Frequently asked questions

There is sometimes confusion about the definition of different types of Powersports (Motorcycle etc) Batteries and conflicting information about the maintenance of the different types of batteries. We have outlined a number of frequently asked questions and answers below :
Q. My battery is completely sealed, it’s a GEL battery right?
A: In most cases the answer is "no". The huge overwhelming majority of sealed batteries are AGM (absorbed glass matt), this includes Original Equipment batteries supplied by the manufacturer. This is where the acid is absorbed in the glass matt sponge like material between the plates, so there is very little, if any free moving acid in battery. This method of manufacturing allows excellent vibration resistance, high cranking and a very low discharge rate, all attributes that are very important to Powersports applications.

AGM batteries are normally supplied either factory activated, where the acid has been added at the factory before the batteries are shipped out.Or supplied with an acid pack, so that the dealer, battery specialist or user can activate the battery prior to use.

We always supply, where possible, batteries with acid packs and not factory activated products. This is due to the fact that when the acid is added to the battery, it begins to age and deteriorate. When you take into account shipping and stocking time at various points, you may get a battery which is already 1 year old when you buy it "new" battery from a shop.
Q. What is better for my bike ? A Flooded, AGM or GEL Battery?
A. Flooded (WET) batteries have been around for many years providing a good solution to the needs of many applications. However, as time has moved on and sports bikes have greater lean angles, side mounted batteries, higher cranking requirements and greater safety concerns in the event of an accident, AGM batteries have been able to provide a solution to all of the above.

We always recommend a AGM battery where there is one of suitable size available.

GEL batteries do not provide any benefits over Himura AGM batteries for Powersports applications. In fact we have undertaken the deconstruction of many "GEL" labelled motorcycle batteries in the UK and just about all were of AGM construction.
Q. Should I leave my battery constantly connected to a trickle charger when not using it?
A. This depends on the type of trickle charger used, the time the battery will be left unused, and the drain on the battery from the vehicle. There are many chargers which are sold as being able to be left connected indefinitely to the battery, and in many cases they can be. However, as a rule we always advise where possible, remove/disconnect the battery from the vehicle to prevent any drain, then put it on a charge cycle once a month. We believe that this is the best solution.

Where it is difficult to remove/disconnect the battery, and a constant drain such as an alarm is present, it may be necessary to leave a maintenance charger connected. In such cases the best type of chargers are multistage ones that supply a very light pulse charge at the end of the charge cycle, or allows the battery voltage to drop to a predetermined level then charges it up to a point and stops, repeating the cycle. The chargers which provide a constant voltage/amp trickle can quite easily overcharge/dry out the battery leading the battery to premature failure.

Most people are unaware that many bikes are designed without an alarm fitted, these tend to be retro fitted by dealers. As such the alarm drain on the battery is never taken into account with the sizing of the original battery. Since Motorcycle/Powersports batteries are very small in size this drain can cause considerable shortening of a batteries lifespan, meaning a good maintenance charger is a necessity for most.
Q. I left my battery on my bike over the winter, the bike won’t start now. If I charge it up will it be ok?
A: If it has been left on all winter without use and is completely flat, irreversible damage would have been caused to the battery, and if the battery is able to be recharged, the life of the battery would have most certainly have been reduced.

Leaving a battery go flat allows a chemical process called sulphation to happen on the battery plates. Essentially this renders parts of the battery plates unusable therefore reducing its capacity. Some chargers have the ability to reverse a small amount of this sulphation, but any prolonged discharging of a battery will lead to a permanent reduction in capacity and performance of the battery.
Q. I have connected my battery to my charger correctly, but nothing is happening, what’s wrong ?
A. Many chargers have a predetermined minimum voltage before it recognises that a battery is connected. Sometimes this is around 6 to 9 volts, this is so that it recognises if a battery is connected the wrong way round. Also if a battery is discharged to that level, almost certainly irreversible sulphation would have taken place and a new battery will be needed.
Q. What is the best charger for my battery ?
A. Firstly, it must be mentioned that connecting a powersports battery to an automotive/car or fast charger will damage it. Always use a specifically designed maintenance charger for the size of battery.

There are many chargers on the market for Powersports/Motorcycle Batteries. We would always recommend a charger which is multi stage but also has a light pulse function when the normal charge cycle has finished, or one which allows the battery voltage to drop slightly before starting the charger cycle again.

As the market changes and new chargers are released all the time, it is hard to make a specific recommendation, however feel free to email us with specific questions on chargers.
