3. Why should we prefer rechargeable battery packs over non-rechargeable battery packs?

Non-rechargeable are the battery packs that can be used only once, and they are disposed of after usage.

They are not manufactured to be recharged, and then they are disposed of after discharging.

These types of batteries include silver oxide, zinc-air, carbon-zinc and alkaline batteries

Simultaneously, rechargeable battery packs can be used again and again, depending on their charge cycles.

The reusable battery packs have dedicated chargers for the charging of battery packs.

TLH offers Lithium-based rechargeable battery packs.

Rechargeable battery packs have the substantial upper hand on non-rechargeable battery packs.

The rechargeable battery packs offer an uninterrupted supply of voltage and current to your device; on the other hand, non-rechargeable battery packs offer supply only once.

The rechargeable battery packs are economical for long term usage; on the other hand, we need a lot of non-rechargeable battery packs for long term usage.

Rechargeable battery packs can be equipped with a battery management system to offer multi-level protections to your battery pack.

On the other hand, non-rechargeable battery packs aren’t equipped with the battery management system, or their installation will make them quite expensive.

Rechargeable battery packs have diverse applications as compare to non-rechargeable battery packs, and they can be installed in vehicles, medical equipment, military equipment and etc.

Non-rechargeable battery packs have to confine usage to tiny applications.

Non-rechargeable battery packs aren’t environmentally friendly, and they are more frequent to disposal because of their least life span.

On the other hand, rechargeable battery packs have many charge cycles, making them last for a more extended period.

Comparison of Rechargeable battery packs with single use battery packs

Figure 3 Comparison of Rechargeable battery packs with single use battery packs

Technology has evolved dramatically in rechargeable battery packs, but non-rechargeable battery packs haven’t seen any remarkable increase in development due to their limited time of life.

You can save a lot on logistics cost by adopting rechargeable battery packs, as they tend to last for a longer period so that you can cut down the logistics cost.

Lastly, suppose you are a B2C business.

In that case, you should know that the end customer doesn’t like to have a continuous change of batteries in their devices, so you should prefer rechargeable battery packs to enhance the end user experience.

For comparison of rechargeable battery packs with single use battery packs, please visit the following video.

4. What are the specifications and features of rechargeable battery packs?

Rechargeable battery packs are the core of your devices and systems as they provide uninterrupted supply.

Applications of rechargeable battery packs

Figure 4 Applications of rechargeable battery packs

6. How can we use rechargeable batteries of different capacities together?

Yes, you can use the batteries of different capacity together, but you should not mix the batteries of different chemical compositions.

This may lead to cells disruptions or leakage.

Batteries of different compositions have distinct properties of charge and discharge, which may lead to underperformance.

If you are using batteries of the same compositions, then you can use a combination of different ratings to set the ratings and capacity of rechargeable battery packs.

You can use two connections for it.

You can either use a parallel combination or use series connections to mold the battery packs’ capacity and output.

Parallel combinations of battery packs

Figure 5 Parallel combinations of battery packs

Series combination of battery packs

Figure 6 Series combination of battery packs

You can also use a joint combination of parallel and series together.

In series combination, positive terminals of a battery are connected to the next battery’s negative terminal; this formation is followed for the rest of the cells.

We can increase the overall voltage output of the battery packs from this combination because the total output is the sum of every individual battery pack.

In the parallel combination of battery packs, all batteries’ positive terminals are connected, and the negative terminals are connected.

Under this combination, the output current can be increased.

The output current is equal to the sum of the current of every individual battery pack.

The last combination is the parallel-series combination.

Under this combination, we can use both series and parallel combination together.

From this, we can get customized current and voltage output for our device and system,

While connecting batteries to any combination, you should make sure that there isn’t any short circuit between battery packs.

You can check this by DMM connectivity option, which is essential because it can lead to fire hazard and cell disruption.

7. How can we determine the rechargeable battery capacity?

You can determine the capacity of battery packs from its nameplate.

You can also consult the user manual of the battery pack.

In case both of these options are not available, you can use DMM to identify the battery pack rating.

