| CONSTRUCTION - Gel battery construction is as shown in the diagram. The positive and negative grids are cast from a calcium/tin lead alloy to reduce grid growth and corrosion. The active material is manufactured from a high purity lead (99.9999%) to minimize the negative effects of impurities. Separator is manufactured by a world leader in the field, utilizing the latest German technology. The base material is a microporous duroplastic exhibiting excellent high temperature stability and mechanical strength, resulting in very good resistance to vibration and mechanical shock. The integrity of the battery will be maintained under extreme conditions. The purpose of the separator is to maintain a constant distance between the positive and negative plates, totally eliminating the possibility of short circuits whilst allowing the active materials to fully react with the gelled electrolyte. The separator also has an open construction, which allows little resistance to the flow of the electrolyte during filling. A thin layer (typically 0.4mm) of non-woven glass mat is an integral part of the separator and is placed against the positive plate for improved surface contact. |

| The AGM range has very low internal resistance making them particulary suitable for high current discharge applications such as for inverters, thrusters and winches as well as engine starting. 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 particulary 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. Manufactured under ISO 9001 quality standards, they are compliant with both CE and UL specifications in ABS fileproof containers and come with Victron's 2 year world-wide warranty. |
