Brand: OptiMATE Battery Chargers
The Optimate 2 Duo X2 is a fully-automatic 5-step charger that is suitable for 24/7/365 maintenance of just about any 12 volt automotive or motorcycle batteries. Its dual-chemistry design lets you use it on lead-acid, gel cell, AGM, RG, and even lithium (LiFePO4) batteries! It is sealed against weather (IP54 or higher) so it can be used indoors or outdoors, in temperatures down to -4°F (-20°C). This X2 version can charge two batteries at once, even if they are different types. Perfect for charging your on-board battery and grid starting battery between races.
Just hook it up to your 12 volt batteries and forget it! The Optimate 2 Duo does the rest, even figuring out what types of batteries are connected. There is never a risk of damage due to overcharging. Like all Optimate chargers, the Optimate 2 starts with an automatic test of battery condition. If all is well, the 5-step charging proceeds from Low Volt Start, to Controlled Charge, to Optimize, and finally to OptiMATE Maintenance. If you disconnect the battery, the charger will automatically shut down.
The Optimate 2 Duo X2 can save most batteries discharged as low as 4 volts. If the battery is fully charged when the charger is connected, the Optimate 2 Duo X2 will help to compensate for normal power drains by alarm systems, stereo memory, ECU, etc. The 2 Amp per channel output is recommended for lead-acid batteries between 6Ah and 96Ah capacity or LiFePO4 batteries between 2Ah and 24Ah.
Operates on 100 - 240 VAC input voltage (50-60Hz). This version has a 6 foot AC supply cord with a 2-prong North American (USA & Canada) plug. Draws less than 0.5W when not connected to a battery (listed by the California Energy Efficiency Commission). Includes 2 clamp-type charging cables and 2 weatherproof ring terminal cables, each with a quick-release 2-pin SAE plug that connects to the 6 foot charge leads on the charger. The charger body features built-in wall mounts.