You can quickly get a DMM from the market, turn the DMM selection switch to DC voltage supply, and connect the COMM terminal of DMM with the negative terminal and other terminals of DMM with the positive terminal.

By doing so, DMM will give you the exact output voltage of your battery packs.

You can connect DMM in series to the battery pack to determine the load current, and you can also use an Analog and digital ammeter for it.

You can then use the formula of P=VI to calculate the power capacity of the battery packs.

If you can’t use this method, you should look for the battery manufacturer number on your battery and battery packaging.

You can give this number to your battery manufacturer, and he/she will let you know about its battery capacity.

The American National Standards Institute (ANSI) procedure is as follows: Step 1 discharge new cells at 0.2 C to 1 volt. Step

2 Charge cells at 0.1 C for 16 hours. Step 3 rest cells for 1 hour. Step 4 discharge cells at 0.2 C to 1 volt. Battery capacity is determined by the hours of service to 1-volt times the discharge rate (mA x hours = mAh)

8. What are the protections placed in TLH’s Rechargeable battery packs?

We greatly emphasize user’s safety; hence our technical staff has taken special consideration for the battery protection.

We offer a Battery management system in our battery packs.

Along with BMS, we offer a cell balancing system in our rechargeable battery packs.

On the off chance that your cells aren’t balanced, it could influence your battery execution, subsequently adjusting the circuit is expected to control the battery on the occasion of unevenness.

Using an imbalanced battery will provoke under execution of the battery because the battery will not have the alternative to charge and delivery to its most extraordinary cutoff; like this, it will lessen the constraint of the battery cells.

Balancing the circuit is critical because it charges and deliveries the cells’ aggregate to their most extraordinary worth; this will grow the strength and decrease the chances of deficiency for your battery and device.

In the event that the cells have distinctive voltage levels across the cells, it could bring about ill-advised force appropriation from the phones to your gadget.

A balancing circuit is essential for your battery packs because it enables proper charging and discharging cycles.

Simultaneously, we offer protection against short circuit, over-voltage, overcharging and discharging.

We have placed relays of safe voltage level, and these relays trip the system if the voltage level exceeds the safe voltage level.

Protections in TLH rechargeable Battery packs

Figure 7 Protections in TLH rechargeable Battery packs

We equip our batteries with a battery management system, and this enables multi-level protection to your battery packs.

BMS restricts the excess flow of voltage and enables smooth flow of voltage to your systems and devices.

Our BMS is equipped with an advanced level of communication; hence it makes response time quick.

In case there is a fault, then BMS will trip the whole system to avoid any damage to the battery or the device.

Additionally, it will represent the error or fault on the HMI, and you can check the fault diagnosis from the user manual.

TLH also offer customized battery protections for your rechargeable battery packs.

You need to explain the battery applications to our technical staff, and we will suggest to you all the possible safeties related to it.

9. What are the reasons for the early discharge of Rechargeable battery packs?

There can be many reasons for the early discharge of rechargeable battery packs.

One of the main reasons for it is the imbalance of cells with the battery packs, disrupting the battery packs discharge and charge cycles.

Another reason for the early discharge is the exposure of battery packs to extreme temperatures.

Simultaneously, any abuse of rechargeable battery packs will also damage discharge cycles.

If you have store the battery packs for a more extended period, it could also lead to early discharge of battery packs.

In case you are ignoring the faults of battery packs, it could lead to disruption in battery cells hence disturbing the discharge cycles of rechargeable battery packs.

You can also experience early discharge if you aren’t charging from prescribed lists of manufacturer chargers.

10. What is the working phenomenon for Rechargeable battery packs?

Rechargeable battery packs have the same working phenomena that non-rechargeable batteries have.

It includes the chemical reactions on the negative and positive electrode of battery cells.

One electrode is having oxidation, while the other electrodes have a reduction.

These reactions enable the movement of positive ions to negative electrodes inside the battery.

This movement of ions inside the battery will result in current flow.

Rechargeable batteries have one difference from disposable batteries, and this happens when you use external power to charge the battery cells.
