Battery Tender

<h3>About Battery Tender&reg; by Deltran</h3><p><strong>Battery Tender&reg;</strong> is one of the most recognized and trusted names in battery charging and power management. Founded in 1965 in DeLand, Florida, the brand operates under its parent company, Deltran — a family-owned engineering and manufacturing business with deep roots in power conversion electronics. Deltran&rsquo;s origins lie in power conversion and electronics, eventually pioneering the world&rsquo;s first line of fully automatic smart battery chargers under the Battery Tender name in 1988. That milestone fundamentally changed how vehicle owners think about battery maintenance.</p><h3>Innovation That Keeps Batteries Alive</h3><p>The Battery Tender line of battery chargers revolutionized the industry by incorporating microprocessors that regulate proper charge algorithms and prevent overcharging — a common problem associated with older trickle chargers. Today, that microprocessor-driven intelligence has evolved into Battery Tender&rsquo;s proprietary ISM (Infinite Sequential Monitoring&trade;) technology. ISM delivers a precise 4-stage charge sequence — Initialization, Bulk Charge, Absorption, and Float — preventing the overcharging and sulfation that can permanently destroy batteries.</p><p>Whether you&rsquo;re maintaining a daily driver, a seasonal motorcycle, a stored RV, or a working boat, Battery Tender has engineered a solution for it. Their broad lineup of <a href="/74-battery-tender-battery-chargers-200141">battery chargers</a> spans an impressive range of voltages and chemistries.
