Automatic models recognize batteries via current, voltage and charging profiles, but they frequently fail to identify battery types correctly. Battery aging, deep discharge, third-party BMS conflicts and defective detection chips are all common causes of recognition errors.

Manual switching eliminates these risks entirely, keeping your batteries charged safely and reliably.

Since you rarely need to adjust charging modes, manual operation is never a bother. Meanwhile, auto-detection mistakes can end up costing you a great deal.

How to choose the right model for your damaged converter?

Models of power converters are WF-8955-MB, WF-8955-AD-MBA, WF-8955LIS-MBA.

WF-8955-MBA is used for lead-acid batteries, WF-8955LIS-MBA is used for lithium batteries, and WF-8955-AD-MBA can be used for both lead-acid and lithium batteries.

So if your original converter model is WF-8955-MBA or WF-8955-AD-MBA and the battery is lead-acid, you should choose the lead-acid version.If your battery is lithium, select the lithium version.

If you want a converter that can charge two types of batteries, then choose WF-8955-AD.
