America's most trusted smart battery charger and maintainer — backed by a 10-Year Limited Warranty that no competitor in the industry matches — built by the company that invented the modern battery maintainer in DeLand, Florida in 1965.\u003c\/p\u003e\u003ch3\u003eBuilt for Cars. Safe for Everything.\u003c\/h3\u003e\u003cp\u003eThe Battery Tender® Plus 1.25 Amp is engineered for automotive batteries up to 80Ah — the correct size for most passenger cars, compact SUVs, pickup trucks, and light commercial vehicles. At 1.25 Amp, it charges automotive batteries efficiently without the heat risk of higher-output chargers, and ISM (Infinite Sequential Monitoring™) ensures it never overcharges regardless of how long it remains connected. It is equally safe for smaller powersports batteries, making it the single charger for every vehicle in your garage.\u003c\/p\u003e\u003ch3\u003eWhy the Plus Beats Every Trickle Charger — and Most Smart Chargers\u003c\/h3\u003e\u003cp\u003eStandard trickle chargers deliver constant current regardless of battery state. Connected to a fully charged battery for two weeks, a trickle charger will overcharge it — producing heat, excessive gassing, electrolyte loss, and accelerated plate corrosion that permanently reduces capacity.

Cold reduces electrolyte conductivity and requires higher charge voltage to reach full capacity; heat accelerates overcharge risk and electrolyte evaporation. The Battery Tender® Plus automatically adjusts charge voltage based on ambient temperature throughout the entire charging cycle — increasing voltage in cold storage conditions to ensure complete charging and reducing it in summer heat to prevent damage.\u003c\/p\u003e\u003ch3\u003eSafety Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpark-proof connection technology\u003c\/strong\u003e — No current flows until polarity and connection integrity are confirmed, protecting vehicle electronics, ECUs, and alternators\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReverse polarity protection\u003c\/strong\u003e — Automatic shutdown if clamps are reversed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShort-circuit protection\u003c\/strong\u003e — Fault detection with automatic shutdown\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eETL and CETL certified\u003c\/strong\u003e — Independently tested and certified for safety in the United States and Canada\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eStop Replacing Batteries. Start Maintaining Them.\u003c\/h3\u003e\u003cp\u003eThe leading cause of premature battery failure is sulfation — the permanent, irreversible hardening of lead sulfate crystals on battery plates that occurs when a battery sits discharged. Unlike surface corrosion, sulfation is a physical structural change to the battery's lead plates. Once significant sulfation has formed, no charger can restore the lost capacity. The Battery Tender® Plus prevents sulfation from forming in the first place by keeping the battery at peak float voltage from the moment it is connected. Battery life consistently extends from 2–3 years to 5 years or more.\u003c\/p\u003e\u003ch3\u003eThe 10-Year Warranty Difference\u003c\/h3\u003e\u003cp\u003eBattery Tender® backs the Plus with a 10-Year Limited Warranty — the longest warranty on any battery charger in the industry. Most competitors offer 1 to 5 years. A 10-year warranty is not a marketing claim; it reflects the component quality, manufacturing standards, and product confidence that Battery Tender® has maintained since its founding in DeLand, Florida in 1965.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e10-Year Limited Warranty | Designed and Engineered by Deltran Corporation, DeLand, Florida Since 1965\u003c\/strong\u003e\u003c\/p\u003e","brand":"Battery Tender®","offers":[{"title":"Default Title","offer_id":52241549197586,"sku":"021-0128","price":64.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1929\/4483\/files\/battery-tender-default-title-battery-tender-plus-1-25-amp-12v-battery-charger-and-maintainer-021-0128-59387711914353.png?v=1777901453","url":"https:\/\/hdwerks.net\/products\/battery-tender-plus-1-25-amp-12v-battery-charger-and-maintainer","provider":"HDwerks ","version":"1.0","type":"link"}
