Verify connections, assure that they are clean. If the battery is dirty, or if any minor amount of acid has spilled onto the case, check cleaning section of this manual. Any fluid on or around the battery could indicate damage or improperly sealed case.

M8 (TP08) 9.6-10.7 Parallel/SerieS COnneCtiOnS: Certain applications demand more voltage or more capacity than one battery’s output. By arranging the connection configuration, one is able to increase the output voltage, output capacity or both if needed. To increase voltage, connect the batteries in series as shown in Figure 1.

RoLLS AgM BATTERY CHARgiNg iNSTRUCTioNS To maximize the life of your Rolls battery, it is important that it is properly charged. Over and under-charging a Rolls battery will result in shortened service life. The best protection from improper charging is the use of a quality charger and routinely checking that the charger current and voltage settings are maintained.
Page 8
The charger can maintain the current B indefinitely or until the charger is shut off or unplugged. This stage is ideal to maintain battery state of charge. Make sure the temperature compensation is programmed as specified in Figure 1 (-4mV/°C/cell or -2mV/°F/cell) or manually adjust the voltage setting for temperatures varying from...

(5% of the 8 or 20 hour rate). The rate may be increased if the battery does not begin to gas. Do not let the cell temperature exceed 115° F (46° C). If the temperature becomes excessive or the cells begin to gas vigorously, reduce the rate of charge.
2. Wet batteries are fully charged and tested before shipping, but do self-discharge during transportation and storage. The first charge brings the battery to an operational state. Before this charging process, the cell electrolyte level should be checked, making...
3. Check for correct polarity. Attaching the positive and negative voltmeter lead to the positive and negative battery terminal should give a positive voltage reading. If it is negative, a reverse polarity condition exists and you should contact your dealer or Rolls Battery Technical Support.
Most chargers on the market have a timer that allows the user to adjust the duration for the required time to return the battery to full charge. In order to set the correct time, a simple calculation is required. With the help of the 20 AH...
“not hold a charge”. These symptoms are typical of a heavily sulfated battery. If a battery is not being fully charged on a regular basis or limited equalization is performed using a generator, sulfating will occur from “deficit”...
2. Set the charging controls to the recommended equalization settings according to voltage. 3. Charge at a low DC current (5 A per 100 AH of battery capacity). If grid power is not available, use solar panels or a good DC source when possible. At high voltages, charging with generator can be difficult and hard on the inverter.
Regardless of the size of the battery bank, the probe should be installed on the side of one battery, below the liquid level on a battery placed in the center of the bank. The main factor to look for is maximum temperature. The battery bank should not exceed an operating temperature of 50ºC.
Batteries must NEVER be disposed in household waste. To reduce environmental impacts, bring your battery to a certified recycling depot at the end of its life. Note: Lead-acid batteries are 97-98% recyclable. Rolls Batteries have >66% recycled lead.
SHIPMENTS SHOULD BE THOROUGHLY INSPECTED FOR DAMAGE BEFORE SIGNING THE DELIVERY SLIP. The Company will replace or, at its option, repair any Rolls Battery sold by it that fails to conform to the warranty stated above on a NO CHARGE BASIS as follows: For warranty terms and conditions, please refer to the Products section on the website for model-specific details: www.rollsbattery.com.
