Product Description
The CTEK NXT 5 keeps your battery ready for the next trip, whether your rig sits for weeks between adventures or you run a lithium house battery. It charges both 12V lead acid and 12V lithium (LiFePO4) batteries at 4.3A, and its reconditioning mode helps bring deeply drained batteries back to life. Clip it on, pick a mode and walk away: it charges, then switches to maintenance on its own so the battery never overcharges.
