Min & Typ Battery Meaning & Comparison


On rechargeable batteries, the terms “min” and “typ” are widely used.

Because battery capacity is slightly inaccurate, manufacturers cannot specify the precise power and instead write two numbers, one for the minimum (min) capacity and the other for the nominal capacity (typ).

Indicators for the min & typ battery capacity

Typ BatteryLet’s get started studying battery indications if you’re interested.

The terms “minimum” and “normal” in the context of a mobile phone refer to the charge at 95 per cent and 100 per cent, respectively.

According to the BMS/charging-safety, when a mobile phone is charged, according to the BMS/charging-safety, it first reaches a minimal, than usual, which takes a long time.

The nominal capacity is indicated by the capacity written on the smartphone batteries.

If a phone’s battery capacity is 4000mAh, for example, this is the standard capacity.

No manufacturer, however, can confidently state the capacity of their batteries due to the minor inaccuracy involved with battery capacities.

As a result, manufacturers set a minimum capacity, such as 3900mAh, to ensure that the battery capacity is not below that level.

Voltage minimum

The min voltage value is the safest voltage level for discharging a battery.

Remember that if the voltage falls below the prescribed minimum voltage, the battery may be destroyed.

The battery may be damaged if the voltage is lower than the minimum value.

Typical/rated voltage

The rated voltage is the voltage that a battery or gadget requires to work correctly, as determined by the manufacturer.

For example, you may have observed the words “Input: 100–250 VAC” printed on the label of a mobile phone charger.

This is the voltage at which the phone charger is intended to function.

Voltage maximum

This is the maximum voltage a battery may be charged to.

The difference between rated and actual capacity. What is the reason for this?

The voltage of lithium-ion batteries, which are utilised in products like power banks, is 3.7V.

On the other hand, USB output ports offer 5V, as stated on the package or on the power bank itself.

Voltage variations result in capacity changes; for example, switching a 15000mAh power bank to 5V reduces its capacity to 11100mAh; and vice versa.

Furthermore, voltage conversion generates heat and wastes energy, reducing the battery’s capacity.

The effectiveness of conversion varies depending on the product and brand.

Certain brands make mention of a product’s conversion efficiency, while others do not.

Depending on the product, the proportion could be anything from 2% and 10%.

The formula for calculating actual capacity is as follows:

Actual capacity = 3.7V x Advertised capacity x Efficiency (in decimal) / 5V Actual capacity = 3.7V x Advertised capacity x Efficiency (in decimal)

See the article Why is there a variation between actual and rated battery capacity? for additional information.

Why don’t manufacturers disclose the actual output of a power bank?

Because of the market’s intense competition, producers attempt to attract customers by labelling their items with larger capacities.

The second reason is that they do not offer statistics on conversion efficiency rates and other metrics, making it easier to compete with companies with higher conversion rates.
