NEXPEAK 1.75A 2-Pack Battery Charger for 6V & 12V Lead-Acid Batteries — 7-Stage Maintenance with LCD

NEXPEAK’s 2-pack 1.75A charger is a compact 4-in-1 battery solution that charges, maintains, trickle-charges and helps desulfate 6V and 12V lead-acid batteries.

Small but feature-rich, these two portable chargers are built for long-term maintenance of automotive, powersport, marine and deep-cycle lead-acid batteries. Each unit uses a 7-stage charging program with pulse repair technology and an LCD to show charging status, percentage and voltage. The chargers also include safety protections and both alligator and ring connectors on a 6.6 ft SAE cord for flexible installation.

How does this charger protect and extend battery life?

The NEXPEAK charger uses staged charging and pulse desulfation to help remove sulfation and restore some lost capacity in lead-acid batteries. Intelligent monitors prevent overcharge, reverse connection, and overheating so the battery is conditioned rather than stressed.

• 7-stage algorithm: desulfation, trickle, constant current, constant voltage, detection, compensation, float
• Pulse repair mode to address sulfation on idle or weak batteries
• Comprehensive protections: short-circuit, overload, reverse polarity, over-temperature
• Auto restart into previous mode after power interruptions

What battery types and vehicles are supported?

These chargers are compatible with most 6V and 12V lead-acid chemistries, including flooded, gel, AGM, SLA and VRLA. They are not designed for lithium battery chemistries and will not charge batteries below the minimum voltage threshold.

• Suitable for cars, motorcycles, ATVs, UTVs, boats, lawn mowers, golf carts, RVs
• Works with deep-cycle and starter batteries of supported chemistries
• Cannot charge lithium batteries or cells under 0.3V
• Use mode selection per battery type; hold MODE 5 seconds to force 12V

How do I use the display, modes and connectors?

The backlit LCD gives real-time voltage, current and charge percentage so you can confirm the battery’s condition while charging. Choose STD mode for automatic cut-off at full charge or Trickle mode to maintain battery voltage long-term; cables include both ring and alligator clips for permanent or temporary connections.

• LCD shows charging state, percentage, voltage and current
• STD mode automatically stops when full; Trickle mode maintains voltage
• Detachable alligator and ring terminals on 6.6 ft SAE cord for convenience
• Press MODE for five seconds to force 12V charging mode

Is it safe to leave the charger connected for months?

Yes—designed for long-term maintenance, the charger supports extended connection and will automatically enter trickle or float mode to preserve battery health while minimizing risk. Built-in safety layers reduce the chance of damage during unattended charging.

• Float/trickle modes keep batteries topped without overcharging
• Multiple protections guard against over-voltage, over-current, temperature and polarity errors
• Auto-restart resumes previous mode after power loss
• Not suitable for permanently damaged batteries or unsupported chemistries

Who is this for: NEXPEAK’s 2-pack 1.75A chargers are ideal for vehicle owners, seasonal equipment caretakers, and fleet managers who need reliable, compact maintenance chargers for 6V and 12V lead-acid batteries. If you want visible charging data, long-term float capability, and pulse desulfation in a plug-and-forget format — these chargers give two units for multi-vehicle setups, storage garages or backup use. Review the usage notes before connecting and do not attempt to charge lithium batteries or batteries below the minimum voltage threshold.
