Safety Information:

• Always wear safety glasses when working with batteries.
• Always use a voltage regulated battery charger with limits set to the above ratings.
• Overcharging can cause the safety valves to open and battery gasses to escape, resulting in premature failure. These gasses are flammable!
• You cannot replace water in sealed batteries that have been overcharged.
• Any battery that becomes very hot or makes a hissing sound while recharging should be disconnected immediately.
• Failure to fully charge a battery can result in poor performance and a reduction in capacity.
