Euro MotoElectric batteries are fresh from battery factory production! Then prior to shipping to our customers we maintain our batteries on a Battery Tender. Our Battery Tender shop charger fully charges EME batteries and maintains proper storage voltage until it goes out for shipment. The Battery Tender uses BTP Microprocessor Technology and performs 4-step Charging.

1. Initialization: Monitor Circuit verifies appropriate battery voltage levels and good electrical continuity between the battery and the charger DC output.

2. Bulk Charge: Constant Current at Full Power. Bulk Charge ends at approximately 75% to 80% of full battery recharge.

3. Absorption Charge: Constant Voltage at Absorption Level. This conditions the battery for optimum performance. Absorption charge ends when the battery charging current drops below the optimum recharge threshold or the absorption timer expires.

4. Float Charge: Constant Voltage at Float / Maintenance level. Keeps battery fully charged and maintains high specific gravity. Full charge reset monitor protects battery against excessive appliance current draw while charging. Float charge continues indefinitely.

Your battery is susceptible to damage if overcharged/undercharged. We recommend the use of a voltage regulated battery charger having on charge voltage, at room temperature, at or between 14.4 to 14.6 volts at 68°F (20°C). The only way to determine state of charge of your battery is with a voltmeter.
