Works well even through winter, keeping the 12v battery that powers LED lights in an outside summerhouse charged. Would recommend as good value.

Description
The Optimate Solar Duo 40W 3.3A Charger & Optimiser
OptiMate Solar - the worlds most efficient Solar Pulse Charger, Tester & Maintainer for both lead acid AND lithium batteries. Charger by day, Monitor by night. The new OptiMate Solar range features a smart charger-monitor which automatically adjusts the charge according to the battery type and condition. Battery status information is provided while charging and when the battery is at rest overnight.
OptiMate Solar charge kits are fully automatic. Mount the panel in a suitable location to receive maximum sunlight, hook up the charger-monitor to the battery and walk away. No more battery problems.
When the panel receives sun, the SOLAR CHARGE LED blinks confirming solar power is being delivered and one of the four battery status LEDs (SAVE, CHARGE, MAINTAIN) indicates charge progress. OptiMate Solar converts low solar energy to a high pulse charge which improves solar charge efficiency. When night falls or if the smart charger-monitor senses no solar power is being delivered it changes into a battery monitor with one of the three charge status lights now indicating battery status every three seconds.
