Why Your Predator Generator 8750 Needs the Right Battery
Think of the battery in your Predator Generator 8750 as the ignition switch for your power source. It’s not about providing the main electricity when the generator is running; instead, its primary job is to kickstart the engine. When you press that start button or pull the cord, it’s the battery that sends the initial surge of power to the starter motor, getting the engine to fire up. Without a healthy battery, your generator is essentially useless, no matter how much fuel you have.
A good battery ensures a quick and reliable start. This is crucial in emergencies when every second counts. Imagine a power outage during a storm; you need your generator to fire up instantly without fuss. An old, weak, or incorrect battery can lead to slow cranking, missed starts, or even damage to the starter system over time. Choosing the correct battery specifically designed for your Predator Generator 8750 ensures it has the right voltage, amperage, and physical size to do its job effectively and efficiently.
Understanding Generator Battery Basics
Generators, especially portable ones like the Predator 8750, typically use a 12-volt (12V) sealed lead-acid (SLA) battery. These are a popular choice for a few reasons:
- Reliability: They are known for being dependable for starting applications.
- Low Maintenance: Being sealed, they don’t require you to check or add water like older car batteries.
- Cost-Effective: They offer a good balance of performance and price.
- Vibration Resistance: They can handle the jostling that comes with portable generators.
When looking for a replacement, you’ll often see terms like “starting battery” or “cranking amps” (CA) and “cold cranking amps” (CCA). For a generator, the cranking amps are the most important. This rating tells you how much power the battery can deliver for a short burst to start an engine. While your Predator 8750 doesn’t need the massive CCA of a car battery, it still needs enough juice to spin that engine over effectively.
Key Battery Specifications to Look For:
- Voltage: Almost always 12V for generators of this size.
- Type: Sealed Lead-Acid (SLA) is standard.
- Capacity (Ah – Ampere-hours): This indicates how long the battery can deliver a certain amount of current. A higher Ah generally means more capacity, but for starting, the cranking amps are more critical.
- Cranking Amps (CA) / Cold Cranking Amps (CCA): This is the most vital spec for starting. Aim for a battery that meets or slightly exceeds the manufacturer’s recommendation.
- Physical Dimensions: The battery must fit in the designated battery compartment on your generator.
- Terminal Type and Location: Ensure the terminals (where you connect the cables) are the same type and in the same place as your old battery.
Identifying the Exact Battery for Your Predator Generator 8750
The most foolproof way to find the right battery is to check your generator’s owner’s manual. This document will clearly state the recommended battery type, specifications, and sometimes even a part number. If you can’t find your manual, don’t fret. Several reputable online resources and battery retailers have compatibility checkers where you can input your generator’s make and model (Predator Generator 8750) to see a list of compatible batteries.
Physically inspecting your current battery is also a great strategy. Most batteries will have labels with their specifications printed on them. Jot down the voltage, Ah rating, CA/CCA rating, and importantly, the physical dimensions (length, width, height) and terminal type. This information is invaluable when shopping.
When searching online, use specific terms like “battery for Predator Generator 8750” or “Predator 8750 generator battery specifications.” You’ll likely find that a common size and rating is recommended. Many users find that a standard 12V, 18Ah to 35Ah sealed lead-acid battery with sufficient cranking amps is a suitable replacement.
Commonly Recommended Battery Types and Specs
While the exact OEM part number might be specific, many aftermarket batteries perform excellently. A popular and often compatible choice is a 12V 35Ah battery. The 35Ah rating provides ample reserve power, and these batteries typically have enough cranking amps to start the Predator 8750 reliably. Always double-check dimensions to ensure a proper fit.
For example, many users opt for batteries similar to the X2Power SLI35AGMD (or similar BCI Group Size 35 AGM batteries), though you must verify the physical fit with your specific generator’s battery tray. AGM (Absorbent Glass Mat) batteries are an excellent upgrade over standard flooded SLA batteries, offering better vibration resistance and longer life. However, standard SLA batteries will also work perfectly fine.
Where to Buy Your Generator Battery
You have several convenient options for purchasing a replacement battery:
- Online Retailers: Websites like Amazon, Batteries Plus, specific battery dealer sites, and even manufacturer direct often have a wide selection. Buying online can give you access to more options and competitive pricing. Look for sellers with good reviews and clear return policies.
- Local Battery Stores: These specialized shops are a fantastic resource. Their staff are battery experts and can help you find the exact match or a suitable alternative. They often carry top brands and can offer advice specific to your needs.
- Big Box Stores: Larger general retailers like Walmart or hardware stores may carry common generator battery sizes, especially during hurricane season or peak demand times. However, selection might be more limited.
- Generator Part Suppliers: Websites that specialize in generator parts and accessories are another reliable source, often stocking OEM or quality aftermarket batteries.
When purchasing, always consider the warranty offered with the battery. A longer warranty period can provide peace of mind.
Step-by-Step Guide: Replacing Your Predator Generator Battery
Replacing the battery yourself is a straightforward process that most people can handle with basic tools. Safety first is key!
Tools You’ll Likely Need:
- Safety glasses
- Work gloves
- Socket wrench set (with a socket that fits your battery terminal nuts, often 10mm or 13mm)
- Wire brush or terminal cleaner
- Anti-corrosion spray or grease (optional, for battery terminals)
- New battery (correct specifications and size)
Procedure:
- Ensure Generator is Off and Cool: Make absolutely sure the generator is turned off, unplugged from any load, and has had time to cool down if it was recently running.
