COMMON FEATURES

Smart Charging & Protection Features

Available functions vary by model. Review the selected product specifications and operating instructions before use.

Automatic Staged Charging

The range includes multi-stage, 3-stage and 10-stage charging programs depending on the selected model.

Temperature Compensation

Listed models adjust charging behavior according to ambient-temperature conditions to reduce undercharging or overcharging risk.

Charge-Completion Control

Smart control reduces or stops charging when the programmed full-charge condition is reached.

Electrical Protection

Reverse-polarity, short-circuit and overcharge protection are listed across the range. Additional over-voltage, over-current, over-temperature and spark-free functions vary by model.

Charging-Status Display

The listed variants provide charging and battery-status information through LCD, standard-display or color-display interfaces.

Pulse Recovery

Pulse-repair functions are intended only for compatible lead-acid batteries under suitable discharge or sulfation conditions.

Features vary by model. Do not assume that every function is included in every variant.

BUYER GUIDE

How to Choose the Right Smart Battery Charger

01

1. Match the Battery Voltage

Use SWT-3612 for a compatible 6V or 12V battery. Use a 12V-only model for 12V batteries. Choose SWT-1205, SWT-1206, SWT-1508, SWT-1608, SWT-2010 or SWT-2025 when both 12V and 24V charging are required.

02

2. Confirm the Battery Chemistry

Select the correct charging mode for AGM, GEL, flooded or WET lead-acid, standard lead-acid or LiFePO4 batteries as permitted by both the charger and battery manufacturer.

03

3. Check the Listed Ah Range

Choose a charger whose listed battery-capacity range includes the battery you intend to charge.

04

4. Confirm the Allowed Charging Current

Do not choose current by charging speed alone. The charger output must not exceed the battery manufacturer’s maximum recommended charging current.

Approximate charging time depends on the amount of capacity that must be replaced. Dividing the required amp-hours by charger current gives only a rough constant-current estimate. Actual total time is longer because charging current tapers and electrical losses occur.

FUNCTION COMPARISON

Battery Charger vs. Battery Maintainer vs. Jump Starter

Product Type Main Purpose What It Does Not Do
Battery Charger Restores battery energy over time through a controlled charging program It does not provide the same instant cranking current as a jump starter
Battery Maintainer Keeps an already charged battery near its target level during storage It is not intended to rapidly recharge a deeply discharged battery unless the device also includes a charging function
Jump Starter Provides a short high-current burst to help crank an engine It does not fully recharge or maintain the vehicle battery

A jump starter may get a vehicle running after an accidental discharge, but it does not restore the battery’s full state of charge. A smart charger is used to recharge the battery and may also provide maintenance functions. A physically damaged or irreversibly aged battery should be tested and replaced rather than repeatedly repaired.

RECOVERY MODE

What Can Pulse Repair Mode Actually Do?

Pulse repair mode is intended for compatible lead-acid batteries affected by certain discharge or sulfation conditions. It may improve charging acceptance in some cases, but the result depends on battery condition.

Pulse repair cannot repair a cracked battery case, electrolyte loss, an internal short circuit, physically damaged plates or irreversible battery aging. It also cannot guarantee that a battery will recover its original capacity.

Do not use a lead-acid pulse-repair program on a lithium battery unless the selected charger mode and battery manufacturer explicitly permit it.

B2B CUSTOMIZATION

OEM & Private-Label Smart Battery Chargers

CNLI supports charger customization for distributors, wholesalers and private-label brands. Confirm the required electrical specification and market configuration before production.

Brand Logo & Product Label

Apply confirmed customer branding and product-label information.

Confirm Certification by Model and Market

Certification and document availability vary by charger model and destination market. Ask CNLI to confirm the exact model number, applicable standard and available report or declaration before placing an order.

Do not assume that a certificate or test report issued for one charger automatically covers another model, output specification or market.

FAQ

12V & 24V Smart Battery Charger FAQ

How do I choose the correct battery charger?

Confirm the battery voltage, chemistry, capacity in Ah and the battery manufacturer's maximum recommended charging current. Then use the comparison table to select a model whose output and listed battery-capacity range match those requirements.

Which model on this page supports 6V batteries?

SWT-3612 is the only listed 6V-capable variant on this page. It provides 6V 1.5A or 12V 1.5A output and has a listed battery range of 2–30Ah.

Which models can charge both 12V and 24V batteries?

The dual-voltage models are SWT-1205, SWT-1206, SWT-1508, SWT-1608, SWT-2010 and SWT-2025. Their 24V output ranges from 5A to 15A.

Can these chargers charge AGM, GEL and flooded lead-acid batteries?

Compatibility with AGM, GEL and flooded or WET lead-acid batteries is listed across the product range. Select the correct charging mode and confirm the requirements of the specific battery before use.

Can these chargers charge LiFePO4 batteries?

LiFePO4 compatibility is listed for the models on this page. Use only the charger's lithium-compatible mode and confirm the charging voltage, current and BMS requirements of the battery. Do not use a lead-acid pulse-repair mode on a lithium battery.

What does pulse repair mode do?

Pulse repair is intended for compatible lead-acid batteries affected by certain discharge or sulfation conditions. It may improve charging acceptance in some cases, but it cannot repair physical damage, internal short circuits or irreversible aging.

Can a smart charger recover a completely dead battery?

Not always. A battery below the charger's detection threshold, affected by an internal fault or damaged by irreversible aging may not accept charging. Battery condition should be tested when recovery does not begin normally.

Can I leave the charger connected after the battery is full?

The listed smart chargers include automatic full-charge control, but continuous-connection behavior depends on the exact model and selected charging mode. Follow the operating instructions supplied with the specific charger.

How long will it take to charge a battery?

Charging time depends on the amount of capacity that must be replaced, charger current, battery condition and the charging stage. Dividing the required amp-hours by charging current provides only a rough estimate; total charging time will normally be longer.

What is the difference between a battery charger and a jump starter?

A battery charger restores battery energy over time. A jump starter supplies a brief high-current burst to crank an engine but does not fully recharge the vehicle battery.

Which models include engine-start assistance?

SWT-1608, SWT-2010 and SWT-2025 include a listed 200-second booster mode intended to assist starting a 12V vehicle.

Can the charger plug, connector and packaging be customized?

Yes. Available project options include branding, packaging, AC input plugs, DC output connectors, cable length and connector wiring. Final availability must be confirmed for the selected model and order.

What information should I send for a model recommendation?

Send the battery voltage, chemistry, capacity in Ah, permitted charging current, required connector, application, target country and estimated order quantity.

Are the certifications the same for every charger model?

No. Certification and document availability can vary by model, electrical specification and destination market. Confirm the exact model and required standard before ordering.

Which lithium charging modes does SWT-2025 support?

SWT-2025 lists LiFePO4 charging modes at 14.6V / 29.2V. Match the selected mode to the battery chemistry, charging voltage, permitted current and BMS requirements. These mode specifications apply to SWT-2025; confirm other models separately.

What are the SWT-2025 packaging specifications?

SWT-2025 is packed 8 units per carton. Carton size is 50 × 38.2 × 24.5 cm with a gross weight of 12.5 kg. Each unit weighs 1.15 kg net and 1.44 kg packed; unit packaging measures 24 × 18 × 11.5 cm.
