- Complete description of the product Charger & Maintaining battery optimate 1 Duo 12V - Intelligent Maintenance lead and lithium)

Extend the life of your batteries and avoid failures when starting with optimate Tecmate Battery Charger 1 Duo. Impairable reference in the field of electrical maintenance, this smart device is designed to load, optimize and maintain at the top of their performance all 12 volts batteries from 2 to 30 Ah.

Thanks to its technology Duo, this optimate automatically adapts its load program for both traditional lead-acid batteries (liquid electrolyte, MF sealed agm, gel) than modern technology batteries Lithium (LifePO4) used in competition or on recent vehicles. Delivering a mild continuous current of 0.6 a, It is ideal for a long-term permanent connection (wintering) without any risk of overload or degradation of the elements. Its advanced recovery function allows it even to detect and restart the load on deeply discharged batteries until 4 volts.

Comes complete with a durable case, wall fasteners, its waterproof cable to leave on the vehicle and a set of standard crocodile clamps, the optimate 1 duet is the essential equipment for your workshop or garage.

- The trick in Michel (the corner of the expert)

* "Hi mechanical enthusiasts! If there is a profitable investment in a garage, it's a good battery lifeer like this optimate 1 duet. How many times have we seen new karting, motorcycle or collecting car die in two months during the winter simply Because they stayed flat in the cold ?

My booth trick to keep your immortal batteries: the permanent connection and the quick connector !

Which is great with tecmate, it's the original waterproof battery cable provided in the carton. Do not bother the crocodile pliers each time! Attach the eyelets of the watertight cable directly to the + and - terminals of your battery (on your kart, motorcycle or mower) and let the small fast SAE quick connector be exceeded under the hood or tub.

As soon as you enter session or store the vehicle for several weeks, you just have to clip the optimate 1 duet in one second. The device takes care of everything: it analyzes the state of the battery, adjusts its load to 0.6 A without heating the plates, and flip into Floating Main mode. You can leave it connected 6 months in a safe way, it consumes nothing and guarantees you a quarter-turn start in the spring! "*

-FAQ SEO (Frequently Asked Questions)

Q: Does the Optimate 1 Duo switches automatically between lead mode and lithium mode ?

A: Yes I do. Thanks to its intelligent microprocessor, the charger analyzes the electrical response of the 12V battery connected and adapts its charging profile (voltage and current curves) depending on whether it is a conventional lead-acid battery (STD / AGM / GEL) or a lithium battery (LIFEPO4). You have no switch to tilt.

Q: Can I leave the Optimate 1 duet plugged into my battery year round without risk of fire or overload ?

A: Absolutely. This is the main function of this device. Unlike traditional chargers that continue to send current and boil the electrolyte, the Optimate 1 Duo integrates total overload protection, overheating and short circuits. If the battery is disconnected or short circuit, the unit stops autonomously.

Q: Can this charger recover a battery completely flat at 0 volts ?

A: Optimate 1 Duo integrates a low voltage recovery program capable of desulfatting and reinforcing the load from a dropped battery until 4 volts. If a 12V battery has come down below the 4V bar (0 to 3V), the internal cells are generally irreversibly damaged, but for the majority of accidentally deep discharges, the Optimate will save it.
