## Description

**Deep Cycle batteries**: 12V cyclic AGM and GEL for motorhome, marine, mobility scooter and small-mid off-grid solar. 50-260 Ah. Ritar, Fullriver and MK selection.
"Deep cycle" means designed to handle 50-80% discharges repeatedly — vs a cranking battery that only tolerates 5-10% before degrading.

## Deep Cycle — for repeated deep discharge

A cranking (SLI) battery is built to deliver high current for 1-3 seconds then recharge to 100%. A deep cycle battery delivers moderate current for hours and survives 500-1,500 cycles at 50% DoD. Essential for motorhome, marine house bank, mobility scooter and solar.

| Technology | Cycles 50% DoD | Life | Application |
|---|---|---|---|
| Cyclic AGM | 500-700 | 5-7 yr | RV, marine, chair |
| GEL | 700-1200 | 6-8 yr | Mobility, moderate solar |
| FLA T-105 | 1200-1500 | 5-7 yr | Family off-grid solar |

### **AGM or GEL?**

AGM gives best cost/cycles ratio for normal use. GEL handles deeper discharges and lasts longer, but 30-40% more expensive.

### **Specific charger?**

Yes. Deep cycle batteries need an AGM- or GEL-curve charger. NEVER use a traditional SLI charger.
