Telecom batteries are designed for general back up/solar use and telecom applications; they excellent ‘floor space savers’. The deep cycle AGM telecom series has been designed for use in telecom systems. Similarly, these batteries can help solve limited floor space and access problems.
AGM stands for Absorbent Glass Materials. In these batteries the electrolyte is absorbed into a glass-fibre material between the plates by capillary action.
Because of the use of lead calcium grids and high purity materials, Victron VRLA batteries can be stored during long periods of time without recharge. The rate of self-discharge is less than 2% per month at 20⁰C. The self-discharge doubles for every increase in temperature with 10⁰C.
Low Internal Resistance
Accepts very high charge and discharge rates
High cyclic life capability
More than 500 cycles at 50% depth of discharge
VRLA AGM: design life 7-10 years
VRLA GEL: design life 12 years
VRLA GEL 2 Volt cells: design life 20 years
The AGM range has very low internal resistance making them particularly suitable for high current discharge applications such as for inverters.
The GEL model range offer best deep cycle durability and overall longer life. The use of high purity materials and lead calcium grids ensure that for both AGM and Gel products have particularly low self-discharge so that they will not go flat during long periods without charge. Both ranges are supplied with M8 drilled, flat copper terminals ensuring best possible connection contact and eliminating the need for battery terminals. The batteries are compliant with both CE and UL specifications in ABS fireproof containers.
