Brand: OptiMATE Battery Chargers
The Gold Series Optimate7 dual-voltage model is a selectable, automatic 8-step charger that is suitable for 24/7/365 maintenance of just about any 12 volt or 24 volt lead-acid automotive or motorcycle battery between 10Ah and 120Ah 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 12 volt or 24 volt lead-acid battery (wet cell, gel cell, AGM, RG, Ca-Ca, deep cycle, or SLI/starter-type) and select the battery voltage. There is never a risk of damage due to overcharging. Like all Optimate chargers, the Optimate7 starts with 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 a charge), and finally to OptiMATE Smart Maintenance. If you disconnect the battery, the charger will automatically shut down.
If the battery is deeply discharged, the automatic SAVE routine can rescue most batteries discharged as low as 0.5 volts. If the battery is fully charged when the charger is connected, the Optimate7 will help to compensate for normal power drains by alarm systems, stereo memory, ECU, etc. The 10 Amp (12V) / 5 Amp (24V) maximum charging current can charge a 12V, 100Ah battery or a 24V, 50Ah battery in about 24 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). 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.
* OptiMate rates this charger for use on 12V batteries from 10AH to 240Ah and on 24V batteries from 5Ah to 120Ah.
