How long does it take to charge a motorcycle battery with a battery tender?

To be safe, assume that the batteries require a full 100% charge after the cells are filled. For example, a 16 Ah battery will take about 13 hours to get to the absorption voltage (constant 14.4 Volts). It may take another 6 to 8 hours to reach the float voltage (constant 13.2 Volts).

How long does it take to charge a motorcycle battery on a trickle charger?

The 65Ah battery in my car, will take 18.5 hours to charge. On my bike battery charger at 6Amps from completely flat, it will take 11.25 hours to charge 9ah battery. The charger should adjust to a maintenance charge once it's full, assuming it is a half polite charger!
  • How much is a new battery for a motorcycle?

    That's a maximum of $57.50 for a new battery charger, maybe less. If you consider the fact that a brand new motorcycle battery from the dealer will typically cost you $100-150, is it worth it? Let's see the statistics. Lead Acid Batteries (AGM or Wet Cell alike) have an average of 3-5 years of life.
  • How do you remove a motorcycle battery?

    Always use the correct size socket on your socket wrench when removing and replacing the bolts on the battery, otherwise you can strip the bolts.
    1. Step 1: Locate your battery.
    2. Step 2: Remove the negative cable.
    3. Step 3: Remove the positive cable.
    4. Step 4: Remove the old battery and drop in the new one.
  • What is a trickle charger?

    A trickle charger is a car battery charger designed to be left on a car for a long period of time to re-charge the battery. It slowly adds the charge to the battery and does not allow for the normal depletion of charge that batteries commonly have.

What voltage should I charge my motorcycle battery?

A healthy 12 volt motorcycle battery should maintain a range from 9.5 - 10.5 volts under the load for a good 30 seconds straight. If the battery begins to hold and then steadily drops in voltage, there is a problem.
  • Can you use a car battery charger to charge a motorcycle battery?

    Large automotive-type battery chargers, designed to charge a good-sized car or truck battery, can easily overcharge a small motorcycle battery if you're not careful. Unfortunately, in some circumstances, that may be the only type of charger available. Yes, it's a pain, but it's better than cooking your battery.
  • How do I know if my motorcycle battery is good?

    Starting Load Test
    1. Adjust voltmeter to DC volts (20 volt range).
    2. Place voltmeter leads to the battery terminals. ( positive to positive and negative to negative)
    3. Watch the voltmeter as you start your motorcycle.
    4. If the voltage drops below 9.5 volts, the battery has very low capacity and should be replaced.
  • Can you load test a deep cycle battery?

    With a battery load tester, apply a load of at least one half the battery's CCA rating for 15 seconds and wait five to ten minutes. If the battery's electrolyte is above 110o F (43.3o C), allow it to cool. The Open Circuit Voltage will vary for gel cell and AGM type batteries so check the manufacturer's specifications.
