SOLAR BATTERIES

AGM batteries differ from flooded lead–acid batteries in that the electrolyte are held in the glass mats, as opposed to freely flooding the plates. Very thin glass fibers are woven into a mat to increase the surface area enough to hold a sufficient amount of electrolyte on the cells for their lifetime. The fibers that compose the fine glass mat do not absorb and are not affected by the acidic electrolyte. These mats are wrung out 2–5% after being soaked in acids just prior to finish manufacturing. AGM cells are leak-proof due to the captive electrolyte and do not need much ventilation under normal conditions, this feature makes them very reliable solar battery banks.

Deep cycle lithium batteries are helping to revolutionize the battery industry. These batteries do not use traditional lead-acid battery technology to carry an electrical charge. The batteries move lithium ions from the anode to the cathode during discharge. The ions are transferred back when charging.

The design is more durable and lighter weight. A deep cycle lithium battery can weigh up to 80% less than a comparable lead-acid battery. It is also more resistant to vibration and shock.
