Standard discharge current is related with nominal/rated battery capacity (for example 2500mAh), and cycle count. If the battery is discharged with a higher current, the real available capacity will be smaller (it may be much smaller). Discharging the battery with a lower current will extend the real available capacity a little bit.

While the self-discharge rate of NiMH batteries is high, there is a variation of called low-discharge NiMH. The discharge rate is as low as 0.25-0.50% per month but is used primarily in small rechargeable batteries. The popular line of Eneloop rechargeable batteries from Panasonic is perhaps the most widely used example of low-discharge NiMH.

However, it is more common to specify the charging/discharging rate by determining the amount of time it takes to fully discharge the battery. In this case, the discharge rate is given by the battery capacity (in Ah) divided by the number of hours it takes to charge/discharge the battery. For example, a battery capacity of 500 Ah that is ...

You read the battery datasheet. Either it will tell you the max discharge current, or it will tell you the capacity at a particular discharge rate, probably in the form C/20 where C means the capacity. You know the current you need : 4.61A. If the battery data lists a continuous discharge current of 5A or more, you are good.
"Increased battery discharge while stationary" indicates low battery voltage. This could be caused by an old or weak battery or one that is not charged enough. This could be caused by a problem in the charging system or by leaving the car with a low charge for an extended period.
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 ...
This is what we refer to as solar battery over-discharge. It''s when a battery''s charge is allowed to run too low or completely drain, often a result of using more energy than the solar panel is producing, leaving you with an empty battery and a power deficit. Causes of Solar Battery Over-Discharge Charge Controller Issues
$begingroup$ I think if you wanted to use a discharge rate that was lower than a battery''s self-discharge rate then the actual capacity would be lower than expected. As an extreme example, if you used the C value of a AA alkaline battery and expected to discharge it over 50 years you would be sorely disappointed. $endgroup$ –
(1) Constant current discharge. When the constant current discharge, the current value is set, and then the current value is reached by adjusting the CNC constant current source, so as to realize the constant …
Check the battery''s state of charge regularly using a hydrometer or multimeter. If the battery is not going to be used for an extended period, it should be fully charged before storage. Determining Battery Health. To determine the health of your deep cycle battery, you can use a multimeter to measure the battery voltage and the discharge current.
In order to protect the battery cell, it is not recommended to charge the lithium battery with a high current. If the battery is charged with a low current and a large current, it will heat up quickly and damage the battery. If you want to prolong the life, you can charge it at 0.3C.

Regardless of the type of charger you choose, you need to be sure that you don''t overcharge your battery. Providing your battery with too much charge can be just as harmful as providing it with too little. When you overcharge a battery, the excessive current heats the battery and cooks the components inside.

The answer depends on several factors, including the depth of discharge (how much of the battery''s capacity is used before recharging) and the operating conditions. Generally, limiting the depth of discharge to 80% or less can significantly extend the battery''s life. For example, a well-maintained lithium-ion battery might achieve:
