Automatic Charger for 12 V Lead-Acid & 12.8V LiFePO4 Batteries
4-phase self-diagnostic charger for 12 V lead-acid and 12.8 V lithium (LiFeP04) batteries from 2Ah-20Ah.
Can be used with:
Lithium Iron (Ferro) Phosphate battery made up of 4 series connected cells, used in SLI and deep cycle applications. LFP batteries deliver 3-4 times the cranking amps of a similar sized lead-acid battery, with 90% depth of discharge compared to 50-75% for lead-acid. Charged = 13.6 to 13.8V. LFP batteries are sensitive to overcharge and deep discharge. Gross overcharge may cause the battery to overheat and melt down. A dedicated lead-acid charger could damage a lithium battery.
(Absorbed glass mat of VRLA* construction): High concentrate sulphuric acid electrolyte is suspended in fiber glass mats positioned between the lead plates, allowing for a more compact battery design. AGM is dominant in power sport and a popular premium battery option in automotive and marine. Dry charged are only found in powersport, and is delivered with an acid pack. Factory activated AGM receive acid and sealed at source. Charged = 12.7 to 12.9V. * VRLA - Sealed batteries (also known as VRLA = valve regulating lead acid) have a pressure release valve that will permanently release electrolyte gas when overcharged.
A sealed / VRLA* battery with electrolyte a combination of acid and liquid gel that inhibits natural condensation. GEL batteries are popular in stand-by / low
STD batteries, also known as ‘wet cell’ or ‘flooded’ batteries, most with removable filler caps to add distilled water. The liquid electrolyte is a combination of sulphuric acid and pure water. Charged = 12.5 to 12.6V.
To prevent battery damage the OptiMate Lithium charger will shut off if temperature is below -20°C / 4°F or above 45°C / 113°F.
