Going backwards in time a bit to pulling out the OEM battery, I put some old socks over the terminals of the cables after I disconnected them from the battery. Thank goodness for the built-in handles because this battery is very heavy. I had to stand in the frunk to get the proper leverage to pull out the battery. Even then, my back was not that happy afterwards.

Before installing the Antigravity battery, it is recommended to charge it up to full. I got the Antigravity SC-4 battery charger rated at 4 amps. This is a pretty slick little unit; make sure to select the correct battery type on the charger for the battery that the charger is hooked up to. In this case, it’s li-ion of course! The battery was at 13.2V shortly after I hooked up the charger. You can see the current is only 0.6A and starting to increase.

I noticed the charger gets warm, so I placed it vertical so that it can reject more heat. You can see it’s charging at 4.1A at this point.

The battery read 14.6V when full.

The Antigravity charger has a setting for charging the factory AGM battery too.
