A Deltran Battery Tender Charger has pride in its design and manufacture and, is one of the most technologically advanced marine battery chargers available. Battery Tender's BTP Microprocessor Technology and quick-connect convenience will automatically maintain the batteries in your boat. Their marine battery chargers are ready to go when you are! You just set your Battery Tender charger and forget it, saving you hundreds of dollars in replacement batteries.
Unlike traditional trickle chargers the Battery Tender charger's microprocessor will determine when a battery is fully charged and automatically monitor the voltage for long-term storage. It eliminates the damaging effects of overcharging. If you can't start your boat - you can't use it !
Battery tender chargers do not turn off after they charge the battery. They automatically switch to a safe float voltage level that keeps the battery charged and yet does not do any harm to the battery. In fact, in most cases, this type of charge maintenance will extend your battery’s useful life by at least 50%.
Some customers have reported battery life increases of more than double what they had before using their Battery Tender Charger.
