemical
reaction between the Acid (electrolyte, H2SO4) and the Positive Plate (PbO2, Lead
Oxide) and the Negative Plate (Pb, pure lead). The electrons are emitted by the
Is there hope for Boaties?
To tell you the truth!.........Yes, and its Australian Technology.
Developed by Battery Energy Power Solutions in conjunction with the Novel Battery
Group of the CSIRO.
The CSIRO is recognised internationally as the world leading expert on lead
acid batteries. They have been testing every type and make of battery for many
years and understand the major failure modes. They have designed batteries for
every conceivable application and for major corporations such Pacific Gas and
Electric (USA, Utility for load levelling) and General Motors (USA, electric Vehicles)
as well as for a number of major overseas battery companies, such as Hawker and
Battery Energy is a specialist industrial battery manufacturer, Australian
owned and operated and based in Sydney. Working with the CSIRO they developed
a unique battery in 1992 and launched it onto the industrial market in 1997. Needless
to say that the CSIRO has tested this unique battery exhaustively and Battery
Energy and the CSIRO are able to back every claim they make.
OK, what is this battery?
MARINEGEL is a range of Sealed Gel Batteries suitable for marine applications
as a starter and or house battery.
It is unique in that:
- As a Gel battery it has been designed to be charged by standard battery charging
regimes as found in most marine and automotive applications (alternator on diesel
etc) unlike other sealed batteries that require specialised charging regimes
- The gel overcomes the problems of stratification and sulphation as the electrolyte
is trapped by the gel and cannot stratify - a problem with other types of
sealed batteries such as Absorbed Glass Matt (AGM)
- It is much less prone to thermal runaway (having been tested extensively
at elevated temperatures between 40 and 60 degrees), than other gel batteries.
AGM batteries have an even greater problem in this respect
- It has an extremely long cycle life more than 1,200 cycles to 100% depth
of discharge (more than 5,000 cycles at 25% depth of discharge @ 25 degrees C)
this means more than 10 years real operational life in practice
- Under float application it has a design life of > 20 years
- As a sealed battery it can be installed on its side, is acid spill proof,
fire and explosion proof and requires no special ventilation. This alone differentiates
it from virtually every other battery in the market. Unlike flooded batteries,
it can be transported as non hazardous cargo
- At end of life it is totally recyclable
- It is much more tolerant to overcharging than other sealed batteries
- It has a low self discharge rate
- It is the most efficient Gel Battery in the world in that
it requires only 102% energy recharge to reach 100% state of charge
- From independent tests in America the MarineGel battery has been shown to
be twice as cost effective as its nearest battery competitor
- It can be recharged back to 100% capacity very quickly
- It can provide High Cranking currents suitable for starting diesels, although
it is not as good as thin plate AGM or car battery types
Positive plate thickness compared to cycle life
With this information I trust you will be able to make an informed decision
as to what is the correct type of battery to install on your boat to ensure safety,
reliability and the security of battery availability under all extreme conditions
Remember Batteries Ain't Batteries.
