Battery ratings explained

August 8th, 2014

There can be some confusion when purchasing a new battery, I hope to clarify some of the terminology used here……

Depending on the application the 2 important ratings are AH (Ampere Hours) and CCA (Cold Cranking Amps.

AH is important to know when you are buying a battery for cycling, i.e.. running a fridge or light in your caravan, motorhome or camper.

And CCA is the important rating for start batteries that are required to start the engine in your car.

Cycling or Deep Cycle batteries
These batteries are available in lead acid, sealed lead acid (SLA), AGM or Amalgamated Glass Matt, Lithium and are designed to be cycled between Full and the minimum cell voltage, which is usually 2.0v or 12Volts for a 12 volt battery. Now I know you can use them below 12 volts but for battery health and longevity consider 12 volts as a minimum.

A Rule of thumb for a battery not on charge is:
12.75v – Full
12.50v – Half
12.25v – Empty

Start Batteries
Start Batteries are usually lead acid, Calcium (Still lead acid but with a calcium component in the plates), AGM.

What is AH (Ampere Hours)?

The most common battery rating for cycling batteries is the Amp-Hour rating. This is a unit of measurement for battery capacity, obtained by multiplying a current flow in amperes by the time in hours of discharge. (Example: A battery which delivers 5 amperes for 20 hours delivers 5 amperes times 20 hours, or 100 ampere-hours.) 20 Hours is a standard discharge time that has been adopted by most manufacturers for AH rating.

What is CCA (Cold Cranking Amps)?

The industry recognised standard for defining starting power is Cold Cranking Amps (CCA). The battery’s ability to perform is measured by the amount of current the battery can deliver at -18°C over 30 seconds, while maintaining a voltage equivalent of 1.2 volts per cell or higher.

What is RC (Reserve Capacity)?
The Reserve Capacity (RC) rating represents the number of minutes at 26.7°C (80ºF) a battery can supply a load of 25 amps and maintain a voltage of 1.75 volts or higher per cell (10.5 volts for a 12 volt battery).

Higher rated CCA batteries will last longer and perform better in all vehicles than a lower CCA rated battery.

We sell Century batteries are guaranteed to exceed the CCA rating advertised on the battery, while some other manufacturers only claim to be within 10% of the rated capacity as required by the standard.

Battery Chargers

July 2nd, 2013

Coffs Harbour Auto Electrical Uses and recommends Projecta battery Chargers. Project offer a great range of well built and well featured battery chargers.
What to look for in a battery charger?
There are a lot of options when it comes to chargers, here are some of the feature we think are essential and the reason why:

  • Sturdy Construction – for mobile applications like caravans, camper trailers or motor homes it is important to have a easily mountable and sturdy case to meet the mobile environments demands
  • Multistage charging – Batteries really are quite fussy when it comes to how they are charged and maintained. This is the difference between getting good battery service/life and suffering a battery failure while on the road. Minimum of three stages (Bulk, Absorption and Float) is required extra stages such as rejuvenation and maintenance are nice features to have.
  • Ability to limit charging current – This is critical with AGM batteries as too high a current can prematurely end a batteries life if let run flat. This also means the charger can be run below its maximum output reducing heat and noise.
  • Temperature sensor – It is critical to monitor the battery temperature while charging as battery temperatures significantly affect battery life
  • Clear Display – The ‘perfect’ battery charger should have a clear display and an easy to use menu. Our Recommend charger also has a remote display that can be mounted in a convenient spot inside the Caravan or Motor Home.

We recommend the Projecta IC2500 Intellicharger for most applications upto 200 Ah, This Charger has a maximum sustained and continuous output of 25 Amps, it is a 7 stage charger with ability to control maximum charging and has a range of battery types to select the correct charging cycle, it comes with a clear and easy to read LCD display and an intuitive and easy to use menu(we setup the charger for you if we install it). Also available is a remote face that can be installed in a convenient place.

How Reversing Cameras & Parking Sensors Protect Your Car

How Reversing Cameras & Parking Sensors Make Your Car Safer

Reversing cameras & parking sensors are a great addition for the driver who takes pride in parking a car properly and accurately while also preventing possible collisions. Parking systems are available as either camera/monitor combinations, or as proximity sensors. There are many different types of camera systems each with their own pros and cons. Parking sensors are basically grouped into 2 types and can be fitted to any vehicle with a plastic bumper.

Drivers of all vehicles on the road will benefit from any one of these systems and many coroprate and government fleet managers are becoming increasingly aware of the benefits. With increasing media focus on four-wheel drives and the number of passenger cars with poor visibility, it is no wonder that assisted parking systems are becoming increasingly more popular.

Let’s take a look at the differences between the various systems on the market.

