3.Weize Deep Cycle AGM 12 Volt 100Ah Battery
Price: $ 169.99 | Review: 4.5 | Weight: 57 Pounds
The Weize Deep Cycle AGM 12V 100Ah battery is a solid budget-friendly option if you need a reliable deep-cycle battery for your trolling motor, marine gear, solar setup, or RV. It doesn’t have the flash of lithium types, but for those who want steady performance, less fuss, and a good price, it delivers more than you might expect.
What it does well: It’s built with AGM sealed lead-acid tech, so no worries about acid leaks or topping off water. Weize touts a low self-discharge rate (around 1-3% per month), which means you can let it sit for a while and it won’t drain fast. The max discharge current is high—about 1150A (for 5 seconds)—so it can handle a good burst of demand, which helps if your motor pulls hard, or you have accessories. It’s also made to operate over a wide temperature range, so it works even in colder or warmer conditions.
Where it falls short: Because it’s AGM lead-acid, it’s heavy—moving it around or fitting it in tight spaces can be painful. Its usable capacity is less than what a lithium battery can safely give (you’ll want to avoid deep discharges for AGM to protect lifespan). The warranty is just 1 year, so long-term protection is limited. Also, charging times and efficiency are lower than what you get with lithium.
Pros:
- Sealed AGM design: no leaks, low maintenance
- Low self-discharge: holds charge well during storage
- High burst current: good for sudden load demands
- Operates across a wide temperature range
- Strong price per amp-hour compared to many AGM batteries
Cons:
- Heavy and bulky — less ideal for small boats or portability
- Limited usable capacity if you want to preserve battery life
- Slower charging and less efficient compared to lithium batteries
- Short warranty period
- Over many cycles, performance declines faster than high-end lithium batteries
4.Newport 12V 50Ah Deep Cycle Marine Battery
Price: $ 139.99 | Review: 4.5 | Weight: 30 Pounds
The Newport 12V 50Ah Deep Cycle Marine Battery is a sealed-AGM (absorbed glass mat) design aimed at small boats, trolling motors, or powering marine electronics. At about 30 lbs, it strikes a balance between portability and power — light enough to move, but still with enough juice for longer fishing sessions or moderate accessories. Its 50Ah capacity delivers a decent run time in everyday use, and the sealed design means it’s spill-proof and relatively low maintenance, which angler friendly. The housing is built tough, and it’s designed to handle vibration, exposure to marine conditions, and the usual wear and tear of days on the water.
If you push the battery hard (high speed / high thrust), you’ll notice its limits — you can’t expect the same runtime or performance as larger capacity or lithium batteries. But for what it’s made for — moderate trolling, lights, fish finders, etc. — it does its job well.
Pros
- 50Ah is enough for many mid-day trips: trolling motor + basic electronics
- Sealed AGM design: no leaks, low maintenance
- Vibration resistance and rugged build suitable for marine conditions
- Relatively lightweight (for an AGM) to make installation & handling easier
- Decent value for boaters who want reliability without going lithium
Cons
- Heavier and bulkier compared to lithium batteries of similar capacity
- Runtime drops fast under heavier load or long high-thrust use
- Longer charging times vs lithium
- AGM batteries typically degrade more over time (if deeply discharged often)
- Higher upfront cost than basic flooded lead-acid batteries
5.VMAX MR127
Price: $ 269.96 | Review: 4.5 | Weight: 68 Pounds
The VMAX MR127-100 is a serious deep-cycle AGM battery built for continuous marine or trolling motor use. With a full 100Ah capacity at 12 volts, it delivers solid performance for longer trips or when running accessories like fish finders, lights, or livewells. It’s heavy duty — made with rugged plates and thick internal construction to resist vibration and demanding loads. Maintenance-free design means you won’t need to worry about topping up water or dealing with spills. It fits standard battery boxes and is popular among anglers who want reliable power without going lithium, especially if weight is less of an issue.
It’s not perfect — because it’s AGM, it’s heavier and bulkier than lithium. Deep discharges will wear it down faster, and its rate of self-discharge and charging speed are less forgiving than newer lithium options. But if you’re outfitting a solid bass boat, pontoons, or similarly sized craft and want a battery that can take repeated use, the MR127 is up to the task.
