What is the difference between a pure sine and modified sine inverter?

Both types of inverter will provide power to AC appliances, however Pure Sine is high quality equal to (or better than) the power in your home, Modified sine wave power is an simpler form of power and is adequate for simple electronics, but may damage more complex ones.

Inverters convert stored direct current(DC) power in your batteries into alternating power (AC) power, like the kind you get in your home, so you can run your electrical appliances wherever you are. There are two types of inverters. Here's a basic guide to help you choose the right one for your needs:

modified sineModified sine wave inverters are very affordable, all purpose inverters. Using a more basic form of technology than pure sine wave inverters, they produce power which is perfectly adequate for powering simple electronics. Use modified sine wave inverters to provide power for your less sensitive appliances like phone chargers, heaters and air conditioners. Modified inverters are best suited for resistive loads which don't have a start up surge.

PureSinePure sine wave inverters use more sophisticated technology to protect even the most sensitive electronics. Pure sine wave inverters produce power which equals – or is better than – the power in your home. Appliances which may not function properly, or which may be permanently damaged, without pure, smooth power will be safe with pure sine inverters. Use these inverters for televisions, laptops, digital microwaves, fridges and other sensitive electronic equipment. Pure Sine inverters can power just about any AC appliance without risk of damage.

How do I prolong my battery life?

The batteries in your caravan, camper trailer or even your boat will continue to slowly discharge while parked in the garage between trips. It’s easy to prolong the life you’re your batteries and save yourself from wasting time and money replacing flat batteries, by following the guide below

Charge your batteries in their downtime with a maintenance charger

While your caravan, camper trailer or boat is sitting idle in the garage, your lead-acid battery will slowly self-discharge at a rate of 3-20% per month. So your battery will become deeply discharged if you don’t charge it regularly. The only way to overcome this is to use a reliable maintenance battery charger, which will keep your battery in good condition while it’s stored away between trips.

Never jump-start your battery

Don’t risk damage to your sensitive electronics by jump-starting your vehicle. Jump-starting batteries creates a huge surge of voltage which can cause irreparable damage to the vehicle’s computer system. It’s much safer to use a charger to bring the battery back to life.

Invest in a smart battery charger

If you invest in a reliable all-round charger you can maintain batteries in a range of your vehicles with one, easy to use battery charger. Bainbridge has a range of smart chargers suitable for almost any application. Most smart chargers are designed to avoid overcharging your batteries ensuring they don’t get permanently damaged. Maintaining you batteries regularly can even extend your battery life, and save you money in the long run.

Test your battery condition

Using products such as a battery monitor or a battery analyser. Gives you the ability to keep an eye on your battery status. The Keepower range of battery chargers, have built in easy-to-use Battery Testers enabling you to test your batteries before you drive.

Invest in a charger with additional functions

There are many different factors that can affect the life of your batteries. It’s best to invest in a  charger which has additional modes such as Desulphation mode, Boost mode or reconditioning mode to ensure you can solve a number of battery related problems.

How should I dispose of batteries?

You should always recycle your batteries to ensure minimal environmental impact. You can dispose your batteries through any of the locations listed below

Batteries are comprised of hazardous components and toxic chemicals that can leak into our environment if they are not properly disposed of. Bainbridge always recommends recycling your old and used batteries to ensure that our soil, air and water stays clean and undisturbed from battery waste.

Batteries can be recycled at any of the locations below:

  • Your Local Battery World Store
  • The place where you purchased the battery
  • A number of online services such as the Australian Battery Recycling initiative will also provide battery recycling services

How do I choose what kind of socket to use?


The kind of socket you choose depends on your power system. Different socket types have different advantages. See below for an overview of the different sockets you can use.

Ciga Socket

The ciga socket is your standard automotive connector. Originally used to house cigarette lighters in cars you will find a ciga socket in just about every vehicle. Because of this, ciga sockets have the broadest range of accessories.Baintech has a range of Ciga Sockets and plugs to suit any system.

Merit Socket inside

Merit Socket

Merit sockets are high quality heavy duty connections that are ideal for high current draw accessories. Merit Socket are smaller than both Ciga and Engel sockets and are becoming the new standard in automotive power connectors.Baintech has a range of Merit Sockets and plugs to suit any system.

Engel Socket inside

Engel Socket

Engel Sockets are designed with screw in connection ensuring your gear won't get disconnected even on the bumpiest road. Suitable for devices that need reliable connections such as the Engel fridge. Baintech has a range of Engel Sockets and plugs to suit any system.

BAINTECH Universal USB Socket Flush Mount

USB Socket

USB stands for Universal Serial Bus and is a type of socket originally designed for fast transfer of information via computers as well as supplying power to peripheral devices. Current USB sockets are also used for smartphones, PDAs, Video Game consoles, and other portable devices. More modern, iPads, tablets, iPhones and Smart phones require a higher amperage USB socket to enable them to charge, this is because the higher functionality and memory capacity of thes devices require more power. Baintech's Universal USB Socket is capable of charging modern devices such as iPads. 

What is an IP rating?

The IP rating on an electrical product is a measure of how much water and dust ingress the product is protected against.

IP stands for Ingress Protection. The first number in the IP rating represents the level of dust protection, and the second number represents the level of water protection. Combined these tell you how well protected your product is. From  IP00 with absolutely no protection, to IP68 which provides maximum water and dust protection. For a detailed look at the IP system, check out the table below.

Protection against entry of objects larger than 12 square mm


Protection against drops of water falling vertically when the luminaire is tilted up to 15 degrees from its normal position


Protection against entry of objects larger than 2.5 square mm


Protection from entry of water spray from angle of up to 60 degrees from vertical


Protection against entry of objects larger than 1.0 square mm


Protection from entry of water splashes or spray from any direction


Protection against entry of dust in sufficient quantity to prevent satisfactory operation


Protection from a low pressure jet of water in any direction


Complete protection against entry of dust


Protection against heavy seas or a strong jet of water in any direction



Protection against immersion up to 1 metre



Protection against submersion over 1 metre

 The IP rating of a product is an important consideration when choosing a battery charger or inverter. For example if your installation is on a boat or other marine application, its important to use products which have an IP68 rating to ensure safety and longevity of your power system.
