Choosing a replacement lithium battery

Check the existing system before replacing its battery.

Application illustration. Configuration is confirmed by model.

The short answer

A replacement lithium battery should be selected against the existing system’s voltage, current, charger and physical installation. SAAN GWAN’s replacement portfolio includes lithium batteries for lead acid replacement and low speed electric vehicle applications. Similar capacity or dimensions do not establish that a battery is a direct replacement.

Which existing system details matter?

  1. Voltage and current

    Provide the existing battery configuration, system voltage and continuous and peak current demand.

  2. Charger and controller

    Share charger and controller models and settings. Confirm charging voltage, charging profile and protection compatibility with the manufacturer.

  3. Fit and connection

    Check battery dimensions, weight, terminal type, polarity, cable arrangement and mounting requirements.

  4. Connection and use

    Confirm whether series or parallel operation is permitted for the exact model and application. Share the operating temperature and installation environment.

What should you compare?

Selection areaWhat to review
Lead acid replacementCompare the required voltage, charger suitability, current demand and battery compartment.
Electric mobility applicationReview motor controller requirements, peak load, mounting and the approved system configuration.
Optional featuresConfirm which communication, monitoring or other optional functions are included in the offer.

A common oversight

A lithium battery is not automatically a drop in replacement. Do not reuse an existing charger or connection scheme without checking compatibility.