Pros
- High capacity (100Ah) gives good runtime for trolling motors + accessories
- Rugged build and durable internal components — handles vibration and hard use well
- Maintenance-free sealed AGM — no watering or spillage concerns
- Fits in Group 27 battery size — drop-in for many setups
- Strong reserve capacity and pulse current for short bursts
Cons
- Heavy — makes it harder to carry, install, or reposition
- Slower charging compared to lithium batteries
- Less usable life if frequently deeply discharged
- Bulky size means space constraints in smaller boats or kayaks
- Higher weight also impacts how boats perform (balance, launch effort, etc.)
Buying Guide: How to Choose the Right Trolling Motor Battery
Picking the best trolling motor battery isn’t just about grabbing the biggest one you can find. It’s about matching the right battery to your boat, your motor, and your fishing style. Here’s a full breakdown of what you should consider before making a decision.
1. Battery Types
- Flooded Lead-Acid (Wet Cell): These are the most affordable and widely available. They work fine for casual anglers but require maintenance and can spill if tipped. They’re also heavier and usually have a shorter lifespan.
- AGM (Absorbed Glass Mat): A sealed, maintenance-free version of lead-acid that’s tougher against vibration and easier to handle. They cost more but are a dependable choice for anglers who fish often.
- Lithium (LiFePO₄): The premium option. Lightweight, long-lasting, and able to discharge more deeply. They cost more upfront but provide better performance, faster charging, and thousands of charge cycles. Perfect for serious anglers or kayak fishermen who need to save weight.
2. Voltage
Your motor’s voltage requirement determines what battery you need.
- Small motors usually run on 12V.
- More powerful motors may need 24V or 36V systems, which means using multiple batteries in series or a dedicated higher-voltage lithium battery.
Always match the voltage to your trolling motor or you risk poor performance or damage.
3. Amp-Hours (Ah) & Runtime
The higher the amp-hour rating, the longer your battery will last on the water. For example:
- 50Ah might power a motor for a few hours.
- 100Ah can give you all-day performance at moderate speeds.
Keep in mind that traditional lead-acid batteries shouldn’t be drained below 50% regularly, while lithium batteries can safely use 80-100% of their capacity.
4. Thrust & Motor Load
Bigger trolling motors with higher thrust levels pull more current, especially at top speeds or in strong wind and current. If you run your motor at full throttle often, you’ll need a larger battery or even a lithium upgrade to keep up.
5. Size & Weight
Batteries come in standard group sizes (24, 27, 31, etc.). Always check that the one you buy fits your battery compartment.
- Lead-acid and AGM batteries are heavy and can weigh down smaller boats.
- Lithium batteries are much lighter and easier to transport, which is a huge benefit for kayaks and jon boats.
6. Durability & Maintenance
- Lead-acid wet cells need regular maintenance (checking fluid levels, cleaning terminals).
- AGM and lithium are sealed, spill-proof, and vibration-resistant, making them better for rough waters and saltwater conditions.
- Look for rugged casings, corrosion-resistant terminals, and safety features like built-in protection against overcharging.
7. Charging
Always use the right charger for your battery type.
- Flooded and AGM batteries use traditional marine chargers.
- Lithium batteries require a lithium-compatible smart charger for safe, fast, and full charging.
Proper charging habits will extend your battery life — don’t let it sit discharged for too long.
8. Fishing Environment
- Cold weather: Lead-acid batteries lose performance in low temperatures, while lithium holds up better but may have charging restrictions in extreme cold.
- Saltwater fishing: Look for sealed, marine-grade batteries that resist corrosion and vibration.
9. Warranty & Long-Term Value
While lead-acid and AGM batteries typically last 3–5 years, lithium batteries can last 8–10 years or more. The upfront cost is higher, but the long-term value often makes lithium the cheaper option over time. A strong warranty also adds peace of mind.
10. Practical Tips
- Always follow your trolling motor manufacturer’s recommendations.
- If you run multiple batteries, make sure they are the same type and age for best performance.
- Plan for extra capacity to handle wind, current, and accessories like fish finders or lights.
- For kayaks and smaller boats, prioritize lighter batteries to avoid dragging your performance down.
