Verifone POS Terminal Battery Replacement Guide: Models, Compatibility and Buying Tips

Verifone POS Terminal Battery Replacement Guide: Models, Compatibility and Buying Tips

Verifone POS terminals are widely used in retail stores, restaurants, delivery services, mobile payment scenarios and field sales. For many businesses, the terminal itself may still work well after years of use, but the battery starts to lose runtime, charge slowly, or shut down unexpectedly during transactions.

When this happens, replacing the battery is usually more practical than replacing the whole POS terminal.

However, choosing a Verifone POS terminal battery is not as simple as picking a battery with similar size. Different Verifone models may use different voltage, capacity, connector, pin layout, battery housing and protection design. A battery that looks similar may still fail to charge or power on the terminal if the connector or polarity is different.

This guide explains how to choose a suitable Verifone replacement battery, what information buyers should check before ordering, and how Cowon supports OEM and custom POS terminal battery solutions.

Why Verifone POS Batteries Need Replacement

Most Verifone POS terminal batteries are rechargeable lithium-ion battery packs. Like all rechargeable batteries, their capacity gradually decreases after repeated charge and discharge cycles.

A new battery may support several hours of mobile payment use. After long-term use, the runtime can become much shorter. In some cases, the terminal may turn off during printing, NFC payment, card reading or network connection because the battery can no longer support stable current output.

Common signs that a Verifone POS battery needs replacement include:

• The POS terminal shuts down even when the screen still shows battery power.

• The battery drains much faster than before.

• The terminal only works when connected to a charger.

• The battery cannot be fully charged.

• The battery becomes swollen or deformed.

• The terminal shows a battery error or cannot detect the battery.

• The device restarts during printing or payment processing.

For merchants, these problems are not only technical issues. They can interrupt payment collection, delay checkout, and create a poor customer experience. For POS service companies and repair suppliers, keeping reliable replacement batteries in stock can also reduce after-sales pressure and repair turnaround time.

Common Verifone POS Terminal Models That May Use Replacement Batteries

Verifone has released many POS terminal models for different payment applications. Some are handheld mobile terminals, while others are countertop or semi-mobile payment devices.

Common Verifone models related to replacement battery demand include:

• Verifone VX670

• Verifone VX675

• Verifone VX680

• Verifone VX685

• Verifone VX690

• Verifone V200t

• Verifone V240m

• Verifone V400m

• Verifone C680

• Verifone X970

• Verifone X990

• Verifone S600A

• Verifone Topaz series

These models are not universal. Even if two devices belong to the same Verifone family, the battery may still be different. For example, one model may use a 3.7V single-cell lithium battery pack, while another may use a 7.2V or 7.4V two-cell pack. Some batteries use wire connectors, while others use contact pins or a plastic housing design.

That is why buyers should never confirm compatibility only by the words “Verifone battery” or “POS battery”. The exact device model and original battery information are much more important.

OEM Battery vs Replacement Battery

When sourcing Verifone POS terminal batteries, buyers usually have three options: original battery, compatible replacement battery, or customized battery pack.

Original Verifone Battery

Original batteries are usually supplied through official channels or authorized service providers. They are normally the safest choice for strict enterprise maintenance systems, especially when the buyer needs original traceability, official warranty support or internal compliance records.

The downside is that original batteries may have higher cost, longer lead time, or limited availability, especially for older POS terminal models.

Compatible Replacement Battery

A compatible replacement battery is designed to match the original battery’s key specifications, such as voltage, capacity, connector, size and protection function.

For many repair companies, distributors and POS equipment service providers, a good-quality compatible battery is a practical choice. It can help reduce cost, shorten lead time and keep older terminals in service.

The key is to choose a supplier that understands battery pack design and can verify compatibility before production.

Customized POS Battery Pack

In some cases, buyers cannot find a ready-made battery that matches the original one. This is common when:

• The original battery has been discontinued.

• The buyer needs a different connector.

• The old battery label is unclear.

• The customer wants private label packaging.

• The buyer needs bulk supply for repair or refurbishment.

• The terminal is used in a special environment.

• The battery requires a specific PCM, NTC or wire sequence.

In these cases, a customized replacement battery pack may be a better solution.

Cowon can support custom POS terminal battery packs based on the original sample, battery label, device model, connector photo and required specifications.

Key Specifications to Check Before Buying a Verifone Battery

Before ordering a Verifone POS terminal replacement battery, buyers should confirm the following information.

1. Terminal Model

The first thing to check is the exact Verifone terminal model.

Do not only write “Verifone POS machine”. A supplier needs to know whether it is VX680, VX690, V240m, V400m, X990 or another model.

The model number is usually printed on the back label of the device, inside the battery compartment, or on the original product documentation.

2. Original Battery Part Number

The original battery part number is one of the most useful references for matching.

Examples of Verifone battery part numbers may include codes such as BPK series numbers or other printed model codes on the battery label. For some models, the replacement battery may be listed by both the terminal model and the original battery code.

When contacting a supplier, it is best to send a clear photo of the original battery label. This helps avoid mistakes caused by similar product names.

3. Voltage

Voltage must match the original battery.

This is one of the most important rules.

A 3.7V battery cannot be replaced by a 7.4V battery. A 7.4V pack cannot be replaced by a 3.7V pack. Even if the connector looks similar, using the wrong voltage can cause the terminal to fail, shut down, refuse charging, or become damaged.

