Right now my battery tender waterproof 800 0.75 amp takes quite a while.** A: This is not a charger in the conventional sense. These (and your Battery Tender) are made to MAINTAIN a charge. If your battery is dead/low you need a regular battery charger to fully charge it, then use this to maintain your charge. Your Battery Tender is only providing less than 1 amp in charge, that's why it takes forever.
