Are Cheap Trolling Motor Batteries Worth It?

Are Cheap Trolling Motor Batteries Worth It? A Deep Dive

When outfitting a boat for fishing, the temptation to cut costs is understandable. Trolling motor batteries, particularly deep-cycle marine batteries, can represent a significant investment. This leads many anglers to wonder: are cheap trolling motor batteries a viable option? The answer, as with most things, is nuanced and depends on your specific needs and expectations.

Understanding the Trade-Offs:

The primary allure of cheap trolling motor batteries is, of course, the lower price tag. However, this initial saving often comes with significant trade-offs that can impact performance, longevity, and overall cost-effectiveness.

1. Capacity and Run Time:

• The Problem: Cheap batteries frequently underperform their advertised amp-hour (Ah) ratings. This means you’ll likely experience shorter run times on the water compared to higher-quality batteries.
• Real-World Impact: This can be particularly problematic for anglers who spend long days on the water or fish in areas with strong currents. You might find yourself running out of power prematurely, limiting your fishing time and potentially leaving you stranded.
• Testing: Many cheaper batteries do not go through the rigorous testing that higher end batteries go through. This is where the difference in real world amp hour ratings are found.

2. Longevity and Lifespan:

• The Problem: Lower-quality materials and construction can significantly shorten the lifespan of cheap batteries. They may be more susceptible to sulfation, corrosion, and damage from vibration.
• Real-World Impact: You’ll likely need to replace cheap batteries more frequently, which can negate any initial cost savings.
• Cycles: Deep cycle batteries are rated for the number of discharge and recharge cycles. Cheap batteries have far less cycles than a quality battery.

3. Performance and Consistency:

• The Problem: Cheap batteries may exhibit inconsistent performance, with fluctuating voltage and power output. This can affect the performance of your trolling motor and make it difficult to maintain a consistent speed or position.
• Real-World Impact: This can be frustrating for anglers who rely on precise boat control for effective fishing.
• Internal Resistance: Cheaper batteries can have higher internal resistance, which means that the battery will not deliver power as efficiently as a higher quality battery.

4. Maintenance and Reliability:

• The Problem: Some cheap batteries may require more frequent maintenance, such as checking and refilling water levels (in flooded lead-acid batteries). They may also be more prone to leaks and spills.
• Real-World Impact: This can be inconvenient and time-consuming, and potentially create safety hazards.
• BMS (Battery Management System): If discussing LiFePO4 batteries, cheap batteries will have cheaper BMS systems, that can fail, and cause damage to the battery.  

5. Warranty and Customer Support:

• The Problem: Cheap batteries often come with limited or no warranties, and customer support may be lacking.
• Real-World Impact: If your battery fails prematurely, you may be left with no recourse.

When Might a Cheap Battery Be Acceptable?

There are a few scenarios where a cheap trolling motor battery might be a reasonable option:

• Occasional Use: If you only use your trolling motor for short periods on calm waters, a cheap battery might suffice.
• Backup Battery: A cheap battery could serve as a backup in case your primary battery fails.
• Very Tight Budget: If you’re on an extremely tight budget and absolutely cannot afford a higher-quality battery, a cheap battery is better than nothing. However, be prepared for the potential drawbacks.

The Long-Term Cost:

It’s essential to consider the long-term cost of your investment. While a cheap battery may save you money upfront, it could end up costing you more in the long run due to frequent replacements, reduced performance, and potential damage to your trolling motor.

The Verdict:

In most cases, investing in a higher-quality trolling motor battery is worth the extra cost. You’ll enjoy longer run times, better performance, increased reliability, and a longer lifespan. This will ultimately save you money and frustration in the long run.

Recommendations:

• If possible, invest in AGM or LiFePO4 batteries. LiFePO4 batteries, while more expensive, are becoming more common and affordable, and provide the best long term value.
• Research reputable brands and read reviews before making a purchase.
• Consider your specific needs and fishing style when choosing a battery.
• Prioritize quality and reliability over price.

By making an informed decision, you can ensure that your trolling motor battery provides the power and performance you need for a successful and enjoyable fishing experience.
