À propos de ce produit
The Fullriver DC series is a true deep-cycle AGM range: thicker plates and a higher lead content than conventional batteries deliver more reserve capacity and more cycles under repeated deep discharge. Sealed, valve-regulated and completely maintenance-free, the DC85-12 is our standard recommendation for house banks in the tropics, on boats and in off-grid homes alike — it tolerates heat, vibration and the daily charge/discharge cycle.
More of the capacity you paid for
Fullriver rate the DC series to an 80% depth of discharge — their own published limit — where much quality AGM is held to 50%. On this 85 Ah battery that is the difference between planning around 43 Ah and planning around 68 Ah, so a smaller, lighter bank can carry the same night away from the mains. Deep cycling is still work: a bank that is fully recharged after every use will outlast one that isn’t, so pair it with a multi-stage AGM charger set up with temperature compensation. In tropical heat that one setting protects your investment more than anything else you can fit.

Chargement
Charge with an AGM profile. Fullriver specify 14.7 V bulk/absorption and 13.7 V float at 25 °C, temperature-compensated at −4 mV/°C per cell, and a bulk current of about 20% of the 20-hour capacity — roughly 17 A for one DC85-12, or 34 A for a pair. Matching multi-stage chargers: Kisae Abso AC1220 20 A for one battery, Kisae Abso AC1240 40 A for a pair, and for a 24 V bank of four the Kisae Abso AC2450 50 A (24 V).

Sealed and non-spillable — classified non-hazardous for transport (49 CFR 173.159(d), IATA A67/A48), so it ships by air, sea or road with no dangerous-goods surcharge and can be mounted in any orientation except inverted. Every battery is bench-tested in our Trang warehouse before dispatch.

Téléchargements
Building a house bank with the DC85-12
Two DC85-12 in series give 24 V 85 Ah; two of those pairs in parallel give 24 V 170 Ah (4.1 kWh stored, about 3.3 kWh usable within Fullriver's 80% limit). Four in parallel give 12 V 340 Ah. Keep every cable in a parallel set the same length, fuse the bank at the battery, fit the temperature sensor to a middle battery, and replace a bank as a set rather than one battery at a time.
Charging a 24 V bank of four: bulk current of about 34 A, so the Kisae Abso AC2450 50 A 24 V charger from a generator or the mains, or a 24 V solar controller sized to your panels. Size the bank and the cable, or send us what you run on DOUBLER and an engineer will check it.
As a second battery in a 4x4, pickup or camper
Fitted in the canopy or under a seat, the DC85-12 gives 68 Ah of usable energy at Fullriver's 80% depth of discharge: enough for a 35–45 L compressor fridge, LED lights and phone charging for a night without starting the engine. It is sealed, so it can be mounted on its side, and it shrugs off corrugations.
Charge it from the vehicle with a DC-DC charger rather than a split-charge relay, so a smart alternator and a long cable run still deliver a full AGM charge: for this battery the KISAE Abso DMT1230 (30 A). Every KISAE charger comes with a free temperature sensor and its page carries the manufacturer's cable and fuse table. Add a battery monitor and you can see the state of charge instead of guessing.
On a longer trip the battery is topped up as you go: an hour's driving on a 30 A DC-DC charger returns about 27 Ah, and 200 W of solar on the roof about 50 Ah a day in Thai sun, so a fridge, lights and phones (about 40–50 Ah a day) keep going for a week or more.

Questions
Do I need a DC-DC charger, or will a relay do?
Many modern vehicles have smart alternators that lower the voltage once the starting battery is full, so a relay leaves an AGM battery part-charged. A DC-DC charger gives it the full AGM profile Fullriver specify (14.7 V absorption, 13.7 V float); the dual-battery guide explains why.
Can it be mounted on its side?
Yes. It is sealed and non-spillable, so it can be mounted upright or on its side, which gives you more options in a canopy, under a seat or in a locker.
How do I look after it in the heat?
Mount it shaded with some airflow, and charge it with temperature compensation: Fullriver specify −4 mV/°C per cell, and the battery temperature sensor that does this comes free with every compatible KISAE charger.
