Detailed overview: Victron 12V 90Ah gel solar battery
In a solar kit, the battery is the heart of the system: it stores the energy produced by the panels and releases it when needed. This Victron Energy battery uses gel technology (VRLA, Valve Regulated Lead Acid with a gelled electrolyte), meaning it is fully sealed, maintenance-free, and handles repeated cycling better than an equivalent AGM battery.
With a capacity of 90 Ah at the C20 rate (80 Ah at C10) and a 12V nominal voltage, it offers a long service life, rated up to 12 years in float use, with self-discharge below 2% per month at 20 degrees C, useful for equipment stored between seasons. Rugged against shocks and vibration and tolerant of deep discharges, it can be installed in a poorly ventilated space, which suits an off-grid site, a motorhome or a boat.
Victron Energy does not sell to US customers directly; its products reach American buyers through a network of specialty solar and marine dealers instead. This exact battery, part number BAT412800104, is genuinely available in the US at $242.25 through NAZ Solar Electric, a long-established renewable energy retailer, with the item in stock and no minimum order quantity, a real plus over some other Victron resellers that only sell it in six-packs.
It weighs about 26 kilograms (57 pounds) with M8 copper terminals for a solid connection. This is not the kind of battery found on Amazon.com the way Victron's inverters and MPPT controllers sometimes are; sourcing it takes going through a dedicated solar or marine dealer, part of buying into the Victron ecosystem in the US. For anyone building a solar kit meant to last a decade with minimal upkeep, it remains one of the more trusted names in the category, even with that extra sourcing step.

Our tester's review: Julien De Jurquet
Victron doesn't sell to US shoppers directly, and this battery makes that reality clear fast: you won't find it on Amazon.com the way you will Victron's inverters or MPPT controllers. It lives instead with specialty solar and marine dealers, and we tracked it down at NAZ Solar Electric for $242.25, genuinely in stock and ready to ship, no minimum order quantity to wrestle with, unlike a couple of other Victron dealers we checked that only sell it in lots of six. Once it's in hand, the case for it is the same one that has made Victron a benchmark name for years: fully sealed gel construction with no maintenance, no venting fumes, and a rated design life up to 12 years even through repeated deep discharges, the kind of reliability that lets you install it in a poorly ventilated space without a second thought. The honest tradeoff is convenience and price: sourcing it takes a bit more legwork than a one-click Amazon order, and at over $2.50 per amp-hour, you're paying for Victron's name and longevity rather than getting the cheapest gel battery on the market.
Frequently asked questions: Victron 12V 90Ah gel solar battery
Victron does not sell direct to US customers. This battery is genuinely stocked through specialty solar and marine dealers such as NAZ Solar Electric, at $242.25, rather than through Amazon.com or a big-box retailer.
Both are sealed, maintenance-free VRLA batteries. Gel, with its gelled electrolyte, generally handles deep discharges and cycling better and lasts longer, making it well suited to solar; AGM is often somewhat cheaper.
No. As a sealed gel VRLA battery, it needs no water top-ups and produces no venting fumes in normal use, so it can be installed in a poorly ventilated space such as a motorhome or boat locker.
Victron rates it for up to 12 years of service life in float use, with strong cycling endurance. Longevity depends on depth of discharge and temperature: more moderate discharges extend its life further.
