Hello, MūL Technologies customer!

We hope you’ve been enjoying the benefits of your 4 Series MARC robotic cart and experiencing the industry’s fastest ROI on your investment! 

To further protect your investment and improve your experience, we’re proactively sending you a complimentary inter-connect cable that works with your 20Ah battery and the 3A or 5A charger you received.

This upgrade is designed to reduce the risk of creating an arc if the charger doesn’t fully discharge prior to plugging the charger into the battery. By using this new accessory, you can ensure safer, more efficient charging.

You’ll find clear instructions on the use of this cable below. Please follow the directions in the correct order for plugging in the charger, battery and inter-connect cable. 

Thank you for taking this important step in securing the longevity and safety of your equipment. We’re committed to supporting your success with our products. Please let us know if you have any questions or need further assistance on the use of this accessory.

Best regards,
MūL Support Team

P.S.  We’ve recently introduced the new 5 Series MARC products!  We’ve incorporated the features that our customers loved about the 4 Series and added some new features that were also requested.  Review the product specifications and series comparisons here: 4 Series and 5 Series product information.

Keyed battery interconnect cable instructions

The kit includes a 2-part cable like shown in image (1). This cable allows customers to swap batteries on the MARC chargers without waiting for the charger unit to completely discharge.

When using this cable, the following steps should be completed in sequential order. Note that the first step is to unplug the charger unit if it has been left connected to a power source (wall outlet).  The very last step is to plug the charger unit into the 120V outlet to initiate the charging cycle.

Using the interconnect cable

1. If the yellow connector is engaged as shown in (2) pull the connector halves to disconnect it (3). 
   
   Always begin with this step when connecting or disconnecting a charger from a battery.
   
   
   
2. Once you confirm that the charger is not plugged into a 120V wall source, connect the connector from the charger unit to the cable that ends with the female connector (4).
   
   Make sure they are fully engaged, as shown in image (5).
   
   
   
   
3. Connect the cable that ends with the male connector to the charging port in the battery (6). 
   
   Make sure the connector is fully engaged, as shown in image as (7). 
   
   
   
4. Connect the yellow keyed connector (8) as shown. 
   Make sure the connector is fully engaged, as shown in image (9). 
   
   
   
5. Plug the battery charger unit into the source 120V outlet (10).
   Charging cycle will begin.
