Regular maintenance is required to extend the life of the starter car battery. One of the mandatory points is to maintain a normal charge level. This is especially true for winter operation, because due to the large number of powerful consumers and severe frosts, the standard car voltage relay is not able to fully charge the battery.
Content
Device Overview
The charger is made in a small plastic case (185x130x90 mm). The low power of the device led to its low weight.
On the front panel are located:
- Pointer ammeter to control the charge current;
- LED indicator of an operating mode;
- "Cycle - Automatic" mode switch.
A power cord and wires with terminals for connecting the battery come out from the back of the device.
Technical characteristics of the device Cedar Auto 4a
This charger provides a charge current of up to 4 A. This is enough to maintain the capacity of incompletely discharged batteries. Other specifications:
| Characteristic | Value |
|---|---|
| Voltage | 220 volt |
| Maximum charge current | 4 amperes |
| Power consumption | 85 watt |
| Battery Voltage Rating | 12 volt |
| Suitable for charging batteries | WET only |
| Rechargeable battery capacity | 30 to 75 A / h |
| Dimensions | 185x130x90 mm |
WET batteries are standard liquid acid electrolyte lead-acid batteries. Do not attempt to charge the AGM, EFB, or GEL battery with this memory.
The charger kit includes instructions for the rules of use, which detail the procedure for working and possible malfunctions with the procedure for their elimination.
Features of the device and for which battery is suitable
The automatic charger is designed to charge lead-acid batteries with a capacity of 40 to 75 Ah.
Important! The larger the battery capacity, the longer it will take to charge it. Moreover, many manufacturers recommend setting the charge current equal to 1/10 of its capacity. Thus, this device is not recommended for regular charging of powerful batteries with a high degree of discharge.
The device has built-in protection against incorrect switching - polarity reversal. The output voltage and charge current are absent in such cases:
- Incorrectly connected battery;
- High degree of discharge (voltage at the battery terminals less than 10 V);
- Lack of battery.
Cedar Auto 4a has two operating modes - “automatic” and “cycle”. Each of the operating modes uses its own charging algorithm.
The operation indicator light has the following modes:
- Off - Automatic mode;
- Blinking - in the “Automatic” mode the charge is over;
- Continuous light - “Cycle” mode is on.
Machine
This mode is the main one and is designed to charge batteries without user intervention. The logic of operation is such that when a discharged battery is connected, the device starts to produce maximum current, which decreases as the charging process proceeds. When the battery voltage reaches 13.2 V, the charge automatically stops.
Important! The initial current depends on the degree of discharge of the battery, but does not exceed 4A in the most extreme case.
Cycle
The mode is designed to restore batteries with signs of sulfation. In the cyclic mode, the charge alternates with a short-time discharge with a small current, which contributes to the dissolution of large sulfate crystals in the active mass of the plates.
How to charge the battery using Cedar Auto 4a
Using an automatic device simplifies battery maintenance as much as possible and allows you to make it regularly without significant time investment.
Procedure:
- Connect the battery to the output terminals of the device;
- Connect the device to the mains;
- By pressing the button on the front panel, select the desired operating mode.
Important! In the case of desulfation (“Cycle” mode), a load must be connected in parallel with the output terminals - a 12 V 6 W car lamp through which the battery will be discharged.
Using a more powerful lamp will increase the discharge current, resulting in longer charging time. A light load, on the contrary, will not give the desired effect.
In the process of charging, it is necessary to control the density of the electrolyte. The lack of density growth with an undercharged battery suggests that desulfation is necessary.

On occasion, I bought a memory Cedar Auto 4A. Despite the fact that this device does not shine with its characteristics, its price has bribed. I try to take care of the car, and since winter is coming, I think that the purchase will not be in vain.

Friendship gave gifts for the anniversary. At the very hands did not reach buy. From the pros I want to note:
- Full automation;
- Ease;
- Confidence that there is nothing to break.
There are also disadvantages:
- Lack of power switch;
- Low charging current.

Auto began to turn bad - sat battery. He is limited in finances, so he bought an inexpensive memory Cedar auto 4a. Works fine. For my purposes, it’s enough, especially since no action is required other than the correct connection.