Camera systems.

As mentioned above, there are basically 3 types of systems.

Stand-alone monitors and camera combinations are fitted on the dashboard or the windscreen usually with a full-colour, TFT LCD screen in a variety of sizes. For example, a 4 inch screen will suit most passenger vehicles, utilities vans and four-wheel drives and these work in conjunction with a mini camera fitted under the boot lid or number plate light.

The larger screens of around 5 to 7 inches are more suitable for trucks, buses and motor homes and are usually fitted with a larger commercial grade camera.
All systems offer at least 2 inputs for multiple cameras allowing you to have a camera at the back of the vehicle as well as behind a caravan or boat.

Rear-view-mirror-monitor and camera combinations incorporate a built-in LCD screen. Although these are available as a clip-over or replacement, most safety-conscious suppliers will recommend a replacement, because clip-over types may become dangerous in the event of an accident. It is common for existing mirrors to be removed and the replacement unit fitted using the existing base.

After fitting, the mirror operates normally and is very neat and has a factory fitted appearance. As with camera units, most models offer at least 2 inputs for multiple cameras so that you can see behind a boat or caravan.

Integrated camera systems are vehicle specific and use the existing factory-fitted colour screens fitted in some cars. They are usually used in conjunction with a mini camera under the boot lid or number plate light and require integration hardware depending on the vehicle. Integrated camera systems are the neatest option and work hand in hand with existing in car technology, although they cannot be fitted with a 2nd camera.

Parking sensors.

Parking sensors are available for both front and back of the vehicle or both if you choose. There are two types of systems available, audible or audible with LED distance display. The units operate by utilising 4 sensor heads fitted into the bumper bar. They can be fitted to any vehicle with a plastic bumper and are therefore especially suited to all passenger vehicles.

They can be colour matched to take on a factory-fitted look at an additional charge.

So if you want to know more or ask about any of the 3 types been fitting to your car, bus, motorhome, ute, truck or something else u want, come in to Coffs Harbour Auto Electricial when we are willing to help you pick the right one for you and help as much as we can and give you a price in saving you from them little accidents like running in to a pole that u didnt see, or over your kids bike in the driveway.

Coffs Gets WRC round

September 30th, 2010

Woohoo!!

SYDNEY — Rally Australia, part of the FIA World Rally Championship, will relocate to Coffs Harbour in northern New South Wales from 2011, organisers said on Thursday.

The Confederation of Australian Motor Sport said the new location, 530 kilometres (330 miles) north of Sydney, would offer WRC competitors and manufacturers some of the most exciting and spectacular rally stages Australia could offer.

I reckon this is great news for Coffs Harbour, both Business and Public will benefit.
Heaps of publicity for Coffs tourism, funding for roads, input of funds from motoring bodies.

All round Great news, Well done Coffs!

Solar for Caravans and Motorhomes

September 30th, 2010

Coffs Harbour Auto Electrical has spent some time and effort researching and installing solar setups on caravans and motorhomes.

The Basic Setup

In our opinion a reasonable set of requirements for the majority of Caravans is,
1 x 100AH Deep Cycle Battery (Remember it must be sealed unless you have a sealed and vented battery box)
2 x 80 Watt Solar Panels
1 x 20 Amp 3 Stage Charger 240 Volt
1 x 20 Amp 3 Stage Charger 12 Volt
An Alternative to the 12 volt battery charger is :-
1 x Smart Battery Isolator so the caravan battery can be partially charged from your veheicles electrical system

The Facts

The most common request we get is “I need an extra battery for my caravan”, really the question should be “how can I better charge my caravan battery?”……

Fact – Most caravans do not have adequate facilities to properly charge a deep cycle battery.

The Ideal Solution

The ideal solution to charging your battery really comes in 3 distinct parts;
1. Charge the battery while driving
2. Charge the battery when connected to mains power
3. Charge the battery from the sun

Redarc (yes, we love Redarc products :)) make an excellent product to acomplish this, the BCDC1220 is a Battery Managment System or BMS, that accepts inputs from your 12 volt car or motorhome, the 240v mains when you are at a caravan park or running on generator and also has a built in solar controller. The BCDC1220 is a fully automatic 3 Stage battery charging solution that is selectable for Wet, Gel, AGM and Calcium Batteries. The Redarc BMS also monitors your battery useage/charging and displays estimated battery status on its remote mounted LCD Screen.
We believe that the best feature of this product is that it automatically selects the best input for charging, this means that the unit is “set and forget”. Nothing to switch on or off, no boiled batteries and best of all a charged battery when you need it!
We have bundled a some Solar Packages that include the Redarc BMS, Solar panels and cable etc.
