Chargers use different technologies and algorithms, differ in power and size, but have a general principle of operation – the batteries are charged because the voltage at the output of the charger is higher than the voltage at the battery terminals. The voltage difference causes the current to flow from the source (charger) to the load (battery). And it is very important to take into account all the characteristics of the battery in order to choose and successfully use the best deep cycle battery charger.

When do I need to charge the battery?

It is best to charge the battery immediately after it has run out. Therefore, never leave traction batteries in uncharged condition.

Rechargeable batteries never discharge more than 80% of their rated capacity. Discharging below this limit leads to deterioration of the active mass, as a result of which the effective capacity decreases.

Deep cycle battery

To charge a 12-volt battery, the charger must provide at least 14 volts. However, if the voltage exceeds 15 volts, then the battery will overheat, gas generation, evaporation of the electrolyte and deformation of the plates will begin in it.

How much time should I charge a battery?

There is no single answer to this question. The battery charging time depends on the charge coefficient, on the one hand, and on the type of charger, on the other hand.

Charge ratio

The battery is charged by supplying it with the energy of a higher level compared to the level of energy consumption. The charge ratio of a battery is the ratio between ampere-hours to a charged state and ampere-hours of consumed energy. Most batteries have a charge ratio of 1.2.

Example. The traction battery with a rated power of 1000 Ah has been discharged by 80% (800 Ah). With a charge coefficient (KZ) of 1.2, the battery should return 1.2 x 800 Ah-960 Ah.

Charger Type

There are various types of chargers on the market. In addition to a conventional or low-frequency charger, another common option is a high-frequency charger. A high-frequency charger costs a little more, but charges batteries faster and in a more economical way compared to

with a conventional charger. The battery lasts longer thanks to the use of smart charger technology. The high-frequency charger charges efficiently and prevents premature wear on both the battery and the charger.
