Part # 299112
INTACT 12V 21AH Gel Battery

Intact Bike Power Battery GEL 51913 for BMW. Our absolute top product for motorcycle batteries is the intAct Bike-Power Gel series. This series was developed especially for modern motorcycles with various electrical consumers and ABS. By combining the fleece separators and the fixed electrolyte in gel, up to 30% more power is achieved compared to conventional motorcycle batteries. The batteries also impress with very low self-discharge and very high vibration resistance.

Width x depth x height = 183 x 78 x 171 mm
Cold start current: 300 A (DIN)

The main advantages:

Please Note: Information about treatment and maintenance of your battery

A battery is only an energy storage device and any energy removed must be returned to it immediately 100% by the generator of the vehicle or externally by a charger, if the energy balance is rather negative due to short-term use or due to generally few use times with longer stance phases.

To ensure a long battery life, you should observe the following:

• Use of the battery only for its intended purpose (starter batteries for starting and operating a vehicle with internal combustion engine).
• The surface of the battery must be kept clean and dry, no oils or liquids must be deposited on it to avoid the formation of leakage currents which can cause considerable self-discharge.
• If possible, check battery level at least every 6 months and top up with purified water if necessary (do not top up with accumulator acid).
• In case of high water loss, please have the function of the charge controller checked by a specialist. With an optimal installation location and normal requirements, your battery will consume little to no water, but these factors are very different depending on use.

If your vehicle tends to have a negative energy balance due to use (short distances - longer stance phases - high comfort equipment - start-stop operation), the battery charge state should be checked at necessary intervals (2 - 3 months). Check the charge (open-circuit voltage) of your battery every 2 months at the latest and recharge it if necessary. Due to the continuous chemical process, every battery is subject to self-discharge, which inevitably leads to the deepest discharge of your battery if this is not compensated by charging. If this is still connected to the vehicle, the discharge may be even faster, as the vehicle may also consume a standby current. It is best to disconnect the battery.

In order to always have sufficient starting safety and not to cause any damage to the battery, it should always be charged at least 75%. This can be determined with the open-circuit voltage or with an acid lifter.

Normal voltage:

• 12.51 V - 12.57 V = 75 % charged
• 12.69 V - 12.75 V = 100 % charged

Acid density:

• 1.25 kg/l = 75 % charged
• 1.28 kg/l = 100 % charged
