Echo sounders greatly facilitate the process of finding fish in the pond. However, they cannot work forever: the energy reserve in the built-in batteries is very limited, and simply forgetting to recharge them before fishing is an everyday matter. That is why it makes sense to purchase a portable battery that can be adapted to recharge the echo sounder.

In connection with this problem, the editors of Expertology magazine conducted an independent study of the segment, and selected 6 of the best batteries for fish finders. When compiling the rating, we took into account the following parameters:

  1. nominal capacity;
  2. user reviews;
  3. manufacturing quality;
  4. Compliance of working hours with the declared service life.

RDrive 6 DZM 12 electric

Rating: 4.9

RDrive 6 DZM 12 electric

The most expensive, and at the same time the highest quality battery for echo sounders in our today’s rating. RDrive 6 DZM 12 electro is a gel battery that uses Faston F2 (6.3 mm) terminals, unlike all listed competitors with F1 (4.8 mm) terminals. Despite the small overall dimensions (151x99x106 mm), its weight reaches 4.3 kg, and the nominal capacity is as much as 16 Ah.

The advantages of RDrive 6 DZM 12 electro are obvious: the gel battery perfectly tolerates discharges “to zero” and withstands up to 400 charge cycles, after which it still continues to work, albeit with less capacity. Yes, for its price you can buy 3 smaller lead-acid batteries, but the fact of uninterrupted operation and quality assurance from the manufacturer completely beat off all costs.

Advantages

  • 16 Ah capacity;

  • up to 400 charge cycles at nominal capacity;

  • small overall dimensions;

  • 100 A maximum discharge current;

  • work at temperatures from -20 to +50°С.

Flaws

  • high price.

FIAMM FG20121A

Rating: 4.8

FIAMM FG20121A

The second line of the rating goes to the extremely reliable FIAMM FG20121A battery. It was created specifically for those who appreciate the compactness and simplicity of the device and do not pursue maximum performance at the lowest price. Its nominal capacity does not exceed 1.2 Ah and during operation it always exactly corresponds to the declared value.

The overall dimensions of the FIAMM FG20121A AGM battery are 97x43x53 mm, and the weight does not exceed 0.6 kg. The standard service life, subject to operating conditions, is 5 years, and, as users note, the battery “survives” to this limit in 80% of cases. In general, an excellent option for completing an echo sounder, however, not for too long swims on the river.

Advantages

  • full compliance of the parameters with the nominal values;

  • high quality workmanship;

  • up to 5 years of uninterrupted service;

  • compactness and light weight.

Flaws

  • small nominal capacity.

WBR HR 1234W

Rating: 4.7

WBR HR 1234W

The WBR HR 1234W maintenance-free lead-acid battery is the official production source for the Leoch DJW12-9.0. In fact, the difference between these models comes down to a simple thing: ceteris paribus, their service life differs by almost half. As in the case of the replica, this model has the following operational limits: 5 years of operation in buffer mode or 260 charge cycles in cyclic use.

The overall dimensions of the WBR HR 1234W are fully consistent with the analog, and the weight is in very close limits (2.68 kg, as stated on the distributor’s website). The average rating in user reviews is 3.9 out of 5 points, the reason for which is the frequent discrepancy between the declared capacity and real values.

Advantages

  • high degree of reliability;

  • wide operating temperature range – from -40 to +60°С;

  • 24 months warranty (off. dealer);

  • the price is lower than other analogues.

Flaws

  • the actual capacity may differ from the nominal.

CSB GP1272 F2 12V/7.2AH

Rating: 4.6

CSB GP1272 F2 12V/7.2AH

The next line of the rating remains with a fairly cheap, and at the same time productive CSB GP1272 F2 battery with a capacity of 7.2 Ah. As in the case of the Leoch DJW12-9.0, the battery life is set for several operating modes: cyclic (260 discharge and charge cycles) and buffer (no more than 5 years). Overall dimensions are averaged, and the weight does not exceed 2.4 kg.

One of the advantages of CSB GP1272 F2 is the place of production. The batteries are not Chinese, but Vietnamese, and according to preliminary data on manufacturing, no more than 4% of the finished product is rejected at the sales stage. For comparison, Chinese batteries can be rejected in the amount of 10% of the total mass produced. As we said above, this lead-acid battery model is quite cheap and is sold in almost all specialized stores.

Advantages

  • reliability – fulfills at least the warranty period;

  • low price.

Flaws

  • The actual capacity of purchased batteries may be lower than stated.

Delta HR 12-5.8

Rating: 4.5

Delta HR 12-5.8

The Delta HR 12-5.8 is a slightly more “definite” fishfinder battery than the Leoch DJW12-9.0. Characteristics are modest, but the element of surprise is completely excluded – the user will always know how much time is left before the moral exhaustion of the battery. Among the regulated characteristics, 8 guaranteed years of service can be noted, as well as 5.8 Ah of rated capacity.

Among the advantages of Delta HR 12-5.8 are the overall dimensions. Parameters 90x70x101 look much better than the previous representative of the rating, and the weight does not exceed 1.95 kg. The temperature indicators are not standard, but in general they cover all the needs for operation in conjunction with an echo sounder: it is unlikely that anyone would think of using the device at a temperature of -20 ° C.

Advantages

  • made using AGM technology;

  • relatively low price;

  • 8 years of service;

  • compact and fairly light lead-acid battery.

Flaws

  • not detected.

Leoch DJW12-9.0

Rating: 4.4

LEOCH DJW12-9.0

Lead-acid AGM battery with a capacity of 9 Ah. An excellent option for completing an echo sounder in long swims – not the smallest, but not very large either. Its overall dimensions are 151x65x95 mm, and the weight does not exceed 2.75 kg.

According to manufacturers, the average service life of Leoch DJW12-9.0 is from 5 to 8 years when operating in buffer mode. If we take into account the cyclic method of operation, then the battery can withstand up to 200-250 charge / discharge cycles. Therefore, the terms of use will vary widely from the frequency of fishing trips and their duration.

Advantages

  • 9 Ah capacity;

  • acceptable price;

  • operates in the temperature range from -40 to +60°C (when discharging).

Flaws

  • withstands up to 200-260 charge and discharge cycles.
