LOADING A 2.3 OR 4 STAGE CHARGER FOR THE CAR BATTERY?

Although we, as mentioned earlier, can quickly recharge via a (limited) voltage source has practiced with a specific resistance shown that this not an ideal way of recharge. Also, this method is also often impractical because you have to keep an eye on when charging to stop.

This way, while not designed for continuous charging (trickle charge) and there is the danger of overcharging and further gasification of the electrolyte. For optimal charging of the best car battery has been found that this is best in a number of steps can be charged.

These steps are referred to:

1. Bulk: charging a constant charging current. Displays the battery on the correct placed voltage (about 14.4 volts) and then proceed to the absorption phase. In this step, the battery receives the majority of cargo. The battery after this stage loaded 75 to 90%.

2. Absorption: weight by a constant voltage charge. The charging current increasingly decreases. The bulk to absorption and together provide for factual fully charging the battery (100%). The more the battery was discharged, to take longer these phases together.

3. Float or trickle (drip): also by a constant voltage charge. Here start the maintenance mode of the battery (often this position is the ‘TKO’ called). The battery voltage is reduced, and the battery goes in storage mode. The lower storage voltage reduces corrosion of the positive plates.

4. Storage: In this then the load remains continuously active. The charging voltage is at or slightly above the level of the no-load tension between the battery terminals. Only 4-stage chargers know this full maintenance schedule. These chargers are ideal for continuous maintenance of batteries of campers and engines their winter storage.

A 4-stage battery charger ensures that all phases are completed accurately with a loaded as optimally as possible and conditioned battery as a result. If a battery is not frequently deeply discharged, a 2-stage charging curve can used (bulk followed by float). During the first phase the battery charged with a limited current (the bulk phase). Once a preset voltage is reached, the battery is kept at that tension (the float period). This charging method is used for starter batteries in vehicles, and uninterrupted power supplies. Discharging of the battery and charging at the same time with such charging circuits possible.

A disadvantage of the 2-stage is that the battery charger when switching from bulk to float is not fully charged, but only 75 to 90%. In float mode, the battery very slowly recharged. Such a loader is therefore not suitable for mobile applications where a maximum capacity of the battery should be used.

It may be clear that loading rapidly combined with a continuous, optimum performance only be achieved with a 4-stage charger. This charger plugs up, sets it up and arrange everything else yourself. Very comfortable: no tampering timers, always coupling to the battery is not a problem. Does your battery longer and better it. The Chargers Mobile energy.No example sells, load all 4 phases to make the battery fully pampered so you years of pleasure has.

Charger choice: the optimal charging current

The charging current during the first period (bulk) of the load should preferably be 0.2 not exceed C. Where C is the capacity of your battery in ampere-hours (Ah). For example, up to 20 amps for a 100 Ah battery.

What happens when too small charging current?

But when loaded long enough, you get with every charging current to the battery or full, as is thought. But unfortunately, a battery can be damaged to be at a small charging current. Brief explanation: it will by gravity released massive acid (while charging) remain at the bottom of the battery. As the charging current is large enough, a sufficient gassing in the battery will occur. hereby acid results in a good mixing in the battery, so that the specific gravity of the electrolyte top and bottom of the battery is substantially equal. This increases the service life of the battery significantly. Therefore, always take a charger with a charging current of at least 8% of the nominal capacity of the battery.

How long will it take before my battery is full again?

This depends on some factors: the capacity of the battery, the size of the charging current, discharge and quality of the battery and whether there are active consumers connected to the battery. In a discharged battery, the load time to be determined as follows:

Charging time = battery capacity divided by the load current + 4 hours. For example, a 200Ah battery is charged with 24 Ampere charging current. The load time when a discharged battery is approximately 200/24 + 4 = 12 hours. There are loads connected to the battery must by those withdrawn flow of the charging current to be subtracted. If consumers always are linked, we recommend a charger with a larger charging current to take.
