What Battery Tender does

Battery Tender (legal entity Deltran Corporation) is a third-generation, family-owned designer, manufacturer, and distributor of battery maintenance products headquartered in DeLand, Florida (Volusia County), founded in 1965. The company builds a broad portfolio spanning 750mA consumer maintainers, multi-amp smart chargers (up to 40A professional units), portable lithium jump starters (600A-2000A peak), 2-in-1 Charge N Start combined units, multi-bank marine onboard chargers, industrial PowerPlus high-voltage chargers (12V-48V), Level 1 and Level 2 home EV chargers, solar panels and controllers, and supporting accessories. Its core technical platform is the proprietary ISM (Infinite Sequential Monitoring) 4-stage charging algorithm (Initialization, Bulk, Absorption, Float) plus Charge N Store storage maintenance, with support for flooded lead-acid, AGM, gel, and Lithium (LiFePO4) chemistries; marine and industrial SKUs carry IP67/IP68 ratings and UL marine ignition protection.

The company sells primarily direct-to-consumer through batterytender.com and through more than ten major U.S. retail chains (Walmart, Costco, Menards, AutoZone, Advance Auto Parts, RevZilla, J&P Cycles, Dennis Kirk, Blain's Farm & Fleet, Hodges Marine) plus Amazon, with a B2B reseller portal serving wholesale and fleet accounts. Pricing is one-time/perpetual across a ladder from $29.95 (solar controller) to $849.95 (10-bank fleet charger), with no subscription or recurring component. End customers span individual vehicle owners, powersports enthusiasts, boat owners, classic car collectors, RV/outdoor users, farmers, and commercial fleet/industrial operators across the U.S. and Canada.

Revenue mechanics rest on hardware unit sales of branded smart chargers, jump starters, EV chargers, and accessories, distributed through a multi-channel retail and direct-to-consumer mix, supplemented by B2B reseller and authorized dealer programs.
