The SLA Valve Regulated Battery is the preferred choice for UPS systems, Alarm and Emergency Lightning systems, for Medical equipment, wheelchairs and mobility scooters.

Unlike the regular lead acid battery, the SLA is designed completely sealed with no liquids inside and gas recombinant.

The working principal of the SLA battery is the same as normal lead acid battery but constructional features brings advantages over. Acid in Sealed AGM batteries remains absorbed in glass mat and can not be spilled even if casing is broken, thus makes SLA battery non dangerous and provides ability to install it in any position on its side or at any angle. Another main advantage is gas recombination technology. When any lead acid battery in state of discharging or recharging process it starts producing hydrogen and oxygen which are highly explosive gases, therefore normal lead acid batteries should have sufficient ventilation and sparks and flames must be kept away of them. Gas recombination technology in Sealed Lead Acid Batteries does not let hydrogen and oxygen to escape but recombines it back in to the water, which gets absorbed by glass mat.

The valve regulated technology is installed in each sealed lead acid battery to allow some gas to escape during overcharge or fast charge, when the gassing is so rapid that recombination can not keep up and some amount of gas has to go out to prevent battery damage. As soon as gas escaped the SLA battery it can not be toped back up, therefore overcharging or equalization is not recommended for Sealed Lead Acid batteries

SLA battery with AGM technology has no any liquid inside and lead plates are compressed with glass mat fibres so hard that no any movement produced inside the battery, thus makes them are very resistant to vibration

Internal resistance of SLA battery are so low that self discharge is only 1-3% per month, where normal lead acid discharges at about 1% per day. Low self discharge increases shelf life, SLA batteries start to loose they performance after 18 month of shelf life

The SLA is not subject to memory. No harm is done by leaving the battery on float charge. The SLA battery can be stored for two years, but must remain in charged state. Leaving it in discharged condition causes sulfation, a condition that makes the SLA difficult, if not impossible to recharge. The SLA battery should not be discharged below 1.75V per cell, nor can it be stored in discharged state.

Lead acid batteries are not environmentally friendly and have to be recycled properly
