Description
Both versions are VRLA batteries with plate grids cast from a lead-calcium alloy (Pb-Ca). In GEL the electrolyte is fixed as a gel, in AGM it is held in glass mat separators, and in both the valve keeps gas recombination inside the case. Cycle life ranges from 400 to 1,800 cycles, depending on battery type and depth of discharge (DoD). The spread is wide, and a bank cycled shallow lasts several times longer than one run deep every day. Self-discharge is below 2% per month at 20 °C, so a laid-up boat or caravan bank needs only an occasional top-up charge. No water topping is needed in service. Higher voltages are built from 12 V blocks in series, two for 24 V and four for 48 V.
How to choose
Capacity follows daily energy and the planned depth of discharge, since shallow cycling moves life toward 1,800 cycles. Where the bank is fully discharged regularly and space is tight, the AGM Super Cycle lasts at least 300 cycles at 100% DoD in a smaller case. Telecom racks take the Telecom AGM 12 V 200 Ah with front terminals, and partial-state-of-charge duty suits the Lead Carbon 12 V 160 Ah. For years of daily cycling the LiFePO4 Lithium Battery Smart with 2,500–5,000 cycles is the step up, though it needs an external BMS.

FAQ
How many cycles do the GEL and AGM batteries last?
From 400 to 1,800 cycles, depending on type and depth of discharge.
What is the self-discharge of the GEL batteries?
Below 2% per month at 20 °C.
What capacities do the 12 V Deep Cycle GEL and AGM batteries have?
Example models range from 90–270 Ah at 12 V.
Can GEL and AGM Deep Cycle batteries be connected in series for 24 or 48 V?
Yes, two 12 V blocks give 24 V and four give 48 V. Blocks in one string should share type, capacity and age.
Do Deep Cycle GEL and AGM batteries need topping up?
No, these are sealed VRLA batteries and need no water during service.
