If you recharge a battery that is not completely flat often, the battery overcharges often. The reason this is not a huge problem is that you maybe get 100 maybe 200 cycles even when torturing a battery in this manner. …
To fully charge the battery, you need to eventually get it up to 4.2V. But if you just apply a 4.2V across it when it''s completely discharged, you''ll be putting 4.2V-2.75V=1.45V across a 130mOhm impedance. That means the charging current will be on the order of 10 amps, which is much higher than the battery is rated for.
If the continous discharge current is set at 35A, instead of 45A, will this provide a longer ride per full charge? ... Does a lithium ion battery need to be stored in it''s charger in order to preserve it''s life expectancy. ... "WHAT TO DO" to achive discharge to get battery back to 12.53 or can it even be discharged that would be better ...
Disposable batteries can only be used once before they need to be replaced. If you''re talking about charging a rechargeable battery, like the kind you find in laptops and cell phones, then you can usually recharge it after it''s been completely discharged.However, this isn''t always the case. Some batteries may not hold a charge as well after being fully discharged, so …

The battery''s …
The state of discharge on a battery that''s been under a load for most of the day would typically be between 25% and 30% full. Use a voltmeter with the battery detached from the system to read the voltage of the battery. This state of discharge will partly decide how long you should be charging deep cycle battery components. Refer to your ...
A lithium-ion battery provides 300-500 discharge/charge cycles. The battery prefers a partial rather than a full discharge. Frequent full discharges should be avoided when possible.
Let''s explore a few commonly observed discharge profiles: 4.1 Constant Current (CC) Discharge. During the initial phase of a lithium-ion battery''s discharge, it often follows a constant current (CC) profile. In this stage, the battery delivers a steady current while maintaining a relatively high voltage.
3 · An inverter converts DC (direct current) from a battery to AC (alternating current) to power devices. This process draws power from the battery. Over time, the repeated discharge and recharge cycles can lead to a decline in battery capacity. When an inverter operates constantly, it keeps the battery in a state of partial discharge.
There would be a 8.33% charge loss for every 1 value drop in voltage. So the SafeZone for a 48v battery discharge would be 42v, implying the battery is 50% charged. when connected to the multimeter, sometimes a 48v battery might give a higher reading. If you are getting 50v reading out of your 48v battery, there is no need to panic.
Eventually, the battery will completely discharge if it''s left uncharged. Jump to: ... a mechanic can easily diagnose this by performing a parasitic current draw test. 3. There''s a defective alternator ... In winter your car can need twice as much power to start. In summer, your battery''s vital liquids can evaporate, which can lead to ...
In theory all batteries would last longer if between 40ish and 80ish percent. Because those phones are programmed to have all the benefits of charging the battery to 80 and then just using the power cord for the rest of the night.
They self-discharge at a lower rate than other battery types, losing only 1 to 2 percent per month (as long as the weather conditions aren''t too extreme). They do not require periodic full ...
ANY battery does not just throw amperage or current; it will first discharge as much current as physically possible based on its chemistry and chemical reaction, and then …
A 12 volt battery with no load should read 12.7 volts. When Does a Deep Cycle Battery Need to Be Charged? Standard lead acid deep cycle batteries can withstand being discharged to 50% repeatedly and take minimal …
If you want a the battery to last a "long" time and no overheating, then the charging or discharging current must be kept at not more than 1/10 of the rated capacity. You also need to keep in mind that a battery is …
This is the amount of current that a battery can provide before it is considered fully discharged. The higher the discharge current, the more power the battery can provide. For example, a battery with a maximum discharge current of 10 amps can provide twice as much power as a battery with a maximum discharge current of 5 amps.
Battery continuous discharge current needs to be below or equal to the controllers'' max continuous current. The way you''ve said it, battery continuous discharge ≤ controller max continuous current. It should be the other way …
Batteries are literally a battery (3a) of electrochemical cells.. Older batteries used multiple cells connected passively to produce the desired voltage and capacity. Newer batteries - and all Li-Ion and Li-Po batteries use a controller which regulates internally the use of each cell.
The time it takes to discharge a sealed lead-acid battery can vary depending on the load and the battery''s capacity. It is important to monitor the battery''s voltage during the discharge process to ensure that it does not drop below the recommended threshold. The temperature of the battery can also affect the discharge time.
$begingroup$ It has 2 components, when initially turned ON, inrush current exists, which depends on ESR of your cap and dV/dT of turn ON. after that transient event, capacitor slowly charges. Charging time constant …
The need to perform this procedure will vary with individual use. In general, a Li-Ion battery should be calibrated a minimum of once every 3 months. A battery that is seldom discharged completely should be calibrated about once a month. and the following is from Battery University: How often does a battery need calibrating?

$begingroup$ @Dejvid_no1, sounds like you are presenting guess work instead of scientifical facts, or you are negligent in how you express yourself. First you say "no, [not] at all" — it''s never safe to fully discharge. Then you go on to state that problems happen "during charging" — which is a different activity.
You just need to connect each terminal and hit the "load" switch on the device. A good, charged battery should remain in the green (good) section. You can also check the charging system with this tool. But as long as the battery is somewhat good quality just charging it should be good enough. A slow charge is the best option for battery health.
Depth of Discharge measures the percentage of a battery''s capacity that has been depleted, with higher DOD values indicating more energy has been consumed. You can think of it like a fuel gauge for your battery, …
As has already been said, most modern LiPo battery packs have internal circuitry to prevent them from discharging to a point where the cell would be damaged. However, this achieves your goal. Just discharge them at about C/10 until they do not pass anymore current. So if they are a 5Ahr battery, discharge them at 500 mA until they go dead.
In the context of car batteries, they determine the battery''s ability to start an engine—essentially, how much power can be delivered to crank the engine successfully. Cranking Amps vs. Cold Cranking Amps. Cranking Amps (CA): The number of amps a battery can provide at 32°F (0°C) for 30 seconds while maintaining a voltage of at least 7.2 ...
To extend the battery''s useful life for as long as possible, you need to take care of your device properly. That means adopting good charging habits and taking care with battery storage. Here ...
One way to discharge a LiPo battery quickly and safely is to use a battery discharger or a charger with a discharge function. Another method is to use a power resistor to discharge the battery. You can also discharge the battery by using it until it is completely dead, but this method can be risky and should only be done under careful supervision.
