Teknik Penjagaan Bateri Kereta - Battery Maintenances

Cara Menjaga Bateri Kereta

1. Periksa bateri jika terdapat tanda-tanda kerosakan seperti retak, bocor, karat, penutupnya hilang, kepala longgar dan sebagainya. Jika terdapat kesan debu putih dibahagian terminal, dan air baterinya cepat kering, kemungkinan kuasa yang disalurkan kepada bateri itu terlalu tinggi. Bila keadaan ini berlaku, perlulah ia diperbaiki dengan secepat mungkin, untuk mengelakkan kerosakan teruk pada bateri. Kesan-kesan bocor dapat diketahui jika terdapat disekitar dan bawah bateri berdebu garam putih kehijauan.

2. Periksa paras air bateri sekurang-kurangnya seminggu sekali. Perkara ini pada kebiasaannya dilakukan oleh pekerja stesen pam minyak. Jika airnya kurang, tambah dengan air bateri (distilled water). Air sejuk yang bersih boleh juga digunakan.Walau bagaimanapun jangan bubuh airnya berlebihan dari paras yang ditentukan sebab ini akan menyebabkan air bateri itu melimpah dan mungkin menyebabkan kerosakan selanjutnya kepada bahagian-bahagian besi. Untuk panduan anda, isi air itu sehingga bahagian hitam didalam bateri sahaja yang ditenggelami air.

3. Sekiranya terdapat kesan kesan debu garam putih dikedua-dua terminal bateri, bersihkan dengan menggunakan bancuhan natrium karbonat (serbuk penaik - baking powder) dengan sukatan satu sudu teh serbuk dalam satu cawan air. Bancuhan ini dibubuh atas terminal bateri dan ia akan berbuih. Buih-buih ini akan berhenti bila ia sudah bersih. Seterusnya bilas dengan air sejuk biasa. Kuatkan ikatan kepala bateri jika perlu dengan rapi.

4. Kuatkan kuasa bateri menggunakan battery charger jika perlu. Elakkan diri dari menggunakan ubat-ubat bateri yang terdapat dikedai. Bahan-bahan ini biasanya diakui boleh menguatkan bateri, tapi sebenarnya perbuatan ini sia-sia sahaja.Air bateri yang dijual dikedai adalah dari jenis air sulingan (distilled water), tapi bila diisi dalam bateri ia akan bercampur dengan air bateri dan seterusnya menjadi cecair asid sulfurik. Jadi elakkan asid ini dari terkena pakaian atau kulit anda. Jangan sesekali tambahkan asid sulfurik kedalam bateri.

Tyre care and maintenance - Basic tips

Step 1 - Keep your wheels balanced
Balancing your wheels is crucial to making sure they spin correctly. Have your local tyre centre balance the wheels by attaching small weights to the wheel rim. These weights will equalize any distortion in the construction of your wheels or their rims. If you notice a vibration through the steering wheel, you may want to rebalance your wheels. At least bring your car to the tyre centre to see if that's the way to go.

Good tyre care
With all the time your loved ones spend in a car, you need your tyres to be in tip-top shape. And proper tyre care is your ticket to ride - safely. In these three easy steps, The Expert tells you how to keep your tyre care simple and effective.

Step 2 - Make sure your wheels are properly aligned

Alignment keeps your tyres in even contact with the road surface. It's crucial to your car's tyre life and relatively cheap to have carried out. Whenever the tread is wearing unevenly or you're driving unevenly - no matter how straight you are going - it may be a sign to have the alignment checked out. Check for signs of uneven tyre wear and if you bump into a kerb have the alignment checked.

Step 3 - Take the time to rotate those tyres

Most tyre companies will tell you to rotate all four tyres approximately every 5000 miles. For the less fastidious, the Expert recommends that you do so at least every 10,000 miles, especially for front-wheel drive vehicles. Also, keep in mind that there are different types of tyre rotation possible. Your owner's manual should recommend the preferred method for your vehicle, which you can then share with your mechanic. In addition to the above, the simplest way to improve your car's steering, handling and braking is to ensure that your tyres are inflated to the correct pressures. Make sure that you increase tyre pressure, as recommended by your manufacturer, when you load up your vehicle.

Energy and Fuel - Saving Tips (Part 2)

5. Avoid drag. Where possible keep all windows closed and ensure that the doors, bonnet (hood), and boot (trunk) are securely fastened.

6. To drive economically you need to maintain a sufficient distance between your car and the vehicle ahead. This way there is less need to react suddenly, and you can brake and accelerate more smoothly.

7. On bends, reduce speed in time and accelerate smoothly when you are halfway through a bend. Late, heavy braking before a bend followed by rapid acceleration leads to excessive fuel consumption.

8. If you watch the roads ahead and anticipate any likely problems, your driving style will become smoother and better controlled.

9. Tires in good condition and at the right pressure improve both safety and fuel consumption. Be sure to check your tires regularly.

10.Ensure your car is properly and regularly maintained. Poor engine lubrication, wheel alignment and poorly adjusted brakes can increase fuel consumption.
