PowerPlus 12V 26 Amp Battery Charger and Maintainer

$299.95

Description

The Battery Tender® PowerPlus™ 12V 26 Amp is engineered for both portable use and permanent on-board installation — equally at home as a wall-mounted shop charger or wired directly into a vessel or vehicle. The highest-output 12V model in the PowerPlus™ line, it delivers 26 Amp charging for large marine house batteries and commercial vehicle battery banks with IP68 waterproofing, UL marine ignition protection, and Battery Tender®'s ISM (Infinite Sequential Monitoring™) intelligence built in.

IP68: The Highest Waterproof Rating in the Battery Tender® Lineup

IP68 certification exceeds IP67 — providing complete dust protection and water immersion resistance at manufacturer-specified depth, typically 1.5 meters or greater. Where IP67 is suitable for outdoor mounting with rain and splash exposure, IP68 is the rating required for bilge-adjacent installation, submersible-environment mounting, and any location where prolonged water exposure is possible. The PowerPlus™ 12V 26 Amp can be permanently installed in locations that no other Battery Tender® charger can survive.

UL Marine Ignition Protection

In enclosed marine spaces — engine rooms, bilge compartments, fuel storage areas — electrical sparks can ignite fuel vapors with catastrophic results. UL marine ignition protection is an independent certification that the PowerPlus™ 12V 26 Amp will not produce a spark capable of igniting a fuel vapor mixture during normal operation or connection. This certification is a requirement for any charging device installed in an enclosed marine space and is not found on standard portable chargers.

Multi-Chemistry: Lead-Acid and Lithium

A chemistry selector delivers the correct ISM charging profile for either lead-acid (flooded, AGM, GEL, sealed MF) or Lithium (LiFePO4) batteries. As marine vessels transition from lead-acid to Lithium house battery systems, the PowerPlus™ 12V 26 Amp supports both chemistries at full 26 Amp output without requiring a charger change.

ISM: 4-Stage Charging at 26 Amp

  • Initialization — Battery health check and polarity confirmation before current flows
  • Bulk Charge — Full 26 Amp output restores depleted capacity rapidly
  • Absorption — Current tapers automatically as the battery approaches full charge, preventing overcharge damage for lead-acid and Lithium alike
  • Float Maintenance — Correct maintenance protocol for the selected chemistry delivered 24/7, indefinitely

Compatible battery size range: 40Ah to 400Ah at 12V. Lead-acid: flooded, AGM, gel cell, sealed MF. Lithium: LiFePO4.

Applications

  • Marine vessels with large 12V lead-acid or Lithium house battery banks
  • Commercial and fishing vessels requiring bilge-area or engine room installation
  • Large RVs and campers with high-capacity 12V battery systems
  • Commercial trucks and vehicles with large 12V battery banks
  • Industrial equipment requiring on-board or wall-mounted charging
  • Any 12V application requiring IP68 protection and UL marine ignition certification

Automatic Temperature Compensation

Charge voltage adjusts automatically based on ambient temperature — increasing in cold conditions to ensure complete charging, reducing in heat to prevent overcharging. Essential for marine and industrial environments where temperature variation is significant and manual adjustment is impractical.

Safety Features

  • UL marine ignition protection — certified safe for use in fuel vapor environments
  • Spark-proof connection — no current flows until connection is confirmed correct
  • Reverse polarity protection
  • Short-circuit protection
  • IP68 sealed housing
