Description of the operation of devices with the index “A”
6.1. If necessary, correct the zero position of the dial indicator using its mechanical compensator.
6.2. Set the current regulator to the minimum position.
6.3. Tighten the wires included with the charger securely, taking into account the color.
6.4. Connect, strictly observing the polarity, the alligator clips to the battery terminals. The positive terminal of the battery is connected with a red wire, the negative terminal of the battery is connected with a black wire to the black terminal of the charger.
6.5. Connect the charger to the mains.
6.6. By turning the current regulator to the right, set the maximum charging current in accordance with the instructions for the specific battery. In the absence of instructions, we recommend setting the maximum charging current to approximately 0.1 of the battery’s nameplate capacity (for a battery with a capacity of 55 A*hour, set the current to 5.5 A).
6.7. On partially discharged batteries and in case of some battery malfunctions (severe sulfation of the plates, internal break between the battery banks), when the battery does not accept a charge, it is possible that you will not be able to set the recommended charging current. In this case, we recommend setting the charging current to 0.03 A from the battery’s nameplate capacity - this charging mode promotes the resorption of sulfate, but lengthens the charging time.
6.8. If it is impossible to set the desired charging current, check the voltage on the battery with the charger connected and the current regulator on the charger set to the right position. If the voltage matches the charger limit voltage (14.9 ± 0.1 V), the battery is either fully charged or faulty.
6.9. During charging, the voltage on the battery increases and reaches the limiting voltage. After this, the charger begins to reduce the charging current. A typical characteristic of the charging mode of a 12-volt battery at the specified maximum current and rated voltage (for modifications “d”) is shown in Table 2.
Table 2.
| Output voltage, V | Output current, A | |
| Pendant-707 | Pendant-715 | |
| 0 … 12 | 7 ± 1,5 | 15,0 ± 1,5 |
| 12,0 … 14,5 | 6,5 ± 1,0 | 14,0 ± 1,5 |
| 14,6 … 15,0 | smooth decline | |
6.10. The battery charging process can be completed 3 hours after the charging current drops to a value of 0.01 of the battery capacity (for a 55 A*hour battery, this is a current of 0.55 A).
6.11. After charging the battery, disconnect the device from the power supply, and only then the connecting wires from the battery. To avoid shorting the battery and reduce sparking, first disconnect the black wire from the charger terminal, and only then the red clamp from the positive terminal of the battery, and then the wire from the red terminal of the device.
6.12. If you do not intend to disassemble the battery charging station, take measures in advance to prevent accidental short-circuiting of the connectors during subsequent use.

Description of the operation of devices with the index “d”.
7.1. Set the current and voltage controls to the far left position.
7.2. Without connecting the output wires to the device, connect the charger to the power supply.
7.3 Use the voltage adjustment knob to set the required limiting voltage - the end-of-charge voltage of the battery. In subsequent actions, be careful not to change the production settings.
7.4. Unplug the charger.
7.5. Securely screw the wires included with the charger to the output terminals, taking into account the color.
7.6. Connect, strictly observing the polarity, the alligator clips to the battery terminals. The positive terminal of the battery is connected with a red wire, the negative terminal of the battery is connected with a black wire to the black terminal of the charger.
7.7. Connect the charger to the mains.
7.8. By turning the current regulator to the right, set the maximum charging current in accordance with the instructions for the specific battery. In the absence of instructions, we recommend setting the maximum charging current to approximately 0.1 of the battery’s nameplate capacity (for a battery with a capacity of 55 A*hour, set the current to 5.5 A).

7.10. If it is impossible to set the desired charging current, check the voltage on the battery with the charger connected and the current regulator on the charger set to the right position. If the voltage corresponds to the limiting voltage you set, and the charging current is low, the battery is either fully charged or faulty.
7.11. During charging, the voltage on the battery increases and reaches the limiting voltage. After this, the charger begins to reduce the charging current. A typical current-voltage characteristic is shown in Table 2.
7.12. The battery charging process can be completed 3 hours after the charging current drops to a value of 0.01 of the battery capacity (for a 55 A*hour battery, this is a current of 0.55 A).
7.13. After charging, disconnect the device from the power supply, and only then the connecting wires from the battery.

Using chargers as a power supply.
8.1. Chargers models Kulon-707A , Kulon-715A can be used as a power supply with a fixed voltage of 15.0 V.
8.2. Chargers of the models Kulon-715 d , Kulon-707 d can be used as an adjustable power supply with an output voltage from 6.0 to 15.0 V. To set the voltage, you must disconnect the load from the output terminals and set the voltage regulator to the required value. Then set the current regulator to the minimum position (to the left). Connect the load and set the current limit with the current regulator until the voltage stabilizes. If the load is variable in nature, increase the limiting current so that at maximum power take-off, the voltage across the load does not drop. For safety reasons, we do not recommend always setting the maximum current for which the device is designed, because in the event of a short circuit in the load, this will lead to more severe consequences.
8.3. When using the charger as a power supply, avoid short circuiting the output wires.
Reviews
The most reviews on the Internet can be found about pendant chargers of the 707 and 715 series. Owners are attracted, first of all, by the good combination of price and quality. Among the advantages, users also note the low weight and compact dimensions of these chargers. Those who are encountering charging a car battery for the first time liked the fact that the device can operate in fully automatic mode. That is, I set it and forgot it, so as not to fool myself.
Those who often have to charge high-capacity batteries (for example, from trucks) rated the Pendant 715d device positively. This model provides a current of up to 15 amperes at the start of charging, which significantly reduces the process. Many users liked the display of information about the charging process on the liquid crystal display (for models with such a display).
There are practically no reviews on the use of the Pendant charger with gel and AGM batteries. Therefore, it is not yet possible to form an objective opinion about the use of chargers with these types of batteries.
There are also negative reviews regarding starter battery chargers manufactured by Balsat. In general, negative and positive reviews are divided in a ratio of 20 to 80. In negative reviews, users usually point out the unreliability of Coulomb devices. For some owners who left similar reviews, the charger failed within about 2-3 years.
Problems were also associated with the lack of polarity reversal protection. Some users write that they confused the polarity. As a result, the “charger” failed.
Recommendations for use.
9.1. We recommend charging the battery at room temperature, because... In a cold state, the battery's ability to accept a charge sharply decreases (internal resistance increases).
9.2. To quickly charge the battery, it is allowed to charge at the maximum possible current, however, for a more complete charge of the battery, we recommend setting the charging current to 1/10 of the battery capacity. However, maintenance-free batteries (without top-up plugs) are more critical to the increase in voltage during charging and therefore, during the charging process, when the voltage increases to the limit value, we recommend reducing the charging current.
9.3. When storing the battery for a long time without recharging, before using the battery, we recommend charging the battery with a low current (1/20 ... 1/30 of the battery capacity). When storing a battery for a long time, you need to take into account that the battery self-discharges, so every 2-3 months we recommend fully charging the battery.
9.4. Old batteries have a reduced ability to accept charge, so during the charging process the charging current drops quickly or the charging current does not reach the maximum value.
9.5. During the first 15 minutes of operation of the charger, thermal conditions stabilize. We recommend not leaving the workplace unattended during this period and, if necessary, adjust the charging current.
9.6. If thermal protection periodically triggers, which manifests itself as a sharp decrease in the charging current and its subsequent restoration, make sure that there are no obstacles to the ventilation of the charger housing.
