| Condition requiring initial charge | Charging method |
| At low temperatures (lower than 0°C) | 0.9 A x 2-3 hours |
| Battery has been stored in high temperature and humidity. | 0.9 A x 15-20 hours |
| Seal has been removed, or broken - peeling, tear or hole. (If you did not hear the air-sucking sound "Shoosh!" as you removed the seal). | |
| Battery as old as 2 years or more after manufacture. Battery manufacturing date is printed on battery top. |
Example:
- 12 Day
- 10 Month
- 93 Year
- T1 Mfg. location
Note 1 : Terminal voltage - To measure battery terminal voltage, use a digital voltmeter.
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 sealing plug 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 the Electrical System chapter).
- When a fast charge is inevitably required, do it following precisely the maximum charge current and time conditions indicated on the battery.
Caution!
- 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 sealing plug during refresh charge.
- If by chance an excessive amount of gas is generated due to overcharging, the safety valve operates to keep the battery safe.
- 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 lead removed. Give a refresh charge every 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).
Warning!
- Keep the battery away from sparks and open flames during charging, since the battery gives off an explosive gas mixture of hydrogen and oxygen. 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.
- No fire should be drawn near the battery, or no terminals should have the tightening loosened.
- 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. Get medical attention if severe.
Interchange
A maintenance free battery can fully display its performance only when combined with a proper vehicle electric system Therefore, replace a maintenance free battery only on a motorcycle which was originally equipped with a maintenance free battery.
Be careful, if a maintenance free battery is installed on a motorcycle which had an ordinary battery as original equipment, the maintenance free battery's life will be shortened.
