Product Description

12V 40Ah H7 Sodium-Ion Start-Stop Car Battery

Automotive sodium-ion starter battery developed for passenger cars, frequent engine restarting and customized H7 or PN3 battery replacement projects.

Product Overview

The Chalongfly 12V 40Ah sodium-ion start-stop battery is developed for passenger cars and compact vehicles that require reliable engine cranking and frequent restart capability.

The product is positioned around an H7 or PN3-style automotive battery format and can be customized according to the original battery tray, terminal layout, mounting structure and vehicle electrical system.

A smart battery management system monitors voltage, current, temperature and operating status. Cranking current, enclosure dimensions, terminals, protection parameters and branding are confirmed according to the target vehicle.

Exact dimensions, weight, CCA, terminal layout and charging parameters are confirmed according to the final vehicle application.

Designed for Frequent Engine Restarting

Start-stop vehicles may restart the engine repeatedly during urban driving. The battery system must provide rapid cranking current while supporting repeated operating cycles.

Rapid Cranking Response

The sodium-ion battery is configured to deliver short-duration high-current output for compatible gasoline or diesel engine starting.

Frequent Restart Capability

The battery is positioned for vehicles that experience repeated engine shutdown and restart events during daily urban operation.

Application-Specific Configuration

Cranking current and BMS parameters are selected according to engine displacement, fuel type, charging system and operating temperature.

H7 and PN3 Battery Fitment

Automotive batteries with similar capacity can use different housings, terminal arrangements and mounting bases. Fitment must therefore be confirmed against the original battery before production.

Battery Tray	Length, Width, Height and Mounting Base
Terminal Layout	Positive and Negative Terminal Position
Terminal Type	Automotive Post or Customized Terminal
Hold-Down Structure	Customized According to Original Battery Tray

Smart Battery Management System

The integrated BMS monitors the battery and provides protection against abnormal electrical and temperature conditions.

Overcharge Protection	Over-discharge Protection
Over-current Protection	Short-circuit Protection
High-Temperature Protection	Low-Temperature Protection
Cell Voltage Monitoring	Cell Balancing

Passenger Car Applications

Start-Stop Passenger Cars Vehicles requiring repeated engine restart capability	Urban Taxis High-frequency daily urban vehicle operation
Ride-Hailing Vehicles Passenger fleets with frequent starting cycles	Compact Delivery Vans Stop-and-go delivery and service vehicle operation
Fleet Passenger Vehicles Customized batteries for vehicle fleet projects	OEM Automotive Projects Customized electrical and installation integration

Frequently Asked Questions

Is this battery designed for start-stop vehicles?

Yes. It is positioned for compatible vehicles that require frequent engine restarting. Complete electrical-system compatibility must be confirmed before installation.

Is every H7 battery exactly the same size?

No. Exact dimensions, mounting bases and terminal layouts can vary. The original battery measurements must be confirmed.

Can it replace an AGM start-stop battery?

A replacement battery can be developed after checking voltage, CCA, dimensions, charging system, terminal layout and start-stop control compatibility.

What is the confirmed cranking current?

The cranking-current rating is confirmed according to the engine, original battery specification, minimum temperature and final battery design.

What information is required for customization?

Please provide the vehicle model, engine information, original battery voltage, capacity, CCA, dimensions, terminal layout and charging-system voltage.
