LEAD-ACID · AGM · LEGACY LITHIUM CONVERSION

Battery Replacement Guide
battery systems.

Application-led LiFePO4 conversion for existing battery systems. Compatibility is determined from the voltage window, charger, controller, peak current, tray, terminals, mounting and operating temperature—not from nominal voltage or case size alone.

EQUIPMENT / APPLICATION TYPES

Conversion starts with the existing system.

This page is organized by the battery being replaced and the equipment interface, rather than by end-use industry.

01

Lead-Acid Systems

Review charging profile, usable capacity, voltage behavior and current demand.

02

AGM / GEL Systems

Confirm float charging, low-voltage cutoff, controller and physical installation.

03

Legacy Lithium Systems

Match voltage window, BMS behavior, communication and protection.

04

System-Specific Conversion

Evaluate the complete electrical and mechanical interface before confirmation.

DESIGN PRIORITIES

Requirements that define the battery.

Each industry is reviewed through its own operating and integration constraints.

Voltage window

Nominal, full-charge, cutoff and controller operating limits.

Charger & controller

Charge profile, float behavior, current and equipment control settings.

Load current

Continuous current, acceleration or startup peak, surge duration and regeneration.

Physical fit

Tray, dimensions, terminals, cables, mounting, orientation and temperature.

BATTERY PLATFORM / ARCHITECTURE

A conversion is an interface-matching exercise.

The battery architecture is selected only after the existing electrical and mechanical system has been documented.

Voltage match

Operating window confirmed against equipment and charger

Current match

Continuous, peak and regenerative requirements reviewed

Mechanical match

Tray, terminals, mounting and cable routing confirmed

Control match

Controller, cutoff behavior and communication reviewed

MANLY does not describe a conversion as drop-in or fully compatible until the actual system data has been reviewed.

CONFIGURATION SCOPE

System checks before replacement.

Only the functions required by the equipment are included in the final specification.

  • Voltage window
  • Charger model and settings
  • Controller model and cutoff
  • Continuous current
  • Peak current and duration
  • Regenerative current
  • Tray dimensions
  • Terminal position
  • Mounting and orientation
  • Cable and connector
  • Operating temperature
  • Communication where required

PROJECT INFORMATION REQUIRED

Send the system data before battery selection.

This moves the discussion from a general price request to a configuration that can be checked against the equipment.
