Q: What is a AGM battery?
A: The newer type of sealed non-spillable maintenance free valve regulated battery uses “Absorbed Glass Mats”, or AGM separators between the plates. This is a very fine fiber Boron-Silicate glass mat. These type of batteries have all the advantages of gelled, but can take much more abuse. These are also called “starved electrolyte. Just like the Gel batteries, the AGM Battery will not leak acid if broken.
Q: What is a Gel battery?
A: A gel battery design is typically a modification of the standard lead acid automotive or marine battery. A gelling agent is added to the electrolyte to reduce movement inside the battery case. Many gel batteries also use one way valves in place of open vents, this helps the normal internal gasses to recombine back into water in the battery, reducing gassing. “Gel Cell” batteries are non-spillable even if they are broken. Gel cells must be charged at a lower voltage (C/20) than flooded or AGM to prevent excess gas from damaging the cells. Fast charging them on a conventional automotive charger may be permanently damage a Gel Battery.
Q: What is advantages and disavantages of lead-acid batteries?
A: Advantage: low price: the price of lead acid batteries is just 1/4~1/6 of that of other types of batteries with a lower investment which most users could bear.
Disadvantage: heavy and bulk, low specific energy, strict on charging and discharging.
Q: What’s the payment term?
A: 30% will be paid by TT after signed contract (Confirmed PO); 70% will be paid before shipment.
Q: How about the delivery time?
A: 50-70 days depends on different battery, will be confirmed before order.
