2. Sikkerhedsoplysninger
Always observe the following safety precautions when handling, installing, or maintaining sealed lead acid batteries:
- Øjenbeskyttelse: Brug altid passende øjenbeskyttelse (sikkerhedsbriller eller beskyttelsesbriller), når du arbejder med batterier.
- Hudbeskyttelse: Wear gloves to protect hands from potential acid exposure, although these are sealed batteries, caution is advised.
- Ventilation: Ensure adequate ventilation when charging batteries to dissipate any gases that may be produced.
- Kortslutninger: Avoid short-circuiting battery terminals. This can cause severe burns, fire, or explosion. Do not place tools or metal objects on top of the battery.
- Opladning: Use only chargers specifically designed for sealed lead acid batteries with appropriate voltage and current ratings. Overcharging can damage the battery and pose a safety risk.
- Bortskaffelse: Do not dispose of batteries in fire. Batteries contain lead and sulfuric acid and must be recycled according to local regulations.
- Skade: Do not use batteries that show signs of damage, swelling, or leakage.
3. Opsætning og installation
Proper setup ensures optimal performance and longevity of your Enersys NP7-12 batteries.
- Inspektion: Upon unboxing, inspect the batteries for any physical damage.
- Orientering: These batteries can be operated in any orientation except continuously inverted. Ensure they are securely placed to prevent movement.
- Forbindelse: Connect the batteries to your device or charging system. Ensure correct polarity: positive (+) to positive, negative (-) to negative. Loose connections can cause overheating and poor performance.
- Indledende opkrævning: While batteries typically arrive with a partial charge, a full initial charge is recommended before first use, especially if the batteries have been stored for an extended period.

4. Betjeningsvejledning
The Enersys NP7-12 batteries are designed for reliable performance. Follow these guidelines for optimal operation:
- Opladning Voltage:
- Float Charge: 13.5 - 13.8V at 25°C (77°F)
- Cyclic Charge: 14.4 - 15.0V at 25°C (77°F)
- Temperatur: Operate batteries within their specified temperature range. Extreme temperatures can affect performance and lifespan.
- Udledning: Avoid deep discharges. Repeated deep discharges can significantly reduce battery lifespan. Recharge batteries promptly after use.
- Opbevaring: If storing batteries for an extended period, ensure they are fully charged and stored in a cool, dry place. Periodically recharge them every 3-6 months to prevent self-discharge.
5. Vedligeholdelse
Enersys NP7-12 batteries are maintenance-free in terms of water addition. However, regular checks can help ensure optimal performance:
- Terminalrengøring: Periodically inspect battery terminals for corrosion. Clean with a wire brush and a mixture of baking soda and water if necessary. Ensure terminals are dry before reconnecting.
- Tilslutningskontrol: Verify that all connections are tight and secure. Loose connections can lead to resistance, heat buildup, and power loss.
- Fysisk inspektion: Regularly check the battery casing for any signs of damage, cracks, or swelling.
- Charging System Check: Ensure your charging system is functioning correctly and providing the appropriate voltage og nuværende.
