6 best sonar batteries

* Review of the best according to the editors of ecdfburma.org. About the selection criteria. This material is subjective, is not an advertisement and does not serve as a guide to the purchase. Before buying, you need to consult with a specialist.

Echo sounders greatly facilitate the process of finding fish in a pond. However, they cannot work forever: the energy supply in the built-in batteries is very limited, and just 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 Ecdfburma magazine conducted an independent study of the segment, and selected 6 of the best batteries for echo sounders. When making the rating, we took into account the following parameters:

  1. rated capacity;
  2. user reviews;
  3. workmanship;
  4. compliance of working time with the declared service life.

RDrive 6 DZM 12 electro

Rating: 4.9

The most expensive and at the same time the best quality battery for echo sounders in our rating today. RDrive 6 DZM 12 electro is a gel battery that uses Faston F2 terminals (6.3 mm), unlike all of the above competitors with F1 terminals (4.8 mm). 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 the RDrive 6 DZM 12 electro are obvious: the gel battery perfectly transfers 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 repels all costs.


  • 16 Ah capacity;
  • up to 400 charge cycles with a nominal capacity indicator;
  • small overall dimensions;
  • 100 A maximum discharge current;
  • work at temperatures from -20 to + 50 ° C.


  • high price.


Rating: 4.8

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 under observance of the operating conditions is 5 years, and, as users note, the battery in 80% of cases "lives" to this limit. In general, a great option for picking an echo sounder, however, is not for too long swims in the river.


  • full compliance of parameters with nominal values;
  • high quality workmanship;
  • up to 5 years of uninterrupted service;
  • compactness and light weight.


  • small nominal capacity.

WBR HR 1234W

Rating: 4.7

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

The overall dimensions of the WBR HR 1234W are fully consistent with the analogue, and the weight is in very close range (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 the real values.


  • high degree of reliability;
  • wide range of operating temperature - from -40 to + 60 ° С;
  • 24 months warranty (official dealer);
  • the price is lower than for other analogues.


  • Actual capacity may vary.

CSB GP1272 F2 12V / 7.2AH

Rating: 4.6

The next line of the rating remains for a rather cheap and at the same time productive CSB GP1272 F2 battery with a capacity of 7.2 Ah. As with 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). The overall dimensions are averaged, and the weight does not exceed 2.4 kg.

One of the advantages of the CSB GP1272 F2 is the place of production. The batteries are not Chinese, but Vietnamese, and according to preliminary manufacturing data, 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 model of a lead-acid battery is quite cheap and is sold in almost all specialized stores.


  • reliability - fulfills at least the warranty period;
  • low price.


  • actual battery capacity may be lower than stated.

Delta HR 12-5.8

Rating: 4.5

The Delta HR 12-5.8 is a slightly more “defined" sonar battery than the Leoch DJW12-9.0. The characteristics are modest, but the element of surprise is completely excluded - the user will always know how much time is left before the battery is exhausted. Among the regulated characteristics, 8 guaranteed years of service, as well as 5.8 Ah of nominal capacity, can be noted.

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. Temperature indicators are not standard, but on the whole they cover all the operational needs in conjunction with an echo sounder: it is unlikely that anyone will think of using the device at a temperature of -20 ° C.


  • made by AGM technology;
  • relatively low price;
  • 8 years of service;
  • compact and fairly light lead-acid battery.


  • not detected.

Leoch DJW12-9.0

Rating: 4.4

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

According to manufacturers, the average life of Leoch DJW12-9.0 is from 5 to 8 years when working in buffer mode. If we take into account the cyclic method of operation, 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.


  • 9 Ah capacity;
  • acceptable price;
  • It works in the temperature range from -40 to + 60 ° С (during discharge).


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