Primary and rechargeable products serve different designs

The EVE consumer battery business includes both primary and rechargeable products. Before selection, establish whether the device uses a replaceable primary source or contains an approved charging circuit.

ER and CR belong to primary battery families, while small lithium-ion cells, cylindrical rechargeable cells and PLM are considered separately. Similar dimensions do not make these groups interchangeable.

For maintenance, the original marking and power circuit are more useful than the generic term battery. In a new instrument, the power architecture should be agreed with the designer alongside the maintenance strategy and intended service conditions.

Meters, sensors and telemetry loads

For an autonomous instrument, distinguish standby consumption, measurement, processing and data transmission. A device may remain asleep for most of its operating period yet require a specific short pulse when its transmitter activates.

Include this sequence and the temperature conditions in the enquiry. A primary cell, SPC and an ER+SPC combination represent different supply items and are selected against the circuit. For an existing meter or sensor, provide the instrument designation and approved documentation.

For development work, a table of operating modes helps the technical discussion address the complete electronic design rather than only average consumption.

Housing choices for compact electronics

In a compact device, capacity must be considered together with available space, the circuit board, terminals and mechanical support. Pouch and Bean Cell products address different packaging requirements, so selection begins with a drawing.

Include the connection method, insulation requirements and compatibility with the approved charge controller. If a sample is required, define its designation and acceptance criteria before ordering. The particular version is approved after evaluation in the device.

This keeps electrical requirements connected to the mechanical design, especially when a prototype becomes a production product with repeatable procurement and assembly requirements.

Power tools and small equipment

EVE cylindrical cells are presented for multiple applications, including tools, cleaning robots and light electric vehicles. Their load profiles differ even where similar housing formats are used.

A tool enquiry should describe working cycles, while autonomous equipment also needs operating duration and charging behaviour to be considered. When the requirement is a replacement battery assembly, provide the assembly designation rather than only the cell name.

The technical review includes the circuit, protection, contacts and dimensions. Individual cells and complete assemblies should be listed separately so that the requested supply scope remains clear to all parties.

Complete markings and variant suffixes

Trade descriptions often shorten a series name, whereas an accurate purchase order requires the complete product designation. A suffix may identify a housing or terminal variant; its meaning should be checked in the documentation for the selected item.

Do not apply a specification from one model to another because their names look similar. Include photographs of the cell and its connection, together with the original line from the equipment parts list.

If a different variant is proposed, compare the relevant parameters and obtain technical approval. Each ordered item then has a clear identification and an agreed basis for selection.

Preparing a useful procurement request

Start with the complete marking on the product and a clear photograph of the label. Add the application, quantity, terminal arrangement and delivery destination.

If the equipment documentation contains both an internal customer code and an EVE designation, provide both: the name of a finished device may differ from the cell installed inside it. A previous approved specification is useful for repeat orders, particularly when changes are highlighted.

For a new design, include the power requirements and available installation space. This information distinguishes a request for individual cells from a battery assembly or a complete system.

Electrical requirements and load profile

Describe the operating voltage window, average consumption, maximum current and duration of peak loads. A capacity figure alone does not explain how a battery behaves in the intended application.

State whether the equipment runs continuously, wakes periodically from standby or operates only during an outage. For rechargeable products, include the charger characteristics and control requirements. These inputs allow the appropriate variant to be discussed against its documentation.

When comparing proposals, use equivalent test conditions: initial state, temperature, discharge current, end voltage and duty cycle. Keep the equipment requirements separate from unverified claims about a particular product.

Dimensions, terminals and installation

A photograph beside a ruler can support preliminary identification, while the final selection should follow an agreed drawing. Provide dimensions, tolerances, polarity, terminal type, connector and mounting arrangement.

Products that look similar may differ in tabs, leads, attachment points or mechanical support requirements. When replacing a component inside an existing assembly, include the connection drawing and the assembly identification.

The equipment owner or responsible engineer should confirm the proposed variant. An agreed mechanical specification helps prevent a situation in which an electrically suitable cell cannot be fitted correctly into the instrument or battery module.

Operating and storage conditions

Describe the ambient temperature and the temperature inside the enclosure, exposure to moisture, vibration, ventilation and standby periods. Storage conditions before installation are also relevant to the supply specification.

Check the documentation of the selected variant rather than applying the temperature range of a neighbouring product family. Separate normal operation from short duration extremes. For outdoor installations, vehicles or cabinets with limited cooling, provide the applicable project requirements.

Considering the installation environment at the enquiry stage helps align the selected battery with the actual operating conditions rather than relying only on the information printed on its housing.

Documentation and batch traceability

Record the full designation, specification revision, quantity and required accompanying documents in the order schedule. For production programmes, define how batches will be identified and how markings will be retained.

The applicability of transport documents and test reports is checked against the agreed product and shipping method. Label photographs, packing lists and technical specifications serve different purposes and do not replace each other.

If your organisation follows a specific incoming inspection procedure, provide it before quotation. Requirements for documents, samples and inspection can then be included in the agreed order instead of being introduced after dispatch.

Samples and production quantities

For a new application, it is useful to separate technical sample evaluation from the subsequent production order. State which parameters your organisation will test and who is responsible for approving the application.

Retain sample results together with the product designation and the documentation revision. Before moving to volume supply, agree requirements for consistent construction, packaging and identification. For equipment already in service, an approved parts list can provide the starting point.

A change in chemistry, housing or connection arrangement is treated as a design change and should be agreed by the responsible specialist before an order is placed.

Supply scope and delivery planning

An enquiry can include several items, each with its own quantity and purpose. Separate cells, assembled modules, cables and additional components so that both purchasing and engineering teams can review the scope. Provide the delivery destination, preferred batch sequence and packaging requirements.

Battery transport requires an agreed shipping arrangement and appropriate terminal protection. Following technical clarification, the proposal identifies the products and their supply scope.

Compare this schedule line by line with the original enquiry to ensure that a required variant or accessory has not been omitted. Keep delivery planning linked to the final agreed configuration.

Availability, price, lead time, supply scope, transport documentation and compatibility are confirmed in the proposal for the identified product. This page does not establish authorised distributor or service status, or identical specifications across variants.
