Frequently Asked Questions - Maintainer 10 GOAL ZERO

What type of battery can I use with the Goal Zero Maintainer 10?

The Maintainer 10 is designed for 12V lead-acid batteries including flooded, AGM, and gel types. It is not suitable for lithium or NiMH batteries.

How long does it take to charge a battery?

Charging time depends on battery capacity and state of discharge. For a typical 12V 50Ah battery, it may take 10-15 hours from deep discharge. The float mode maintains the battery once full.

Can I leave the Maintainer 10 connected indefinitely?

Yes, it is designed for long-term maintenance. Once the battery is fully charged, it switches to float mode to prevent overcharging, so you can leave it connected indefinitely.

Does the Maintainer 10 work with solar panels?

No, the Maintainer 10 requires 120V AC input. For solar charging, consider Goal Zero's Nomad solar panels paired with a compatible charge controller.

What does the red fault LED indicate?

A red LED typically indicates a fault condition such as reverse polarity, short circuit, or battery voltage below 3V. Check connections and battery condition.

Can I charge a completely dead battery?

If the battery voltage is below 3V, the Maintainer 10 may not detect it. Try using a standard charger first to bring it to a usable voltage, then connect the maintainer.

Is the Maintainer 10 waterproof?

No, it is not waterproof. It should be used indoors or in a dry, sheltered location away from moisture and direct sunlight.

What size fuse does the Maintainer 10 use?

It uses a standard automotive blade fuse rated for 2A. If the fuse blows, replace it with the same rating. Check for wiring issues if it blows repeatedly.

Can I charge multiple batteries at once?

No, the Maintainer 10 is designed for single 12V battery charging. For multiple batteries, use a multi-bank charger or charge them separately.

Does it come with a warranty?

Goal Zero typically offers a 1-year limited warranty. Check your purchase documentation for details or contact customer support.

This plug-and-play solar trickle charger prevents the natural battery drain in 12V lead acid batteries found in cars, boats, recreational vehicles, tractors, etc. This natural drain tends to happen when 12V batteries are left unused during an off season. Lead acid batteries last longer when kept fully charged at all times, even when not in use. Also includes a built-in charge regulator to avoid over-charging and reverse discharging.

Position the solar trickle charger where it receives the most direct sunlight as possible and connect to the battery using one of the included connectors. Proven effective during all types of sunlight – including cloudy conditions.

Frequently Asked Questions

Q: What type of batteries can I use? A: The Maintainer can be used on any rechargeable 12V lead acid battery and is designed to provide a trickle charge over time.

Q: How do I know if the Maintainer is charging my battery?

A: The Maintainer's junction box has a light that will illuminate when the solar panel is working. For the best results, position the solar panel so it receives as much full, bright sunlight as possible.

Q: How does the Maintainer attach?

A: The Maintainer can attach to a vehicle's window with the included suction cups, or can be tethered to a vehicle with the built-in loops.
Q: How do I connect the Maintainer to my battery?

A: There are three different connectors depending on your situation - an SAE connector commonly used on motorcycle batteries, alligator clips to attach to typical 12V battery posts, and a 12V connector to charge a battery through the

12V car port. Plug the appropriate connector into the Maintainer's cable and

then attach it to the battery. Q: Can I extend the connecti

A: Yes, 6mm extension cables are available from Goal Zero. Although you can extend the cable, keep in mind a longer connection will decrease the efficiency of the Maintainer.

Q: Do I need a charge controller?

A: No, the Maintainer has an in-line charge controller to ensure you'll never over-charge your battery. This built-in protection makes the Maintainer an eas plug-and-play solution to keep your batteries healthy when not in use.

Q: Can I use the Maintainer outdoors? Yes, the Maintainer has been designed and engineered to be a durable charging

system that can be used outdoors in any weather.

Q: How long does it take to charge my battery?

A: The Maintainer is designed to keep your battery at a healthy charge level when it's not in use, not to completely charge an empty battery. If you are looking for a way to charge a battery quickly (i.e. an RV battery after watching T) we suggest the Guardian 12V

TV), we suggest the Guardian 12V Charge Controller.

Q: Can I start or drive my vehicle while the Maintainer is connected to the battery? A: Yes, it is safe to operate a vehicle with the Maintainer attached. If you are using the suction cups on a windshield, make sure the Maintainer is not a distraction in your field of vision.
