Choosing car and motorbike accessories: a practical guide to batteries, maintenance and upgrades

A flat battery, poorly visible dashboard information or a missing navigation solution can make a journey unnecessarily complicated. When choosing car and motorbike accessories, it is therefore not just about the price or an impressive amp rating. Above all, check that the product suits your vehicle, how you intend to use it and your technical requirements.

Three common purchasing pitfalls

1. Confusing peak values with everyday use

With a car jump starter, the peak current is often displayed prominently on the packaging. This figure does not automatically indicate how long, or under what conditions, the device can support a vehicle. Also check the starting current, vehicle voltage and stated suitability for petrol or diesel engines.

A 12V jump starter is intended for vehicles with a 12V system. That does not mean every model is suitable for every engine size, van or boat. Always check the product specifications before buying.

2. Capacity on paper is not everything

Battery capacities for emergency power banks and jump starters are usually stated in mAh. The stated capacity may differ from the usable or nominal capacity. For example, the Porbi S306 lists 12.800 mAh, with a nominal capacity of 7.200 mAh. The Porbi S901 lists 14.000 mAh, with a nominal capacity of 10.000 mAh.

For practical use, charging time, USB output, dimensions and storage conditions are also important. A small device left unused in a hot car requires extra care, too. According to the product information, these jump starters should not be stored at high temperatures, in damp conditions or in direct sunlight.

3. Universal accessories are not always plug-and-play

A motorbike CarPlay screen, motorbike camera or digital motorbike dashboard may seem appealing because of broad compatibility claims. However, plugs, supply voltage, mounting dimensions and communication protocols can vary between motorbikes.

For a universal dashboard, the product information explicitly states that functionality depends on the vehicle controller and wiring. Before buying, check:

  • the available space on the handlebars or dashboard;
  • the supply voltage and connections;
  • the mounting diameter;
  • compatibility with your motorbike, scooter or electric motorbike;
  • whether installation by a qualified professional is required.

Important parameters for car and motorbike accessories

Batteries and electrical systems

For car maintenance and motorbike maintenance, three things are essential:

  1. Voltage: a 12V battery charger is suitable for a 12V battery, but you should also check the battery type.
  2. Capacity range: a charger must match the capacity in Ah. According to the product information, the EAFC 12V 6A charger is specified for batteries from 4 to 100 Ah. The 12A model is specified for 2 to 150 Ah.
  3. Battery technology: AGM, GEL, EFB, wet lead-acid and calcium batteries may require different charging modes.

A battery charger with protection against reverse polarity, short circuits and overheating provides useful safety features. This does not replace carefully following the instructions. When charging indoors, good ventilation is important, and you should follow the correct connection and disconnection sequence.

A battery tester for checking before a breakdown

A battery tester can help you check voltage, resistance, charge status and starting performance. According to the product description, the VDIAGTOOL BT500 is intended for 6V, 12V and 24V batteries and supports CCA, BCI, DIN and SAE standards, among others. The same information states that the device is not intended for lithium batteries, deep-cycle batteries or certain golf cart batteries.

Bear in mind that a measurement depends on the battery type selected and the CCA value entered. Use the meter according to the instructions and treat the result as technical information, not as a guarantee of how much service life a battery has left.

Tools and fastening

An electric ratchet wrench is particularly useful if you regularly loosen or tighten bolts in hard-to-reach places. Check the maximum torque, drive size and weight. According to the product information, the EAFC ratchet wrench has a 3/8-inch drive, a stated maximum torque of 45 Nm and a weight of approximately 0,78 kg.

Higher torque is not always desirable. For small fasteners, it may still be necessary to tighten them by hand to the specified torque. Use suitable sockets and check that the wrench is appropriate for the job.

Other accessories worth considering

For navigation and connectivity, you could compare a motorbike CarPlay screen, such as a 5-inch or 7-inch Carpuride model. Check its water resistance, mounting, Bluetooth, intercom and how the screen is powered.

For recording footage, a motorbike camera such as the SJCAM C200 Pro is designed for compact mounting and action footage. According to the product information, this camera supports features including 4K recording, electronic image stabilisation and use to a specified water depth. Read the safety instructions regarding the battery, seals and charging carefully.

A digital motorbike dashboard can display speed, battery level and gear, but requires extra attention to wiring and vehicle compatibility. If you enjoy doing your own maintenance, you could also use an electric ratchet wrench for work on a motorbike, scooter or car. A decorative motorbike accessory, such as a wind-powered ornament, serves a different purpose and should not be assessed on technical vehicle functions.

Frequently asked questions about car and motorbike accessories

Which car and motorbike accessories are useful in the event of a breakdown?

A car jump starter, battery tester, torch and suitable cables provide a practical foundation. An emergency power bank with a USB output can also charge a phone or navigation device. Check the jump starter’s battery regularly and store the device according to the product instructions.

How long does a jump starter or battery charger last?

Its service life depends on storage temperature, charging frequency, use and maintenance. A lithium jump starter should not be stored empty for long periods. Recharge it according to the manual and, before a long journey, check that the battery indicator still shows sufficient capacity.

Can I use a 12V battery charger for every motorbike battery?

No. Check the voltage, Ah capacity and battery technology. A 12V battery charger suitable for lead-acid, AGM or GEL is not automatically suitable for lithium. Only use a charging mode that matches your battery and follow the connection sequence in the manual.
