Kawasaki Z1000SX - Service manual > Precautions

1) No need of topping-up.

No topping-up is necessary in this battery until it ends its life under normal use. Forcibly prying off the seal cap to add water is very dangerous. Never do that.

2) Refreshing charge.

If an engine will not start, a horn sounds weak, or lamps are dim, it indicates the battery has been discharged. Give refresh charge for 5 to 10 hours with charge current shown in the specification (see Refreshing Charge).

When a fast charge is inevitably required, do it following precisely the maximum charge current and time conditions indicated on the battery.

NOTICE This battery is designed to sustain no unusual deterioration if refresh-charged according to the method specified above. However, the battery's performance may be reduced noticeably if charged under conditions other than given above. Never remove the seal cap during refresh charge. If by chance an excessive amount of gas is generated due to overcharging, the relief valve releases the gas to keep the battery normal.

3) When you do not use the motorcycle for months.

Give a refresh charge before you store the motorcycle and store it with the negative cable removed.

Give a refresh charge once a month during storage.

4) Battery life.

If the battery will not start the engine even after several refresh charges, the battery has exceeded its useful life. Replace it (Provided, however, the vehicle's starting system has no problem).

DANGER Batteries produce an explosive gas mixture of hydrogen and oxygen that can cause serious injury and burns if ignited. Keep the battery away from sparks and open flames during charging. When using a battery charger, connect the battery to the charger before turning on the charger. This procedure prevents sparks at the battery terminals which could ignite any battery gases. The electrolyte contains sulfuric acid. Be careful not to have it touch your skin or eyes. If touched, wash it off with liberal amount of water and seek medial attention for more severe burns.

Interchange

A sealed battery can fully display its performance only when combined with a proper vehicle electric system. Therefore, replace a sealed battery only on a motorcycle which was originally equipped with a sealed battery.

Be careful, if a sealed battery is installed on a motorcycle which had an ordinary battery as original equipment, the sealed battery's life will be shortened.

Charging Condition Inspection

• Battery charging condition can be checked by measuring battery terminal voltage with a digital voltmeter [A].

• Remove:
  Seats (see Seats section in the Frame chapter)
• Disconnect the battery terminals.

NOTICE Be sure to disconnect the negative (-) cable first.

• Measure the battery terminal voltage.

NOTE

• Measure with a digital voltmeter which can be read one decimal place voltage.

If the reading is 12.8 V or more, no refresh charge is required, however, if the read is below the specified, refresh charge is required.

Battery Terminal Voltage
 Standard: 12.8 V or more

Terminal Voltage (V) [A]
Battery Charge Rate (%) [B]
Good [C]
Refresh charge is required [D]

Refreshing Charge

• Remove the battery [A] (see Battery Removal).
• Do refresh charge by following method according to the battery terminal voltage.

WARNING This battery is sealed type. Never remove sealing cap [B] even at charging. Never add water. Charge with current and time as stated below.

Terminal Voltage: 11.5 - less than 12.8 V
 Standard
 Charge: 0.9 A × 5 - 10 h (see following chart)
 Quick Charge: 4 A × 1 h

NOTICE If possible, do not quick charge. If quick charge is done unavoidably, do standard charge later on.

Terminal Voltage: less than 11.5 V
 Charging Method: 0.9 A × 20 h

NOTE

• Increase the charging voltage to a maximum voltage of 25 V if the battery will not accept current initially. Charge for no more than 5minutes at the increased voltage then check if the battery is drawing current. If the battery will accept current decrease the voltage and charge by the standard charging method described on the battery case. If the battery will not accept current after 5 minutes, replace the battery.

Current starts to flow [D]

• Determine the battery condition after refresh charge.
  • Determine the condition of the battery left for 30 minutes after completion of the charge by measuring the terminal voltage according to the table below.
