Frequently Asked Questions

X Series

1) X9 / F1 - 18 or 36 Hole Battery?

We are not able to guarantee any battery for 36 holes for the following reasons.

• 18 holes of golf is not a finite measurement. There can be a difference of several miles from a short to a long course (taking the distance between green and tee in to account too).
• Terrain, ground condition, bag weight, and a number of other factors can make a big difference. Imagine running along a flat concrete road as opposed to up a steep sand dune & you'll get the idea.
• The quality of the golf also affects how far you walk. A golfer shooting 65 will walk a lot less than a golfer shooting 110 and zig-zagging up the fairways! This scenario would also see the steering being used more, which also consumes more power.

Many customers have completed 36 holes with their trolleys on a single charge, however if you play 36 on a regular basis we recommend that you purchase an additional battery pack.

2) Are X9 batteries compatible with lead acid chargers?

X9 batteries must only be charged using the charging equipment supplied with the battery. It is not possible to charge the battery using any other charging equipment.

3) Are X9 batteries dangerous?

No is the simple answer! Unfortunately certain other types of Lithium battery can be dangerous if not treated in the correct manner. The X9 battery is made from LiFePO4 (Lithium ion Phosphate) which is widely recognised as the safest type of lithium battery. This makes it the material of choice for electric vehicle manufacturers.

4) How long will an X9 battery last?

The lifetime of a battery is determined by a number of factors including regularity of play, weight of golf bag, course type, trolley age and trolley type. With this in mind it is not possible to predict how long a battery will last. Despite this, we are confident that an X7 Lithium battery will last five times longer than a lead-acid equivalent.

5) How should an X9 battery be stored if not used for considerable periods of time?

For storage in excess of four months, it is recommended to fully charge the battery before reducing the level of charge to around 60% (ideally by using it for 40% of its capacity). It should then be fully charged prior to its next use.

6) Is it possible to use an X9 battery and still use a lead-acid battery?

Yes. The X9 battery is designed to work just like a lead acid battery with no modification required.

7) Should a X9 battery be recharged if not been used for a full round?

X9 batteries do not suffer from a “memory effect” seen in certain other high technology batteries. This means that it will not cause any damage to the battery. The only effect will be a quicker charge!

8) What is the best way to maximise the life of an X9 battery?

Thanks to the advanced battery management system, the X9 battery is protected against overcharging and excessive discharge during use. Despite this there is still a danger of damage to the battery if left un-charged after use. The best way to prolong the life of your battery is to charge it as soon as possible after each round.

9) What is the safest way to dispose of an X9 battery?

At Stewart Golf we are dedicated to protecting the environment and strongly recommend disposing of our batteries in a safe and environmentally friendly way. X9 batteries can be taken to a registered recycling point or alternatively returned to Stewart Golf to allow us to recycle them.

10) What maintenance is recommended for X9 batteries?

In addition to regular charging, it is recommended to regularly check the battery connections and keep the battery clean with a damp cloth.

11) What battery can I use as a replacement on my X1, X3, X5, X7 or X9?

1. Lead Acid

This is the equivalent battery that was supplied with the X1, X3 and X5.
Providing your original charger is in good working order, you will be able to use this with a replacement lead-acid battery.

2. Lithium Phosphate (LiFePO4)

This is the battery that is supplied as standard with the X7 Lithium and X9 models and is the option that we recommend. It has several significant benefits over the lead-acid battery, such as:

Weight reduction (3kg instead of 12kg)
Smaller size
Longer overall life
More reliable charging
Constant power delivery (so the trolley won't slow towards the end of a round)

This is supplied as a set with battery and charger - your old lead-acid charger will not charge the new lithium battery.
