The Deka Intimidator AGM battery is likely the most rebranded AGM battery there is.

This AGm does not have the super low self discharge of Odyssey or Northstar or Lifeline AGM, Nor the super high CCA figures of Odyssey/Northstar, nor the deep cycle attributes of Lifeline's super thick positive plates.
The Deka Intimidator, like many budget AGMS, also has a 30% maximum charge rate, meaning 30 amps maximum for a 100AH battery. 14.4v is the absorption voltage.
If you deeply cycle one of these, approach that 30% rate, charge to 14.4v @77f, and hold 14.4 until amps taper to 0.5% of the 20hr capacity, or 0.5 amps per 100Ah of capacity.
Ignore the 'trickle charge' crowd regarding proper charging of a depleted AGM. Trickle chargers will tickle one of these to death if it is cycled deeply.
If it is never discharged below 95%, it does not really matter though, but an unintentional discharge requires a high amp recharge to 100% full, not just a jump and a drive around the block.
Even though Deka says to limit initial current to no more than 30%, the battery itself, when depleted below 75% state of charge, can ask for way more than this with a large charging source available, like an Alternator spinning fast. If exceeded, the battery could vent, and these low resistance batteries might overheat an alternator trying to recharge it from a depleted state.
AGMs really dislike being kept under 100% charged, more so than flooded/wet batteries, so it behooves you to keep it as close to 100% charged as possible, and this means do not rely on the alternator to achieve this, especially if the vehicle sits for prolonged periods, or ever needs a jumpstart.
Far too many people assign superbattery status to AGMs because of their price and marketing, but they are finicky princesses who must be kept happy or they turn into your malignant Ex wife.