Common Verifone POS battery voltages may include 3.6V, 3.7V, 7.2V and 7.4V, depending on the model and battery structure.

Always check the original battery label before ordering.

4. Capacity

Capacity is usually marked in mAh. For POS terminal batteries, common capacities may range from around 1800mAh to 2600mAh, 3350mAh or higher, depending on the battery size and terminal model.

A higher capacity may provide longer runtime, but it does not always mean better compatibility. If the battery is physically larger or uses a different cell structure, it may not fit into the battery compartment.

For business users, the right capacity should match the real working scenario. A mobile restaurant, delivery service or outdoor payment team may need longer runtime. A countertop terminal that stays near a charger may not need the highest capacity.

5. Battery Size and Housing

Many Verifone batteries are designed to fit a specific battery compartment. The length, width, thickness, latch position and housing shape must be correct.

If the battery is too thick, the battery cover may not close. If the housing shape is different, the battery may become loose inside the terminal. If the contact position is not aligned, the device may not power on.

For bulk orders, it is better to confirm dimensions by sample or technical drawing before mass production.

6. Connector and Pin Layout

Connector compatibility is one of the most common problems in replacement POS batteries.

Some Verifone batteries use wire connectors. Some use contact terminals. Some may have 2-pin, 3-pin or 4-pin layouts. Even when the connector looks similar, the polarity or signal line may be different.

A mismatched connector can cause:

• No power output

• Charging failure

• Battery not detected

• Intermittent shutdown

• Terminal restart during use

Before placing an order, buyers should provide clear photos of the original connector from the front, side and wire side. If possible, also provide the wire color sequence.

7. NTC or Temperature Sensor

Some POS terminal batteries include an NTC temperature sensor. This allows the terminal or charger to monitor battery temperature during charging and operation.

If the original battery has an NTC function but the replacement battery does not, the terminal may refuse to charge or show an error.

For professional replacement battery production, the supplier should check whether NTC is required and whether the resistance value matches the original design.

8. Protection Circuit

A POS battery pack normally needs a protection circuit to prevent overcharge, over-discharge, over-current and short circuit.

A reliable PCM or protection board is especially important for lithium-ion batteries used in commercial devices. Poor protection design may lead to short cycle life, unstable output or safety risk.

For replacement batteries, the protection circuit should be selected according to the cell type, voltage, working current and charging method of the terminal.

9. Certification and Transport Documents

For international buyers, certifications and transport documents are also important.

Depending on the order quantity and destination, buyers may need documents such as:

• UN38.3

• MSDS

• IEC62133

• CE

• RoHS

• Battery transportation report

• Air or sea shipping documents

For distributors and importers, these documents can help with customs clearance, transportation and customer compliance requirements.

How to Confirm Compatibility Before Ordering

A good supplier should not ask buyers to confirm compatibility only by model name. For Verifone POS terminal battery replacement, the safest way is to check several pieces of information together.

Before ordering, buyers can prepare:

• Photos of the original battery label

• Photos of the terminal model label

• Photos of the battery compartment

• Photos of the connector or contact pins

• Battery voltage and capacity

• Original battery part number

• Required quantity

• Target market or certification requirement

If the original battery is available, sending a sample to the supplier is even better. The supplier can check size, connector, polarity, cell structure and protection design more accurately.

For new projects or bulk replacement programs, sample testing is strongly recommended before mass production.

Buying Tips for Verifone POS Terminal Batteries

Here are some practical tips for buyers, repair companies and distributors.

Do Not Buy Only by Appearance

Many POS batteries look similar from the outside. The black plastic housing, connector position or label style may look almost the same, but the internal voltage, polarity or communication line may be different.

Always check the original battery model and electrical specifications.

Be Careful With “Universal” Claims

There is no truly universal Verifone POS battery.

A listing that says “suitable for most Verifone POS terminals” should be checked carefully. Verifone terminals have different battery designs across different series. A battery for VX680 may not be suitable for V240m or X990.

Check the Supplier’s Technical Ability

For B2B buyers, price is important, but technical matching is more important.

A professional battery supplier should be able to discuss voltage, capacity, connector, NTC, PCM, cell brand, label, packaging and certification. If a supplier can only confirm by product title, there is a higher risk of mismatch.

Order Samples Before Bulk Purchase

For repair shops, distributors and POS service companies, sample testing can avoid larger losses.

A proper sample test should include:

• Physical fit test

• Charging test

• Full discharge runtime test

• Printing or transaction simulation

• Connector stability test

• Temperature check during charging

• Long standby test

Once the sample is confirmed, bulk production becomes much safer.

Pay Attention to Storage

If batteries will be stored as spare parts, they should not be kept fully discharged for a long time. Lithium-ion batteries are usually better stored with partial charge in a cool and dry environment.

For distributors, warehouse rotation is also important. Older stock should be shipped first to reduce the risk of deep discharge during long storage.

When Should You Choose a Custom Verifone Battery Pack?

A customized battery pack is suitable when the standard replacement option cannot meet the buyer’s requirement.

You may need customization if:

• The original Verifone battery is discontinued.

• The existing battery is hard to find in your market.

• Your customer requires a private label.

• The connector or wire length needs to be changed.

• The battery needs a specific NTC or PCM.

• You need a different capacity within the same size limit.

• You are refurbishing used POS terminals in bulk.

• You need stable long-term supply instead of one-time marketplace purchase.
