pulseEKKO PRO Battery Care


SmartCart uses a Sensors & Software SmartCart System battery to power the DVL and separate batteries to power the transmitter and receiver. The pulseEKKO PRO TR1000 uses a belt battery to power the DVL, transmitter, and receiver.

DVL battery

is a 7 to 15 Amp-hour, 12-volt sealed lead acid battery that is protected by a 10 Amp fuse. This prevents damage in case of a short circuit. Though seldom required, the fuse may burn out or blow. A replacement fuse is kept inside the battery box and can be used to replace a bad fuse.

Transmitter and Receiver operate

on two 12 volt sealed batteries. The transmitter may run about 4 hours while the receiver will run about 8 hours on a pair of batteries.

The pulseEKKO PRO antenna and DVL contains a voltage monitoring circuit.

Once the voltage drops to 10.2 volts, the unit will automatically power down. If this occurs, recharge the battery before attempting to complete the GPR survey. Charge batteries as soon as discharged. When a battery is put on the charger, the Fast Charge LED will light up. If it does not light up after six hours or charging, the battery should be replaced. After eight hours, the Fast Charge LED will normally go out. Do not remove the battery as a trickle charge is being applied. A battery takes a minimum of twelve hours to fully charge.

  • Do not allow them to remain in a discharged state.
  • Do not mix charged and discharged batteries.

Run Time

varies with temperature and usage. Cold weather can greatly reduce battery life. From a practical standpoint, it is usually many hours before recharging is necessary. A second set of pulseEKKO PRO batteries may be needed for long field days or if the battery cannot be charged during breaks. The best practice is to always make sure to charge the batteries overnight! pulseEKKO PRO battery maintenance is of utmost importance. Batteries must be kept in a charged state to ensure a long and reliable life.

pulseEKKO PRO Battery Rules:

1. Do not allow sealed lead acid batteries to be left in a discharged state. Regularly charge batteries.

2. When the pulseEKKO PRO is not being used, unplug the battery cable. The system uses about 0.1 amps and slowly drains the battery.

3. When not in use, charge the batteries. Fast charging a fully discharged battery can take approximately 12 to 14 hours from start to finish.

4. Charge batteries at room temperature.

5. Before storing a battery make sure it is fully charged. Store the battery in a cool place. 50 degrees Fahrenheit is ideal. Do not allow the battery to freeze.

6. If a battery becomes discharged or is left discharged, connect it to the charger. The fast charge LED will not go on immediately. If the fast charge LED does not light in six hours, the battery should be replaced.

DVL Internal Battery:

The DVL internal battery is dependent on the Smart System. If the Smart System is not periodically turned on for an extended period of time such as a survey, the DVL internal battery will discharge. Once a DVL internal battery becomes discharged, the DVL time and date will reset to January 1, 1988 at 12:00 PM. This is a good indication that the battery was too low to maintain the internal functions.

Recharge the DVL internal battery by running the Smart System for at least an hour.
