Tecmate Optimate 3+ Battery Tender


OptiMate 3 desulfater-charger saves neglected, deep discharged batteries other smart chargers can't!
It will safely maintain your vehicle's battery during long term storage.
Hook up the battery and OptiMate immediately checks if the battery is sulfated or not. If it is OptiMate applies "first aid" in the form of a voltage of up to 22V** at low current for up to 2 hours, to recover the battery so it can again accept a charge. It then "bulk" (constant current) charges the battery, the starting stage if no sulfation was detected. Thereafter the unique "verification" (pulsing charge & check) stage provides low voltage desulfating care and tops off the charge. OptiMate then tests & confirms whether the battery can retain sufficient charge to crank an engine before it engages long term maintenance mode. During maintenance it "floats & tests" 30 minutes on, 30 minutes off, so the battery is always 100% ready, but never overcharged.
**The OptiMate's high voltage desulfation mode cannot engage if vehicle electronics / wiring are sensed, so to effectively desulfate a battery, it must be disconnected from the vehicle wiring.

* Recommended for all 12V lead-acid batteries from 2Ah to 45Ah, although it can also maintain larger batteries (it will just take longer to charge).
* Approved by ITS to UL & CSA safety standards for battery chargers.

2 year limited warranty. Service centers in the USA & Canada

* Uses SAE connectors.

Usually ships in 2-3 days
