AccuMate PRO 12V 4A
Powerful, economical 12V smart battery charger.
AccuMate PRO 12V-4A is a versatile automatic compact battery charger for lead-acid starter and deep cycle batteries of minimum capacity 10Ah.
Suitable for all types of batteries: filler cap types; absorbed acid "MF" (AGM) for motorcycles; valve regulated (VRLA); & flooded (wet) & GEL-electrolyte types.
Very easy to use - Connect to battery and mains power. The rest is fully automatic.
In addition to its quick charging ability, AccuMate PRO is ideal for long term maintenance of the batteries of irregularly or seasonally used vehicles & appliances. Here are just a few examples of possible applications: golf trolleys & buggies, 4X4’s, pleasure boats, campers, emergency vehicles, electrical sweepers, handling equipment, etc
No risk of overcharging - AccuMate PRO's special temperature regulated* monitoring circuits vary & regulate the current & voltage according to ambient temperature as long as the batteries remain connected. One month or one year, it makes no difference! * - See temperature regulated charging below.
An internal temperature monitor (NTC thermistor) regulates output current to ensure stable charging conditions.
The easily detachable handle incorporating a cable storage reel and clamp storage can be mounted above the main housing (for carrying) or below (for wall-mounted application, by means of 2 pear-slots in the rear of the housing which engage on two screws in the wall).
The compact charger dimensions of 14 x 16 x 15 cm (5 1/2" x 6 3/8" x 6"high) include the handle.
Intelligent electronic protections against inverse polarity, short-circuit, over-heating with built in spark suppression. Additional fuse protections provided for : eyelets connection set (protects battery against dead-shorting across terminals in case of accident) ; AC input ; and a thermal fuse protects the transformer.
Delivered with battery clips. Replacement and other connection accessories such as eyelets for permanent attachment to a battery's posts or a 2m / 6’ 6” output cord extender or cigar socket connectors are available.
24 months warranty excluding cables, connectors & probes.
Technical specifications:
Comprehensive LED indications - AC power on; BULK - constant current charging ABSORB - constant voltage charging; MAINTAIN - (charge completed) float charging for long term maintenance. Classic 3-stage charging algorithm.
Constant current "bulk" charge until the voltage has risen to 14,4V.
14,4V absorption stage until the charge current falls to 0,17 x full charge current.
Maintenance / Float mode voltage limited at 13,7V. Should the battery being maintained at any stage require current exceeding 0,17 x full charge current, the program reverts to the absorption stage. The battery can then draw current as required until this again reduces to 0,17 x full charge current, whereupon the float mode will again engage.
Temperature regulated charging - only possible with optional plug-in sensor (order code: NTCSENS), highly recommended for deep cycle battery and long term maintenance charging. An ambient temperature sensor plugs in at the rear of the housing to vary the output voltage parameters by -4mV /°C (-2,2MV /'F) per cell away from the 20 °C norm. Unplugging this sensor sets the voltage parameters to the default (20°C) settings.
The optional NTCSENS ambient temperature sensor can be replaced by an optional plug-in 2M (6' 6") long external temperature probe for taping on to the battery casing for more accurate automatic charging voltage management.
