Important Differences to Consider Between These Two Reels

There are many similarities between this angling equipment. But there are some differences as well. In fishing slang, it means you definitely need to check them out both before the purchase.

Ball Bearings 

In terms of ball-bearing technology, the Battle II and BG reels follow different paths. Battle II takes the lead with its rubber-sealed bearings, offering enhanced protection against saltwater conditions. On the other hand, the BG relies on regular bearings, which provide their own set of advantages. While the Battle II excels in saltwater durability with its superior rubber-sealed bearings, the BG brings its own strengths to the table, catering to different fishing environments.

Build Material

Both reel series share a common feature in their aluminum body and side plates. However, the Battle series takes it a step further by incorporating a metal rotor and bail arm, offering added strength and durability. In contrast, the Daiwa BG opts for lighter plastic materials for its rotor and bail arm. While this choice reduces weight, it also results in a slight compromise in terms of strength and long-term durability compared to the Battle series.

Retrieve Rate

Another significant contrast between the two reel series lies in their retrieve rates. The Daiwa BG outshines the other series with a notably higher retrieve rate. Surprisingly, this difference is not attributed to distinct gear ratios, as they are quite similar. Instead, it stems from the larger spool size and diameter of the BG, allowing for more lines to be wound onto the spool with each turn of the handle. This characteristic enhances the efficiency of retrieving, providing anglers with a distinct advantage on the water.

Line Capacity

The Daiwa BG boasts a larger spool size compared to the Battle II, resulting in a significantly greater line capacity. In fact, on the 5000 model, the BG offers a line capacity that is almost double that of its counterpart. This expanded line capacity empowers anglers to tackle situations requiring extensive line length, providing ample flexibility and options during their fishing endeavors.

Drag System

When it comes to this category, both series share a common feature: carbon fiber drags. This similarity ensures a reliable and consistent drag performance across the reels. However, it’s important to note that the max drag pressure can differ among models of similar sizes within each series. To make an informed decision, it is advisable to compare the specific maximum drag pressure for the size you are interested in, as it can vary and play a crucial role in your fishing requirements and target species.

Gear Ratio

In this aspect, both series exhibit a notable resemblance. However, it’s worth noting that some of the smaller sizes within the Battle II lineup feature a higher gear ratio of 6.2:1. This gear ratio is considerably higher than the corresponding sizes in the other series. The increased gear ratio offers anglers a faster retrieval rate, allowing for quick line retrieval and effective lure presentation. This distinction in gear ratio can be a crucial factor to consider when selecting a reel that aligns with your specific fishing preferences and techniques.


In terms of anti-reverse functionality, both series incorporate anti-reverse gear. However, the BG series takes it a step further by featuring an anti-reverse switch. This switch allows you to deactivate the gear, enabling you to backpedal by using the handle. On the other hand, Battle II does not possess this switch, which means backpedaling is not possible on that particular model. The inclusion of an anti-reverse switch in the BG series provides anglers with added versatility and convenience, allowing them to adapt their reel’s functionality to different fishing situations.

Let’s Talk About the Size

Both reel series are available in comparable sizes, with the Battle starting at 1000 and the BG at 1500. However, when comparing reels of the same size, there is a noticeable difference in actual size between the two series.

Take, for instance, the 5000 size in both series – the BG appears significantly larger, resembling more of a 6000 size reel. This divergence in size can have implications for anglers, influencing their preferences and choices based on the visual aesthetics and ergonomic feel of the reel in their hands.

Weight is Also an Important Factor to Consider

While there are general similarities in weight between both series, it’s important to note that Battle models tend to be a bit heavier than comparable BG models. This weight difference can be attributed to the fact that Battle reels are constructed completely with metal parts.

The use of metal components in the Battle series adds robustness and durability but may result in a slightly increased weight compared to the BG series. Anglers should consider this distinction when selecting a reel based on their desired balance, handling, and preferences during their fishing experiences.

Why Penn Battle II Is One of the Top Choices for Many Anglers?

As one of Penn’s most sought-after reel series, the Battle has garnered immense popularity for its exceptional combination of quality craftsmanship and affordability. Unsurprisingly, I’ve included it in my review of the best Penn spinning reels. This particular model is specifically engineered to tackle the demanding and corrosive environment of saltwater angling.

Its robust features, such as the metal rotor, heavy aluminum bail arm as well as sealed bearings, ensure superior durability and performance. Notably, the Battle series has proven its reliability and longevity, making it a favored choice among anglers for saltwater fishing in the USA.

However, its versatility extends to freshwater conditions as well. Numerous anglers have shared their experiences of using the same equipment for over a decade without encountering any issues. This track record of reliability and durability further solidifies its reputation as a top-notch choice for anglers in pursuit of memorable experiences while catching some of the largest freshwater species in the USA.

High Retrieve Rate Is the Key Feature That Sets Daiwa BG Model Apart From Others on the Market

Despite its seemingly simple design, the reel’s simplicity is precisely what contributes to its remarkable reliability. It’s worth noting that the ball bearings utilized in this model are identical to those found in significantly pricier, high-end reels. This shared component explains the exceptionally smooth action experienced when using the reel.

Throughout my testing, one standout feature that truly impressed me was the exceptional retrieve rate of this model. Its high retrieve rate makes it unique compared to the majority of other reel lineups. It also makes it particularly well-suited for applications that require fast lure retrieval. This attribute enhances the reel’s versatility and makes it an ideal choice for anglers seeking optimal performance during high-speed retrieval scenarios.

It Can Be Hard to Make a Decision But It Will Be Worth the Trouble

As you can see, each reel brings a distinctive set of features to the ring, ready to tackle different fishing scenarios and cater to the preferences of anglers. My personal favorite would be Penn Battle. But in the realm of fishing, there’s no definitive winner in the battle of these heavyweights. It’s up to you, the angler, to weigh your strengths, consider your individual needs, and step into the ring with the reel that best suits your fishing style.
