Give your motorcycle the attention it deserves with a Deltran Battery Tender. Deltran makes chargers that fully charge a battery then automatically switch to a maintenance mode when the charge is complete! There has been some confusion in the battery charger world that trickle chargers are simply maintainers ---- NOT TRUE! Each and every Deltran Battery Tender Battery Charger® regardless of its size is programmed with a microprocessor that will correctly charge a battery then automatically switch to a maintenance/float mode. Make sure to purchase your Deltran motorcycle products from Motorangutan.