- Locate the Battery: The battery is usually housed in a compartment accessible from the side or near the pull-start mechanism. It might be covered by a plastic shroud or a small panel. Consult your manual if you’re unsure.
- Disconnect the Old Battery: This is the most critical safety step. Always disconnect the negative (-) terminal first. This is typically the black cable. Use your socket wrench to loosen the nut on the terminal clamp and carefully remove the cable. Then, disconnect the positive (+) terminal (usually red cable). This prevents accidental short circuits.
- Remove the Old Battery: Once the cables are disconnected, you may need to remove a battery hold-down bracket or clamp. Some are bolted, while others are spring clips. Carefully lift the old battery out. Batteries can be heavy, so be mindful of your back!
- Clean Battery Terminals and Cables: Use a wire brush or a dedicated terminal cleaner to thoroughly clean the battery cables and the battery tray where the new battery will sit. Remove any corrosion or debris for a good electrical connection.
- Install the New Battery: Carefully place the new battery into the tray, ensuring it’s oriented correctly so the terminals align with the cables. Reinstall the hold-down bracket or clamp to secure the battery firmly in place.
- Connect the New Battery: Connect the positive (+) terminal cable first, then the negative (-) terminal cable. Tighten the terminal nuts securely with your socket wrench. Ensure the cables are snug but do not overtighten.
- Apply Terminal Protection (Optional): A light application of anti-corrosion spray or dielectric grease on the terminals can help prevent future corrosion and ensure a good connection.
- Close Up and Test: Replace any covers or panels you removed. Now, it’s time to test! Try starting your generator. It should crank over more readily with the new battery.
Important Safety Note: Lead-acid batteries contain corrosive acid and can release explosive hydrogen gas when charging or discharging. Always work in a well-ventilated area, wear safety glasses and gloves, and avoid sparks or open flames near the battery. If you are uncomfortable with any part of this process, it’s best to have a qualified technician perform the replacement.
Maintaining Your Generator Battery for Longevity
A little bit of care can go a long way in extending the life of your generator’s battery.
- Regular Testing/Starting: It’s a good practice to start your generator periodically (e.g., once a month) for about 10-15 minutes. This not only keeps the engine lubricated but also charges the battery, preventing it from sitting in a discharged state for too long. A “trickle charger” or “battery maintainer” designed for 12V SLA batteries can also be used if the generator is stored for extended periods.
- Keep Terminals Clean: Inspect the battery terminals occasionally for signs of corrosion (a white or bluish powdery substance). Clean them promptly as described in the replacement guide.
- Avoid Deep Discharges: Don’t let the battery go completely flat. While generators aren’t designed for deep cycling like some RV batteries, repeatedly trying to start a stubborn engine can drain it significantly.
- Proper Storage: If you store your generator for long periods (more than a couple of months), connect it to a battery maintainer. If you cannot, consider removing the battery and storing it in a cool, dry place, and check its charge every few months, topping it up if necessary.
- Temperature Extremes: Avoid storing the generator or its battery in extreme heat or cold. High temperatures can accelerate battery degradation, while extreme cold can reduce its starting power.
Troubleshooting Common Battery Issues
Here are some common problems you might encounter with your generator battery and how to address them:
| Problem | Possible Cause | Solution |
|---|---|---|
| Generator won’t start, slow cranking. | Weak or dead battery. | Test battery voltage. If low, try charging. If it won’t hold a charge, replace it. |
| Corroded battery terminals. | Sulfuric acid fumes escaping (less common with sealed batteries) or external factors. | Clean terminals with a wire brush and baking soda/water solution. Apply anti-corrosion spray. |
| Battery swelling or leaking. | Overcharging, internal damage, or extreme heat. | Do not use. Replace immediately. Dispose of properly. Check charging system if applicable. |
| Generator starts sometimes, but not always. | Intermittent connection at terminals or a battery nearing the end of its life. | Check and tighten all cable connections. Clean terminals. If consistent, replace battery. |
| Battery is hot to the touch during charging. | Normal for some charging, but excessive heat can indicate a problem. | If extremely hot, disconnect charger and let it cool. If it persists, the battery might be failing or charging system is faulty. |
For a comprehensive understanding of battery maintenance and safety, resources from the U.S. Environmental Protection Agency (EPA) on battery safety can be very informative.
When to Consider a Battery Upgrade
While a standard SLA battery will get the job done, there are situations where upgrading might be beneficial:
- Increased Reliability in All Conditions: AGM batteries, for instance, perform better in extreme temperatures (both hot and cold) and are more resistant to vibration, which can be common with generators.
- Longer Lifespan: High-quality AGM batteries often have a longer service life than standard flooded SLA batteries, meaning you’ll replace them less often.
- Improved Safety: AGM batteries are spill-proof and more robust, offering an extra layer of safety, especially if your generator is moved around frequently.
When upgrading, ensure the new battery’s physical dimensions still fit your generator’s battery compartment, and that it has sufficient cranking amps. A 12V 35Ah AGM battery is often a readily available and excellent upgrade option for the Predator 8750.
