Why Esan Battery?
It should be checked by the nearest battery service. As a result of the service technical examination, the battery failure is detected and it is determined whether the malfunction is caused by the production or the user. Batteries with manufacturing faults covered by the warranty are replaced with a new one. If the fault is determined to be caused by the user, the battery is not covered by the warranty.
• Broken, Cracked, Damaged • Discharge
• Overcharging (due to connector failure)
• Sulfated (due to long waiting time)
When the battery usage conditions and manufacturer's instructions are followed, maximum efficiency and life are obtained from the product.
Battery life will be extended when the following conditions are taken into account;
- Selection of batteries with suitable capacity for the vehicle,
- No additional electrical loads are attached to the vehicle after it leaves the factory,
- Consumers are not used for a long time while the engine is not running,
- The vehicle is not left parked for a long time,
- Avoiding short distance and frequent use of the vehicle,
- Periodic control or maintenance of batteries,
- Periodic control of vehicle charging system voltages and verification of their compliance
- In case of parked leakage currents are not above the factory values,
- Over-discharged batteries should be charged outside the vehicle and in accordance with the battery charging instructions.
Batteries end their life depending on the frequency and conditions of use. Under normal conditions of use; In addition to meeting the energy needs of vehicles with high current starting (several hundred amps), air conditioners, lamps, signals, panel display, radio-cd player and so on. They also meet the energy needs of all electrical devices. At the same time, in addition to discharges, the batteries wear out during charging with the operation of the vehicle and end their life.
It should be checked by having it checked by the nearest battery service. If the battery has reached the end of its life, the battery should be replaced, if the need for discharge or maintenance is detected, the necessary action should be taken in accordance with the battery charging and instructions.
How to Boost the Battery?
Take the necessary precautions by following the safety rules before the battery connections.
- Turn off the engine and all electrical loads (ignition, lamps, radio, etc.).
- Make sure that the vehicle-battery voltage system (12V and/or 24V) to be connected from the battery (jump-start) to the battery is the same.
- Make sure that the cables do not come into contact with the moving and/or hot spots (Exhaust, Radiator, Propeller, etc.) in the vehicles.
- First, connect the red end of the jumper cable to the (+) terminal of the discharged battery and the other end to the (+) terminal of the full battery.
- Then connect the black end of the jumper cable to the (-) terminal of the full battery, and the other end to any metal part of the body of the vehicle with the discharged battery.
- First start the vehicle with the full battery, then start the vehicle with the empty battery.
- After the vehicles have started, disconnect the wires from the (-) negative terminals and then the (+) positive terminals in order, starting from the vehicle with the empty battery.
• Batteries; Depending on the charge level and electrolyte densities, they may freeze. The freezing temperature of fully charged starter batteries goes down to about -69°C and the freezing temperatures vary depending on the density of the electrolyte.
• As the density decreases (the densities due to discharges in batteries may decrease to 1,280g/cm3-1,100g/cm3 and below), the freezing temperature also increases. For example;
- Fully charged, density is 1,280g/cm3, freezing temperature is -69°C.
- Discharge, density is 1.150g/cm3, freezing temperature is -15°C.
• Under normal conditions, charged accumulators do not freeze. However, depending on the discharge level, there is a possibility of freezing even at 0°C to -15°C, care should be taken to keep the batteries charged in cold seasons and climates.
Weather conditions affect the batteries significantly during storage and working on the vehicle.
- Warehouse and Stockpiling;
Batteries should be stored in cool, dry, closed areas that will be least affected by physical conditions such as dust, sun, temperature, humidity, etc. Temperature, dust, humidity and precipitation increase self-discharges.
Temperature increases self-discharges, with a general approximation that every 10°C increase in storage temperature doubles spontaneous losses. For this reason, batteries that stand at 20°C on average can wait 2 times longer than those stored at 30°C. It minimizes storage capacity losses in cooler environments and is healthier.
- During operation (on Vehicle):
Temperature values directly affect the working, life and starting performance of the batteries. In hot environments, the starting performance increases due to the chemical reaction rates of the batteries, and at the same time, the mechanical starting energy needs of the vehicles decrease, although premature aging occurs in the batteries due to corrosion. In hot environments and climates, the batteries will be disabled earlier and their life will be reduced.
Despite the decrease in the starting ability of the batteries in cold weather and climates, the starting energy needs of the vehicle engine increase. Because of this dilemma, batteries with higher starting power are required for cold weather and climates.
There is a risk of freezing the battery electrolytes in the cold. While a fully charged battery freezes at -69°C, a discharged battery can freeze even at 0°C or -5°C depending on the discharge level. For this reason, it is very important to keep the batteries charged in cold weather.
Illuminates due to battery and vehicle charging system problems. In general, the warning lamp may turn on due to the problems listed below;
- The voltage cannot rise due to the exhaustion of the battery,
- Failure of the vehicle charger,
- Deterioration of the vehicle connector,
- Looseness in battery connection cables,
- Break in electrical circuits.

Before charging and connecting the battery, take the necessary precautions by following the safety rules.
Before charging, the charge current and times are determined from the instructions, depending on the determination of the charge level of the batteries and the current charge rate.
- Determine the charge level of the battery.
- Make sure that the electrolyte temperature is >15°C before charging.
- Determine the charging requirement by measuring the open circuit voltage (measuring the cell densities in the openable ones) in the batteries. If the open circuit voltage is < 12.40V, the batteries waiting in the warehouse are charged.
- Check the charger, if it is on, turn it off.
- Connect the battery to the charger with the positive cable to the positive terminal and the negative cable to the negative terminal. Make sure that the polarity connections are made in the correct polarity.
- Start charging by selecting the current and voltage values suitable for the battery in the charger.*
In unused batteries, charging is terminated when the electrolyte density reaches 1,280±0.010 g/cm3.
- During charging, the electrolyte temperature should not exceed 45°C, when it passes, it is cooled or expected to cool. Excessive temperature will cause overcharging and damage the battery.
- Charging is terminated when the specified conditions are reached. The connection cables are first disconnected from the negative and then the positive connections.
***They are charged with the current and times given in the charging tables determined depending on the charge levels detected in the waiting batteries or discharged batteries from the customer. In cases where the desired density is not reached in the used batteries, if the measured and corrected density does not change in the last two hours of charging, charging is terminated. In the batteries whose density cannot be measured, charging is applied according to the voltage values.
In cases where the rules and laws are not followed during the production, use and transportation of batteries, they can be harmful to the environment.
- Sulfuric acid solution and
- They consist of polypropylene box-lids.
End-of-life batteries are hazardous hazardous wastes for the environment. When the batteries are collected, stored and transported to recycling facilities in accordance with the rules, lead and plastic parts are 100% recovered by recycling. Sulfuric acid can also be recovered but is usually neutralized.
They are Start & Stop Vehicle Batteries developed to reduce fuel consumption and reduce carbon emission rates.
There are two types of Start & Stop Batteries, EFB and AGM. Compared to standard batteries, these batteries have a high rate of charge in a very short time, as well as high cranking and cycling capacities.
