Batteries & Chargers

Batteries and chargers should be matched as a system, with cell chemistry and voltage checked before use. This NZ collection includes rechargeable cells, vehicle and equipment chargers, replacement batteries and holders rather than only automotive batteries.

Rechargeable cells

Match chemistry as well as size

Cylindrical lithium-ion cells, other rechargeable formats and device batteries have different voltages and charging requirements. A cell that fits physically may still be electrically unsuitable. Check the equipment requirement, terminal style and whether protection circuitry is specified, and do not substitute a higher-voltage rechargeable cell for an ordinary battery based on size alone.

Battery chargers and DC-DC charging

Choose the supported battery profile

Mains and DC-DC chargers serve different charging arrangements. Read the supported chemistry, nominal voltage and charge current for the actual product. A charger labelled for several battery types still needs the correct approved setting and connection, and an alternator-connected charger is not automatically a replacement for a mains charger.

Battery holders and connection parts

Select the required physical arrangement

Holders, snaps, clips and enclosures are accessories rather than batteries. Compare cell count, terminal style, mounting and dimensions with the equipment or project. The resulting voltage depends on the selected cells and connection arrangement, so a holder should not be treated as a complete regulated power supply.

How to Choose Batteries & Chargers

Cell and equipment specification

Match chemistry, nominal voltage, capacity and discharge requirement to the equipment manufacturer instructions. Check flat-top, raised-terminal or solder-tag formats carefully. Avoid using an unverified replacement in a device simply because its cell size or capacity sounds similar.

Charging and handling

Use a charger documented for the exact battery chemistry and configuration. Inspect cells and leads for damage, and follow storage and charging instructions. Do not improvise charging arrangements, mix incompatible cells or assume a larger charge-current rating is suitable for every small battery.

Top Brands in Batteries & Chargers

Digitech: Digitech is the recorded vendor for multi-stage chargers, testers and some rechargeable cells. Check the supported chemistry on each device.

GP: GP is explicitly named on a battery-and-charger listing under an internal vendor. Verify the set contents and cell compatibility.

Grandstream Networks: Grandstream Networks is represented by a dedicated battery charger. It requires the supported battery and equipment.

Powertech: Powertech listings include cells, holders, clips and chargers. These are different component types with separate requirements.

Samsung: Samsung is explicitly identified on lithium-ion cell listings recorded under Powertech. Select by the actual cell specification.

SuperCharge: SuperCharge has a multi-stage vehicle-battery charger listing. Check supported battery voltage and technology.

Uniden: Uniden is represented by a replacement cordless-phone battery. Match the host device and plug arrangement.

Victron: Victron provides mains and DC-DC charging products plus accessories. Compare battery profile, output and system requirements.
