5 best sonar batteries
Long-term use of professional fish finders requires a sufficiently powerful battery. At the same time, it should be light, have a compact size, complete tightness and have a capacity that will ensure the operation of the device throughout the entire fishing process.
The best models of echo sounder batteries presented in our rating were selected based on the characteristics of the batteries and feedback from owners who used them in practice.
TOP 5 best batteries for a fish finder
5 Leoch DJW12-5.4
DJW series batteries in standby mode (UPS, alarm, etc.) will last at least five years. When working with echo sounders or other mobile devices, the resource will be reduced to 250 full cycles (it should be remembered that a deep discharge will significantly reduce the service life), but in this case, when fishing once a week, it will be enough for almost the same time period. The battery is quite compact and weighs only 1.6 kg.
Many users in their reviews express their satisfaction with the characteristics of the battery. So, using it with the Lowrance Mark 5x DSI echo sounder during the day, the battery capacity is enough for 40 hours of continuous operation. But at night, when using the backlight, this figure will already be a little more than a day. Of course, with power-hungry echo sounders, the practicality of the battery will decrease significantly, but for devices with low current consumption, choosing this battery will be the most correct decision.
4 Ventura GP 12-7
This battery does not require any maintenance during the entire operation, except for timely charging. The estimated service life is 200-250 cycles. The electrolyte is in a bound state between the plates - it is completely absorbed by the fiberglass separator, so the battery can be operated in any position.
These batteries have a wide range of applications, including as a power source for echo sounders. They are unpretentious in their work, which is important when fishing from a boat. The Ventura GP's frost resistance (down to -20 ° C) allows the battery to be used during winter ice fishing. Judging by the reviews of the owners, the batteries have proven themselves from the best side - no complaints or negative evaluations of these products have been identified.
3 CSB GP1272 F2 12V / 7.2Ah
Batteries of this brand are widely represented in the domestic market and are distinguished by the most balanced price and acceptable quality. In some reviews, users are prejudiced against products from China - the difference with the same model from Vietnam will be, albeit insignificantly, in favor of the latter. The actual experience of the confirmed operation of the CSB GP1272 F2 is a little over 5 years, and this is one of the best indicators in the rating.
A Lowrance echo sounder connected to this battery will be able to work continuously for about 30 hours - even the most exciting fishing will not last longer (the fishing process itself). The battery also has the advantage of its design. The sealed maintenance-free battery can be located on the shore or in the boat in any position - this does not affect the quality of work in any way. After fishing, the main thing is to put the battery on charge, and its resource will last for many years.
2 Fiamm FG20121A
This series of batteries from the Italian manufacturer is designed to ensure the autonomous operation of devices with a low discharge current. The batteries have a maintenance-free housing and AGM technology is used instead of liquid electrolyte. It allows you to use the battery in any position - this does not affect performance in any way, and in conditions of fishing from a boat it is an indisputable advantage.
The battery can last about 5 years if the storage rules are observed - it cannot be left discharged, and if inactivity continues for more than six months, then the battery must be recharged.The reason lies in the natural loss due to stray currents (up to 0.1% per day of the total charge). Owners who use the battery for their echo sounders, in the reviews, consider it the most unpretentious and reliable. With a properly calculated capacity, the battery will be enough for the duration of normal fishing. For example, a Humminbird PiranhaMAX with a current consumption of 0.17 A can operate from a Fiamm FG20121A for about 7 hours, after which the battery must be charged.
1 Delta HR 12-12
The Delta HR can provide up to 30 hours of continuous use with a fishfinder such as the Garmin Striker. The batteries of this series have good performance, which determines the long operating time of electronic sonars with average current consumption parameters. Thanks to the lead plates, the weight of the battery is quite sensitive - 3.9 kg. Safe operation in fishing conditions is achieved through the tightness and maintenance-free design of the battery.
Many owners, leaving reviews, indicate that Delta HR has a long service life - 5 years. The gas and adsorbed electrolyte recombination system (AGM) allows the battery to be used in any position - a useful feature for boating fishing conditions. Self-discharge of the battery within a month does not exceed 3% of the nominal capacity, and during long-term storage it is better to recharge it (once every six months is enough). Of the limitations in operation, there is only a temperature regime: due to the presence of an electrolyte in the absorber, the battery loses its performance at -20 ° C.
