A. The Victron Energy BAT412800085 is rated at 90Ah at the C20 discharge rate. C5 and C10 capacities are not published for this SKU; for precise sizing calculations, refer to Victron Energy's official battery documentation.

Q 2. What terminal type and thread specification does this battery use?

A. The BAT412800085 is fitted with M6 threaded insert terminals, which accept M6 bolts for cable lug connections. This terminal format is common on deep cycle VRLA batteries and allows a secure, low-resistance connection suited to high-current applications.

Q 3. What is the polarity arrangement on this battery?

A. Victron Energy advises that polarity should be confirmed by checking the product label on the battery itself prior to installation. Do not assume a standard arrangement; always verify positive and negative terminal positions before connecting cables.

Q 4. What applications is this AGM deep cycle battery designed for?

A. The BAT412800085 is purpose-built for deep cycle applications requiring sustained high-current discharge and reliable recovery. Typical uses include inverters, electric bow thrusters, electric winches, and off-grid or marine auxiliary power systems. It is not classified as a primary engine-starting battery.

Q 5. What is the design life of this Victron AGM battery?

A. The Victron Energy AGM range, including this 90Ah model, is built to a design life of 7–10 years under normal operating conditions. Actual service life will depend on depth of discharge, charging regime, and ambient temperature.

Q 6. Is the BAT412800085 compatible with start-stop vehicle systems?

A. The AGM technology used in this battery is capable of supporting start-stop functionality; however, suitability for a specific vehicle application must be verified against the product label and vehicle manufacturer requirements. This battery is primarily classified as a deep cycle unit.

Q 7. What are the physical dimensions and weight of this battery?

A. The BAT412800085 measures 380 mm (length) ? 200 mm (width) ? 230 mm (height including terminals) and weighs 22.5 kg. These dimensions should be verified against your battery compartment or tray before ordering.

Q 8. Can this battery be installed in a non-upright orientation?

A. As a VRLA AGM battery, the electrolyte is immobilised within the glass mat separator and the unit is sealed, making it suitable for installation in orientations other than strictly upright. Victron Energy's installation guidelines should be consulted for specific angle limitations.

Q 9. Are there alternative variants or related products available?

A. Yes. BAT412101085 (PID000138951) is listed as an alternative variant within the same Victron Energy deep cycle range. Comparable products from other brands are also stocked on the PartsForMachines platform; use the SKU or product search to identify suitable alternatives.
