Battery Tender® Product Comparison: Which Charger Is Right for Your Application?
Compare the full Battery Tender® line — from 750mA maintainers to 15-Amp multi-bank chargers — and find the right charger for industrial and fleet use.
The Battery Tender® PowerPlus line is purpose-built for industrial applications — available in 12V 26 Amp, 24V 20 Amp, 36V 18 Amp, and 48V 15 Amp models with IP68 waterproofing and UL marine ignition certification for installation in demanding environments. All PowerPlus models support both lead-acid and Lithium (LiFePO4) battery chemistries via Multi-Chemistry selection and use ISM for automatic 4-stage charging and indefinite float maintenance. For fleet-scale charging and maintenance, the PowerTender® 5-Bank and 10-Bank chargers and maintainers maintain up to 10 batteries simultaneously with independent per-bank ISM control.
Battery Tender® PowerPlus chargers and maintainers address the full voltage range of industrial battery systems: 12V, 24V, 36V, and 48V. The PowerPlus 24V 20 Amp handles floor scrubbers, wheelchairs, and 24V commercial vehicles. The PowerPlus 48V 15 Amp handles forklifts, electric pallet jacks, golf course maintenance equipment, and other 48V industrial applications. All models support both lead-acid and Lithium at the selected voltage and transition to ISM float maintenance automatically after charging is complete.
Yes. The PowerTender® 5-Bank and 10-Bank 4 Amp chargers and maintainers are specifically designed for fleet and institutional charging — each bank runs a fully independent ISM charging cycle at full 4 Amp output simultaneously, supporting up to 10 batteries in any combination of charge state. Per-bank voltage selection (6V or 12V) and per-bank chemistry selection (lead-acid or Lithium) allow the 10-Bank to charge and maintain a mixed fleet of legacy lead-acid and upgraded Lithium batteries simultaneously with the correct profile for each.
Battery Tender® PowerPlus on-board chargers and maintainers carry IP68 waterproofing (full immersion rated), UL marine ignition protection certification (spark-proof for installation near fuel systems), and ETL/CETL safety certification. For industrial and commercial installations requiring compliance documentation, Battery Tender® is manufactured by Deltran Corporation, DeLand, Florida, and has maintained continuous production since 1965 with full UL/ETL certification across the product line.
The primary cause of premature industrial battery failure is sulfation from incomplete or infrequent charging. A Battery Tender® PowerPlus charger and maintainer permanently wired to each piece of equipment ensures the battery is fully charged after every use cycle and maintains float voltage during any period of inactivity. For equipment stored between seasonal or project cycles, continuous ISM charging and float maintenance consistently extends lead-acid battery life from 2 to 3 years to 5 years or more, reducing replacement costs and unplanned downtime across the fleet.
