SEALED LEAD ACID Battery This battery is a maintenance-free. Based on the traditional engine start, tractor and deep cycle-style battery. The acid electrolyte moves freely in the cell compartment. The main difference is that the user has no access to top up or add distilled water the individual cells. The manufacturer has ensured that a sufficient amount of electrolyte is in the battery to sustain the chemical reaction under normal use throughout the battery warranty period. CHARGING For this type of battery the typical charge voltage range 14.2 to 14.7 volts; typical float voltage range 13.1 to 13.4 volts. USAGE Popular uses are engine starting and deep cycle designs. It has been found to be reliable for UPS usage.
VLRA – Valve Regulated Lead Acid battery Is a type of sealed lead-acid battery. The valve regulating mechanism allows for a safe escape of hydrogen and oxygen gasses during charging. VRLA batteries are common and found in many applications, such as medical mobility scooters batteries and toy and alarm batteries. AGM – Absorbent Glass Mat technology AGM batteries are a variant of Sealed VRLA batteries, just a more advanced design. Popular usage includes high-performance engine starting, power sports, deep cycle, solar and storage batteries. CHARGING For this type of battery the typical absorption voltage range 14.2 to 15.0 volts; typical float voltage range 13.2 to 13.8 volts. USAGE AGM batteries are common and found in many applications such as RV batteries, boat batteries, motorcycle batteries, UPS & Telecom batteries for generators. Can be used in other applications, such as medical mobility scooters batteries and toy and alarm batteries.
CALCIUM Battery Silver Calcium alloy batteries are a type of lead-acid battery with grids made from lead-calcium-silver alloy, instead of the traditional lead-antimony alloy or lead-calcium alloy. They stand out for its resistance to corrosion and the destructive effects of high temperatures. CHARGING Silver calcium batteries generally require more charging voltage (14.4 to 14.8 V) and deteriorate rapidly in vehicles which do not provide the required voltage range. Alternators which never reach the required voltage range will cause rapid sulfation due to battery never being charged fully. USAGE As a general rule, silver-calcium batteries should not be installed to vehicles or systems which are not specifically designed for silver calcium battery chemistry. This also may occur with static chargers, some of which fail to charge these batteries. Ideal for the installations of Uninterrupted Power supply.
GEL Battery The Gel Cell Battery is similar to the AGM battery style because the electrolyte is suspended, but different because technically the AGM battery is still considered to be a wet cell. The electrolyte in a gel cell battery has a silica additive that causes it to set up or stiffen. The recharge voltages on this type of cell are lower than the other styles of a lead-acid battery. This is probably the most sensitive cell in terms of adverse reactions to over-voltage charging. Gel batteries are best used in VERY DEEP cycle application and may last a bit longer in hot weather applications. CHARGING If the incorrect battery charger is used on a Gel Cell battery, poor performance and premature failure are certain. Battery chargers with gel profile will have information either on the unit or in the manual, about gel compatibility. Typical charging voltage range 14.0 to 14.2 volts; typical float voltage range 13.1 to 13.3 volts. USAGE Gel batteries are not as common as AGM batteries but are often found in deep discharge situations such as wheelchair and medical mobility batteries, trolling motor batteries, and RV deep cycle batteries.
