The Starmax High-Temperature GEL Deep Cycle AGM Battery is a high-performance deep cycle GEL AGM battery designed for solar power systems, off-grid energy storage, wind power applications, sweepers, golf carts, and light industrial electric vehicles. Built for extreme temperatures (-15°C to 60°C), it features low self-discharge (2–3% per month at 25°C), a 50% DOD cycle life of over 3,000 cycles, and a float service life of 12–15 years. Supports fast charging and comes with CE, UL, ISO, and IEC certifications. Available in a grey body with black cover, it offers 1–3 years warranty depending on application, providing reliable, long-lasting power for industrial and renewable energy applications.
| Specification | Value |
|---|---|
| Model | SHTL12-75 / equivalent HTL12-75 (12V 75Ah) |
| Nominal Voltage | 12 V (6 cells) |
| Nominal Capacity (20-hr) | 75 Ah (20-hour rate @ 21.0 A, 5.4 V) |
| Other capacity ratings | 10-hr: 68 Ah; 5-hr: 59.5 Ah; 1-hr: 45.8 Ah |
| Chemistry / Type | GEL (High-Temperature deep cycle GEL). Note: similar models are offered as AGM/VRLA in some lines — verify exact part before ordering. |
| Design / Float Life @ 25°C | 15 – 20 years (design floating service life for high-temp GEL variant) |
| Cycle life (50% DOD) | ~1,750 cycles (50% Depth of Discharge) for high-temp GEL variant |
| Internal resistance (full charged @25°C) | ≤ 6.5 mΩ |
| Max discharge current (5s) | 450 A (5 s) |
| Recommended charge (standby) | 13.6 – 13.8 V (initial charging current < 17 A) |
| Recommended charge (cycle use) | 14.4 – 14.9 V (initial charging current < 17 A) |
| Self-discharge | ~3% per month @ 25°C |
| Operating temperature (ambient) | Discharge / Charge / Storage: typically −25°C to +60°C (short description on some pages lists −40°C to +60°C capability) |
| Dimensions (L×W×H) (mm) | 260 × 169 × 211 mm (total height 215 mm). Typical DIN75 variants seen in marketplace: ~276–278 × 174–175 × 189–190 mm (varies by maker). |
| Weight | ≈ 25.3 kg (CSPower HTL12-75 spec). Typical 12V-75Ah lead acid/GEL weights range ~21–26 kg depending on construction. |
| Applications | Solar/off-grid energy storage, UPS, telecom, electric sweepers/forklifts, other deep-cycle uses |
| Certifications | CE / UL / ISO / IEC (varies by manufacturer and SKU; check the product page or PDF datasheet) |
| Notes | This table is based primarily on the CSPower HTL12-75 high-temperature GEL datasheet and cross-checked with made-in-china / alibaba 12V-75Ah listings. Confirm exact model code (AGM vs GEL vs LiFePO4) when ordering — Starmax offers multiple 12V75 variants (AGM, LiFePO4, etc.). |
