Batteries & Accessories

Is your starter cranking slowly, or does the battery need to stay firmly in place in a build that sees harder driving? In this category we bring together batteries, battery hold-downs and accessories for charging and jump starting – for you who want reliable starts and a battery that stays put.

Battery, hold-down and accessories – what do the parts do?

The battery supplies power to the starter and feeds the electrical system when the engine is off. While driving, the charging system takes over. A battery that quickly goes flat can therefore also be caused by a fault in the charging system. A battery hold-down secures the battery so it does not move under vibration and hard manoeuvres, and it can protect terminals and cables. The accessories include, for example, jump starter cables, smart clamps and wall chargers from Antigravity Batteries, each of which is specified for particular XP models.

How to choose a battery

Among the batteries you will find, for example, AGM batteries from BikeMaster, and the category also includes brands such as Yuasa Battery, TwinPower and DS18. Choose based on several factors at once:

• Dimensions and terminal layout, so the battery fits the hold-down and the cables can reach the terminals.
• Capacity relative to the electrical system's consumption, e.g. if you have fitted extra lighting or audio.
• Cranking current, which should suit the engine and the temperatures you drive in.
• Battery type, as AGM and other types can have different charging requirements.

The right choice depends on the specific part number and your vehicle, so compare the data for your current battery with the new one.

Installation and maintenance

The battery must sit firmly without the hold-down squeezing the case, and the terminals must be clean and correctly tightened. For jump starting accessories, check that the cable and clamps match your exact XP model – the designation is in the product name. If the vehicle stands unused for longer periods, a suitable charger can help keep the battery maintained; whether a charger is suitable depends on the battery type. If you also need to renew cables and connectors, you will find them under electrical wiring.

Frequently asked questions

Why should the battery be secured in a hold-down?

A loose battery can move under vibration, braking and cornering. This can stress terminals and cables and, in the worst case, cause a short circuit. A hold-down that matches the battery's dimensions keeps it in place without squeezing the case.

What should I watch out for if I switch to an AGM battery?

AGM batteries can have different charging requirements than conventional batteries. Check that the charging system and any charger suit the battery type, and compare dimensions, terminal layout and cranking current with the battery you are replacing.

Do the Antigravity Batteries accessories fit all models?

No. Jump starter cables, clamps and wall chargers are specified for particular models, e.g. XP-1, XP-3 or XP-10. Check the model designation in the product name, and note the connector type on the wall charger before you order.

Why does a new battery keep going flat?

It can be caused by a charging system that does not charge correctly, current draw while the vehicle is parked, or a battery with too little capacity for the electrical system. Have the charging voltage and parasitic drain measured before you replace the battery again.
