How It Charges

How the Maintainer 10 Trickle Charger Works:

This plug-and-play solar trickle charger prevents the natural battery drain in 12V lead acid batteries found in motorcycles, 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 charger regulator to avoid over-charging and reverse discharging.

Position the solar trickle charger when 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.


How the Maintainer Works


  • 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 included depending on you 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 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.
  • Q: Can I extend the connection?
  • A: Yes, 6mm extensions cables are available on this website. 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 easy, plug-and-play solution to keep your batteries healthy when not in use.
  • Q: Can I use Maintainer outdoors?
  • A: 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.
