Use caution when removing and replacing the caps. To get a good sense if your battery is the cause of your issues, test the voltage using a multimeter. Put the black multimeter lead on the negative battery cable and the red lead on the positive cable. If the reading is Fully charge the battery and have a load test done to determine if it will hold a charge. Many mechanics and auto parts stores will test your battery for free.
The results of this test will tell you if you need a new battery or if you need to keep looking if your starting problems persist. From a faulty starter to a bad alternator, there are a range of possibilities of where the problem lies.
Armed with the information you give them, your mechanic will have a head start on diagnosing and fixing your vehicle.

As soon as the clutch pedal is pressed again, or the brake is released in the case of an automatic transmission, the engine starts again immediately. In addition to frequent engine starts, which the battery must supply for this process, it also supplies all of the electronic consumers even when the engine is switched off.
You could say that the car battery is the heart of the system for modern vehicles. The reason why the start-stop system does not function can be due to the interaction between both of these essential systems.
The top priority for any battery is to start the engine. However, if the battery only has a low charge, the Battery Management System BMS switches off the start-stop function to enable the engine to be started. A similar protective mechanism operates in the following cases:. The wrong battery technology has been installed, which can only provide a small number of charging cycles. The outside temperature is too high or too low. If the battery needs too much power to supply the fan, the start-stop function is switched off.
To help prevent a dead battery, you first have to know what causes one. So, put those jumper cables aside, and check out these seven things that could explain why your car battery keeps dying. If your car battery keeps draining, the first things to check are your lights. Many newer vehicles have headlights designed to turn off after a certain amount of time. Even while your car is off, your battery provides power to things like the clock, the radio, and the alarm system.
These things shouldn't have a major impact on your battery. What may drain a car battery when it's off are things such as interior lights, door lights, or even bad relays. While your engine runs, the alternator recharges the battery — which is why you typically don't have to worry about the battery dying while you're blasting the radio on your drive to work!
But when the engine is off, the alternator can't recharge the battery, allowing little electrical mishaps to drain your battery entirely.
The battery strain caused by these electrical whoopsies is known as a parasitic draw. You can help avoid parasitic draws by turning off every light and making sure your trunk, glove box, and doors are fully closed and latched before leaving the car. The positive and negative terminals connected to your battery can sometimes jostle loose over time.
These terminals may also become corroded. If your terminals become loose or corroded, you might have trouble starting the vehicle because your battery can't properly transmit its power!
Otherwise , it will be trouble to have a single string and re-disassemble. This situation is rare as the battery pack fires , but the consequences are severe. The cause is also due to external or internal long-term short circuit. The external short circuit is equivalent to an immediate super-large current discharge , which exceeds the limit of the cell protection board , and the internally generated gas is instantaneously ejected , which is very dangerous.
An internal short circuit and a poor sealing effect of the diaphragm may also explode. For the prevention of external short circuit , the protection board can be used to avoid. The protection board has short-circuited and over-current protection function to eliminate this risk , but the internal short circuit of the lithium polymer battery must be reduced by using the qualified manufacturer qualified battery.
In conclusion , battery selection , pack process , charger , protection board problems , line connection , and improper use can cause the Li Pol Battery Pack to malfunction , try to avoid these hidden dangers and ensure the safe use of the battery pack. Normally batteries are composed of several identical secondary cells in parallel addition to increase the discharge current capability.
Please note the battery we quote is a standard battery with protection circuit and wires 50mm. If you want High-rate discharge , please contact us. We also have stock some 3C-5C lithium polymer batteries. If the temperature is too low , the capacity will be significantly reduced ; If the temperature is too high , the battery is prone to internal short circuit ;.
In addition , we can make encryption that are suitable for low temperature or high temperature , but need to re-create and use a special electrolyte. In normal conditions , the lead time of samples will be days. For largo order , the lead time will depends on the quantity. Different battery model with a different MOQ , more details please send a email to us. After analysis the loss capacity of lithium polymer battery , we got the main reason is overcharge that charging voltage is over the prescriptive voltage 4.
In this process of overcharge will result in loss capacity of lithium polymer battery. The main points are as follow. Lithium ion will be easy deposited on the cathode and stop lithium ion implanted. The efficiency of discharge and capacity of lithium polymer battery will be lost.
