SHIDO Lithium Batteries are based on LiFePO4 (Lithium Iron Phosphate) technology. The charging- and discharging capability comes through the chemical reaction of the positive plates (LiFePO4) with the negative plates (Graphite).

There are 2 main reasons why SHIDO Lithium batteries are made with this technology:

• The OCV (Open Circuit Voltage) of these batteries is more stable than any other Lithium-Ion battery

• OCV of one LiFePo4 cell is 3,2 Volt. SHIDO puts 4 cells in their Lithium batteries, so total OCV is 12,8Volt. Standard Lead-Acid Batteries have 6 cells of 2,1 Volt. So, they have 12,6 Volt in total. This means that the LiFePo4 technology approaches as much as possible the Lead-Acid OCV - which is positive for the total electrical circuit of the motorcycle.

For the specialized chemists; here’s the chemical reaction:

LiFePO4 + 6C = Li(1-X)FePO4 + C6LiX

• Superb Cranking Capacity: up to 50% more than Lead-Acid batteries.

• Weight: between 1/3 and 1/5th of Lead-Acid batteries.

• No Sulfating: longer service life.

• Lower Self Discharge: longer shelf life in the warehouse before use.

• Excellent Cycle Life: more than 2.000 cycles (Lead – Acid batteries: +/- 300).

• Drop-in replacement: 1 to 1 replacement dimensions for OEM battery.

• Less Fuel Consumption: thanks to higher OCV the engine works more efficient.

• Super-fast Recharge: very high recharging rate through high current.

• No explosion risk: no gasses are produced during charge or discharge.

• No maintenance: no acid fill, no leak risk, installation in any direction.

• Stable Discharge Voltage: better engine performance, easy engine start.

• Ecological advantage: no pollution, no lead, no acid, safe & normal disposal.

Compared to Digital lithium battery (such as cellphone battery) and lithium power supply battery (such as E-bike battery), SHIDO LION lithium engine start battery has a difference in material, voltage, energy density, discharge rate, safety, cycle life.

See the detail table.

Yes. Thanks to the lower self-discharge rate, the battery voltage will drop slower. This has advantages for the shops: the battery has a longer shelf life before it is installed and used in a motorcycle. And once installed, it will last longer without charging or use than a classic lead-acid battery.

SHIDO lithium battery is made of extremely high energy density lithium iron phosphate material, and it is designed by SHIDO LION patent technology. The watt-density is 5 times higher than existing lead-acid battery, and it can realize the high-rate discharge capacity. So even though the capacity is lower than traditional battery, it can be used normally, and perform better than traditional batteries.

Moreover, lead-acid batteries need the higher capacity to produce the necessary CCA values to start the engines. SHIDO LION batteries produce this CCA without these higher capacities.

On every SHIDO battery you can find the specifications, which includes the voltage in Volts (V) and the total electrical energy in Watt Hour (Wh). This can be found on the front label of every SHIDO battery.

Inside every SHIDO battery there are 4 cells. The BMS management makes sure that all 4 cells are charged and discharged in perfect balance. Like this the power that comes out of the battery is much more stable which helps the overall performance of the battery in producing its power.

On the other side, the management system also takes care of the balanced charge of the 4 battery cells.

All together the result is a longer lifetime of the SHIDO batteries compared to other lithium batteries.

• Higher price than lead-acid batteries.

• Temporary loss of cranking power in very cold conditions (lower than -10 degrees Celsius).

Not relevant. SHIDO Lithium batteries are totally different from any other kind of batteries. The only thing they have in common is the exact dimensions and the polarity (placement of Plus and Minus Terminals).

SHIDO Lithium batteries are made to the exact same dimensions and polarities as the standard OE battery dimensions. So, they can be replaced 1 on 1 without any modification. There is a cross reference list available that shows the SHIDO alternative battery for the most common traditional batteries.

But for some different types of SHIDO batteries we use the same container.

For this reason, we will equip high density stick foam sheets or plastic spacers in the box. You can Install the spacer at the bottom of the battery to adjust the battery’s height or stick on the sides or bottom to fit original battery size. This can be done in just a few minutes. This ensures SHIDO battery maintain same size as original battery. Check the details in SHIDO installation guide.

Every SHIDO Battery has a Battery Led Indicator. The 3 LED’s give the charge state of the battery:

• FULL 3 LED Battery fully charged and ready to use.

• MED 2 LED Battery able to start engine. Burt needs to be charged.

• LOW 1 LED Battery needs to be charged BEFORE starting the engine.

These Waterproof types are specially designed for Jet Ski applications. The sealing between cover and container is waterproof so there is absolutely no risk of water leaking into the battery.

• Regular charging. If not in use.

• Disconnect if not in use.

• Store in a dry and fresh place.

We measure the battery open circuit voltage with a multi meter, then we can preliminarily judge the remaining capacity of the battery. Remove the battery and measure the battery open circuit voltage by multi meter. Then check corresponding remaining voltage by using this sheet.

You can find a how to here.

