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.\u003c\/p\u003e\u003ch3\u003eIP68: The Highest Waterproof Rating in the Battery Tender® Lineup\u003c\/h3\u003e\u003cp\u003eIP68 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.\u003c\/p\u003e\u003ch3\u003eUL Marine Ignition Protection\u003c\/h3\u003e\u003cp\u003eIn 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.\u003c\/p\u003e\u003ch3\u003eMulti-Chemistry: Lead-Acid and Lithium\u003c\/h3\u003e\u003cp\u003eA 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.\u003c\/p\u003e\u003ch3\u003eISM: 4-Stage Charging at 26 Amp\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInitialization\u003c\/strong\u003e — Battery health check and polarity confirmation before current flows\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBulk Charge\u003c\/strong\u003e — Full 26 Amp output restores depleted capacity rapidly\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbsorption\u003c\/strong\u003e — Current tapers automatically as the battery approaches full charge, preventing overcharge damage for lead-acid and Lithium alike\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFloat Maintenance\u003c\/strong\u003e — Correct maintenance protocol for the selected chemistry delivered 24\/7, indefinitely\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eCompatible battery size range: 40Ah to 400Ah at 12V.
