Avoid using standard lead-acid battery chargers, as they deliver an incorrect voltage and charging profile, which will severely compromise the battery’s performance and lifespan. Refer to the BMPRO website or contact customer support for a list of tested and approved compatible chargers. Using non-approved chargers voids the warranty.
Charging Procedure – Step-by-Step
Follow these steps to safely and effectively charge your BMPRO Battery Plus 35 11 HA: First, ensure the battery is placed on a non-flammable, well-ventilated surface. Connect the compatible charger’s output cable to the battery’s charging port, verifying a secure connection.
Plug the charger into a standard AC power outlet. The charger’s indicator light should illuminate, signifying the charging process has begun. Allow the battery to charge fully, typically indicated by a change in the charger’s light (refer to ‘Charging Indicators’).
Once fully charged, disconnect the charger from the power outlet before disconnecting it from the battery. Do not leave the battery connected to the charger indefinitely, even after reaching full charge. Regular, complete charge cycles are recommended for optimal performance.
Charging Indicators and Troubleshooting
Understanding the charging indicators is crucial for proper battery management. A solid red light typically indicates the battery is actively charging. A flashing red light may signal an error or incompatibility with the charger. A solid green light usually confirms a full charge.
Troubleshooting: If the battery isn’t charging, verify the charger is properly connected to both the battery and a functioning power outlet. Try a different compatible charger. If the indicator light doesn’t illuminate, the battery or charger may be faulty.
For a consistently slow charge, inspect the charging port for debris. If issues persist, consult the warranty information or contact customer support for assistance. Never attempt to disassemble or repair the battery yourself.

Using the Battery with Devices
Connect the BMPRO Battery Plus 35 11 HA to your device using the appropriate cable, ensuring correct polarity for optimal power delivery and safety.
Connecting the Battery to Devices
Before connecting the BMPRO Battery Plus 35 11 HA to any device, carefully review the device’s power requirements. Ensure the battery’s voltage and current output are compatible to prevent damage. Utilize the provided connectors or high-quality, appropriately rated cables. Incorrect connections can lead to malfunction or safety hazards.
Always observe correct polarity – positive to positive and negative to negative. Reversing polarity can cause immediate and irreversible damage to both the battery and the connected device. Securely fasten all connections to prevent accidental disconnections during operation. For devices with specific input jacks, use the corresponding adapter if necessary.
Double-check all connections before powering on the device. If the device fails to power on, immediately disconnect the battery and re-verify the connections and compatibility. Avoid forcing connections; ensure a snug, but not overly tight, fit.
Power Output and Compatibility
The BMPRO Battery Plus 35 11 HA delivers a consistent power output, suitable for a wide range of devices. However, compatibility hinges on matching the battery’s specifications with the device’s power demands. This battery is designed to provide reliable power for equipment requiring stable voltage and sufficient amperage.
Prior to use, confirm your device’s input voltage falls within the battery’s output range. Exceeding the device’s voltage limit can cause damage, while insufficient voltage may result in improper function. Consider the device’s power consumption (watts or amps) and ensure the battery’s capacity can sustain it for the desired duration.
This battery is generally compatible with devices utilizing standard DC power inputs. Always consult the device’s manual for specific power requirements and compatibility guidelines. Improper usage voids the warranty and may pose safety risks.

Maintenance and Care
Regular maintenance ensures longevity and optimal performance of your BMPRO Battery Plus 35 11 HA. Proper care includes cleaning and following storage guidelines.
Cleaning the Battery
Maintaining a clean BMPRO Battery Plus 35 11 HA is crucial for optimal performance and longevity. Before cleaning, always disconnect the battery from any connected devices and ensure it is powered off. Use a soft, dry cloth to wipe down the exterior casing, removing any dust, dirt, or debris.
Avoid using water, solvents, or abrasive cleaners, as these can damage the battery’s internal components or exterior finish. For stubborn dirt, lightly dampen the cloth with a mild, non-abrasive cleaning solution, ensuring it is wrung out thoroughly to prevent moisture from entering the battery.
Pay particular attention to the terminals, ensuring they are free from corrosion. If corrosion is present, carefully clean it with a specialized terminal cleaning brush or a mixture of baking soda and water, followed by a thorough drying. Always inspect the battery for any signs of damage during cleaning, and discontinue use if any cracks or leaks are observed.
Long-Term Storage Procedures
Proper storage is vital to preserve the BMPRO Battery Plus 35 11 HA’s lifespan when not in use for extended periods. Ideally, store the battery in a cool, dry environment, away from direct sunlight and extreme temperatures. The recommended storage temperature range is between 59°F (15°C) and 77°F (25°C).
Before storing, discharge the battery to approximately 50-60% of its capacity. Fully charged or completely discharged batteries degrade faster during long-term storage. Store the battery in a clean, non-conductive container to prevent accidental short circuits.
Periodically check the battery’s charge level (every 3-6 months) and top it up to the 50-60% range if necessary. Avoid storing the battery in humid environments or near flammable materials. Following these procedures will help maintain the battery’s health and ensure it’s ready for use when needed.

Troubleshooting Common Issues
This section details solutions for typical problems with the BMPRO Battery Plus 35 11 HA, like charging failures or reduced runtime, for optimal usability.
Battery Not Charging
If your BMPRO Battery Plus 35 11 HA isn’t charging, first verify the charger is securely connected to both the battery and a functioning power outlet. Confirm the charger is compatible – using an incorrect charger can prevent charging or even damage the battery.
Next, inspect the charging port on the battery for any debris or damage. Clean it gently with a dry cloth if necessary. A faulty charging cable is also a common culprit; try a different cable known to be working.
If the issue persists, check the battery’s charging indicator (if equipped). If no indicator lights up, the battery might be deeply discharged and require a specialized charger or professional attention. Ensure the battery is within its operating temperature range, as extreme temperatures can inhibit charging. Finally, consider if the battery has reached the end of its lifespan.
Reduced Battery Life
Experiencing shorter runtimes with your BMPRO Battery Plus 35 11 HA is common over time, but a significant decrease warrants investigation. First, assess your device’s power consumption; some devices draw considerably more power than others. Ensure you’re not exceeding the battery’s maximum discharge rate.
Extreme temperatures – both hot and cold – can negatively impact battery performance. Avoid exposing the battery to these conditions. Improper storage also contributes to capacity loss; follow the long-term storage guidelines in this manual.
Frequent shallow discharges are preferable to deep discharges, which stress the battery. If the issue persists, fully discharge and then fully recharge the battery to recalibrate its internal monitoring system. If the problem continues, the battery may be nearing the end of its useful life and require replacement.