That depends on many factors. Under the worst conditions, standard lead acid batteries may last only a few weeks and under the best, about five years. In average lead-acid batteries will last 1 to 2 years. Under the same average usage conditions, we expect SHIDO LION to last roughly double, or 2 to 4 years.

All depends on the battery care. Regular use, regular extra charge when not in use will be determinative in the final battery life.

Yes, because there are no liquids in the SHIDO batteries. Any direction installation is permitted, including upside down.

In general, the resistance of SHIDO batteries increase at lower temperatures but they will do their job until -10 degrees Celsius.

But thanks to the special techniques and the intelligent battery management system built into the SHIDO batteries, they perform much better than other Lithium batteries in cold conditions, specially our SHIDO HPs.

There is also a simple trick you can use: if the battery performs poor under extreme cold conditions, use your headlight during 10 – 15 seconds before starting the engine. This will warm up the battery and afterwards she will perform better.

On the other hand, SHIDO batteries can be used in hot environments. The battery works perfectly well up until 60° Celsius environmental temperature. At these temperatures the battery can still supply full power. This is an advantage over standard lead-acid batteries which lose performance in hot environments.

AFAM group does not handle any warranty issues directly with end-customers, but warranties are handled through point of purchase/importers. Please contact your point of purchase.

Compared to lead-acid battery (6 months), the SHIDO battery can be stored for more than a year.

The voltage of lead-acid battery is 12V, the voltage will reduce as the capacity falls as the battery is operating. This leads to action efficiency weakness of spark plugs. But the voltage of SHIDO battery is 13V, and stable. The 1V voltage difference ensures the spark plugs always deliver optimal performance. It can improve the efficiency of spark plugs, producing bigger sparks, so the combustion of gasoline will be more efficient, kinetic energy increases the engine torque, which can improve vehicle running kinetic energy, ultimately improving fuel-efficiency.

That depends on your local and national regulations. SHIDO batteries meet the European RoHS standards for environmental health and contain no lead. Check with your local authority to see if LiFePO4 batteries are allowed.

SHIDO batteries could be charged with most intelligent lead-acid battery chargers. However, there is ONE VERY IMPORTANT RESTRICTION:

Every intelligent lead-acid charger has a desulfation or reconditioning mode. And these modes work different depending on the charger brand or type. Some chargers use a high current pulse to desulfate the lead-acid batteries. This is safe for SHIDO Lithium batteries. Others use a high Voltage mode to desulfate lead-acid batteries. And this is dangerous for EVERY lithium battery. This high voltage can damage the internal cells of Lithium batteries. As a rule: check if your charger never goes above 15 Volt, and it can be used for Lithium batteries. Chargers that use a high voltage characteristic, must also check the internal resistance of the battery. Some intelligent chargers will recognize that the internal resistance is low in SHIDO batteries. That is why they judge that the battery is not sulfated and they will not switch to the high voltage mode. But anyway, you must be very careful with this kind of chargers. Another typical fact on SHIDO batteries is that they don't like “Trickle Charging”. Trickle charging is the stage where the battery cells lie under constant light over – voltage to compensate the natural self – discharge. We recommand to use the SHIDO dual chargers .

In the manual you can find the Charge Current values for each type of SHIDO battery. We indicate 2 different values: one is Standard (STD), the other one is the Maximum charge current.

It is always better to charge your SHIDO battery with the STD charge value. It will take longer, but it is better for the service life of the battery.

However SHIDO batteries can be charged with high currents. In this case it will take much less time to charge your battery. This is the Maximum charge current that is indicated in the manual. We advise to use this MAX charge current only when necessary.

All batteries lose some capacity through self discharge. A top up charge is recommended for best battery health, prolonged service life and it will also give your battery a higher energy density. Even if the indicator shows 3 LED’s, a short top-up charge is advised. Your SHIDO battery is a piece of high technology in your motorcycle, so it should be handled with care from the very beginning.

The cranking power of a battery is indicated in Ampere. This is the current that a battery can supply to the start engine to start the motorcycle engine. The higher the current, the higher the rpm of the start engine will be - and the easier the engine will start.

SHIDO batteries have a CA (Cranking Ampere) that is up to 50% higher than comparable lead-acid batteries. This is very important for all motorcycles, but even more for big twins.

Just look at the name of the two different kinds of batteries:

LITHIUM vs LEAD ACID

The basically elements in SHIDO batteries are Lithium and Carbon.

In lead-acid it is Lead. Apart from the very new technology of SHIDO batteries, also the specific gravity of both base elements in the two different battery types make a world of difference.

Thanks to the lower internal resistance of Copper (CU), the conductivity of current in Copper Terminals is 10 x higher than in Lead (Pb) terminals. All the energy that your SHIDO battery must conduct passes through the terminals. One of the biggest advantages of SHIDO batteries is the ability to discharge (ex: during cranking) and to charge very fast. So, the Copper terminals give the SHIDO batteries an enhanced electrical and mechanical performance.
