Can you charge deep cycle batteries with an alternator?

Most vehicle alternators will never properly and fully charge up a Deep Cycle battery so invest in a good charger or a solar arrangement with a charge controller/regulator with at least a three stage charging control (many chargers are now 6 or 7 stage affairs).

Can I charge a deep cycle battery with a car battery charger?

Q: Can I use a battery charger designed for deep cycle batteries to charge a regular car battery? Yes you can.

How many amps should you charge a deep cycle battery?

What amp rate should you use for a deep cycle battery? It’s best to use a charger that provides between 5 and 15 amps for a deep cycle battery, and this is exactly the range in which most deep cycle marine battery chargers come.

Can you trickle charge a deep cycle battery?

Trickle chargers definitely work for marine batteries because they don’t generate excess heat. During a standard charge, the battery heats up. It’s certainly safe to touch, but these issues occur within the battery, including: Internal materials slowly break down.

Can I use a trickle charger on a deep cycle battery?

Can you charge a deep cycle battery with a trickle charger?

A trickle battery charger will charge a battery at the same rate as the battery’s self-discharge, which is how quickly a battery’s capacity falls during storage.

Will a 2 amp charger charge a deep cycle battery?

Therefore, your charger’s amp rating’s choice depends on the amp-hour rating of the deep cycle battery. For example, a small 12-volt deep cycle battery can be charged with a 2 amp rated charger. A 100 amp-hour deep cycle battery should be charged with a higher amp rating of 10 amp and above.

Can my stock alternator charge two batteries?

A car alternator will be more than capable of charging two batteries. However you need to be more careful about connecting two batteries together if one is charged and the other is not.

At what voltage should a deep cycle battery be charged?

Charging – Flooded Types Deep Cycle Batteries in a cycling application require a recharging voltage of 2.43 to 2.45 volts per cell. This is 14.6/14.7 volts for a 12 volt nominal installation and 29.2/29.4 volts in a 24 volt site.

How long should you charge a deep cycle battery?

A charger with 15 amps, for instance, will take about two hours to fully charge a battery at a 25-percent discharge value. Chargers with only 5 amps, however, will need a full six hours with the same battery.

How do you charge a second battery with an alternator?

You can easily use your alternator to charge your second (auxiliary) battery simply by connecting the positive terminals of both batteries so that they’re in parallel.
