Brand: OptiMATE Battery Chargers
The Gold Series Optimate7 dual-voltage model is a selectable, automatic 7-step charger that is suitable for charging and 24/7 maintenance* of just about any 6 volt or 12 volt lead-acid automotive or motorcycle battery between 10Ah and 240Ah capacity.* It is sealed against weather (IP54) so it can be used indoors or outdoors, in temperatures down to -40°F (-40°C).
Just hook it up to your 6 volt or 12 volt lead-acid battery (wet cell, gel cell, AGM, RG, deep cycle, spiral cell, or Ca-Ca/Calcium-ion) and select the battery voltage. There is never a risk of damage due to overcharging. Like all Optimate chargers, the Optimate7 starts with a safety check of connection polarity, followed by an automatic Test of your battery condition and voltage. If all is well, the 4-step charging proceeds from AmpMatic Charge, to Optimize, then Test (checking if the battery will hold the charge), and finally to OptiMATE Smart Maintenance. If the Test step finds that the battery is deeply discharged, charging begins with a special Save step.
The Optimate7 can save most batteries discharged as low as 0.5 volts. If the battery is fully charged when the charger is connected, the Optimate will help to compensate for normal power drains by alarm systems, stereo memory, ECU, etc. The AmpMatic charging automatically adjusts charging amperage depending on the battery's needs, including ambient temperature. The 10 Amp maximum charging current can charge a 100Ah battery in about 12 hours (assuming no other power drain is present).
Operates on 100 - 240 VAC input voltage (50-60Hz). This version has a 6 foot long 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). If you disconnect the battery with the charger still connected to AC power, the Optimate7 will automatically stop charging and enter Eco mode. Includes clamp-type charging cable and weatherproof ring terminal cable, each with a quick-release 2-pin SAE plug that connects to the 6 foot charge lead on the charger. The charger body features built-in wall mounts.
* For long-term monitoring, OptiMate recommends checking connections and electrolyte levels (if applicable) at least every 2 weeks.
