What are the differences between gel
batteries and absorbed glass mat
(AGM) batteries?
Both are recombinant batteries. Both are sealed valve-regulated
(SVR) – also called valve-regulated lead-acid (VRLA). AGM batteries
and gel batteries are both considered ″acid-starved″. In a gel
battery, the electrolyte does not flow like a normal liquid.
The electrolyte has the consistency and appearance of petroleum
jelly. Like gelled electrolyte batteries, absorbed electrolyte batteries
are also considered non-spillable – all of the liquid electrolyte is
trapped in the sponge-like matted glass fiber separator material.
The ″acid-starved″ condition of gel and AGM batteries protects
the plates during heavy deep-discharges. The gel battery is more
starved, giving more protection to the plate; therefore, it is better
suited for super-deep discharge applications.
Due to the physical properties of the gelled electrolyte, gel battery
power declines faster than an AGM battery’s as the temperature
drops below 32ºF. AGM batteries excel for high current, high power
applications and in extremely cold environments.
Terms and condition
Warranty
All batteries are warrantied for a period of 1 year from date of dispatch. This warranty covers
manufacturing defects only. Accidental damage is not covered in this warranty. It is
essential that you check the batteries on delivery to make sure that they have reached you
in good condition. Any damage to the batteries that has been done prior to you
receiving them must be notified to us within 2 days of delivery and the battery will be replaced.
It is essential that you carefully check the batteries upon receipt to ensure that they have
not been damaged in transit.
Any subsequent damage to equipment, fixtures or fittings caused by the fitting of damaged
batteries is not covered in this warranty and no responsibility is accepted for this damage.
It is entirely the responsibility of the purchaser to ensure that the batteries are undamaged
when fitted. It is particularly important to ensure that there are no cracks in the body of the
battery as this could cause leaking of acid.
If a battery is found to be cracked please store the battery with the crack facing upwards
until the battery is collected or disposed of.
