The VSM 422 uses battery type information to accurately compute State of Charge. To obtain the greatest precision when measuring State of Charge, input your battery type into the VSM 422 when performing initial setup or changing battery types.
The following table will help you determine your battery type:
| Battery Type | Common Brands | Model | Identifying Characteristics |
|---|---|---|---|
| Flooded Acid Reserve | Rolls Surrette Exide | Varios Models Stowaway® | Modular Construction Marine Deep Cycle Removable Caps |
| Flooded Low Maint. | West Marine® Deka | SeaVolt® Deep Cycle Marine Master® Flooded | Combination Terminals Combination Terminals |
| Flooded Conventional | Exide® Trojan® | Golf Cart Golf Cart | Universal Post Terminals Not Maintenance Free |
| AGM Standard | West Marine® Exide® | SeaVolt® Deep Cycle AGM Select Orbital® Deep Cycle | Maintenance Free Maintenance Free |
| AGM Acid Staved | NorthStar EnerSys® | Energy1 ODYSSEY® | Maintenance Free Maintenance Free |
| Gel | West Marine® Exide® | SeaGel Prevailer® | Maintenance Free, immersible Maintenance Free, Dual-terminal |
Although choosing the wrong battery type will not result in large errors in State of Charge measurement, this information helps the VSM 422 select an open circuit voltage curve and self-discharge attributes characteristic of a particular battery style. Entering the correct battery type will result in optimal accuracy of the VSM 422’s State of Charge monitoring.
