12-Volt battery maintainer

This two-pack supplies 1.5 watts of amorphous solar power to keep 12-volt batteries topped up on cars, boats, SUVs and tractors. It connects directly through the included wiring and connectors without needing mains electricity. The panels work in cold weather to help ensure reliable starts through winter months.

Capacity and headroom

Each panel delivers 1.5 watts, which is enough to offset the slow self-discharge of a healthy 12-volt battery during storage or infrequent use. It will not recover a deeply discharged battery or sustain loads that draw more current than the trickle output provides. The amorphous cells still produce some current in overcast or low-light conditions.

Amorphous cell type

Amorphous silicon performs better than crystalline alternatives in diffuse or shaded light, making it suited to variable outdoor conditions. The kit includes only the panels, wiring and connectors; a battery is not supplied. Buyers who need faster charging or higher wattage for larger battery banks should look elsewhere.

Questions about this item

Will the 1.5 W amorphous panel keep a 12 V car battery topped up through winter?

Yes — each maintainer delivers a trickle charge to a 12 V battery without needing mains power, and the pair can be placed on separate vehicles.

How can I verify the panel is producing power after I mount it?

Connect the supplied wiring to the battery; a rising voltage on the battery terminals in daylight confirms output.

Does the kit include the battery and mounting hardware?

The box contains two solar maintainers with wiring and connectors; the 12 V battery and any brackets or fixings must be purchased separately.
