What Is A Trojan T890 Battery Replacement?
A Trojan T890 battery replacement refers to an 8V deep-cycle lead-acid battery designed for industrial applications like floor scrubbers, lift platforms, and marine equipment. With a capacity of 190Ah, it provides sustained power for heavy-duty cycles. Genuine T890 replacements prioritize durability and compatibility with original systems, though third-party alternatives may offer similar specifications at varying price points.

What are the technical specifications of the Trojan T890?
The Trojan T890 operates at 8V with 190Ah capacity, delivering ~1.52kWh energy. Built as a flooded lead-acid (FLA) battery, it uses thick plates for deep discharges (up to 80% DoD) and withstands 800+ cycles at 50% DoD. Pro Tip: Monitor electrolyte levels monthly—low levels accelerate sulfation, reducing lifespan by 30–40%.
Industrial applications demand rugged construction—T890 batteries feature reinforced casing to resist vibrations in scrubbers and marine environments. For example, a scrubber using two T890s in series (16V system) can operate 8–10 hours daily. Transitionally, while lithium-ion alternatives offer longer lifespans, lead-acid remains cost-effective for moderate-use scenarios.
Which devices commonly use T890 batteries?
T890 batteries power floor scrubbers, electric liftgates, and small marine vessels. Their 8V configuration suits systems requiring intermediate voltage—commonly paired in series for 16V or 24V setups. Pro Tip: When replacing multiple batteries, use the same production batch to minimize voltage imbalances.

Scrubber brands like Tennant and Nobles often integrate T890s due to their torque-friendly discharge curves. Transitionally, lift platforms benefit from their high inrush current tolerance during motor startups. However, golf carts typically prefer 6V batteries (e.g., Trojan T105), making T890s a niche solution for 8V-driven systems.
| Application | Voltage Setup | Typical Runtime |
|---|---|---|
| Scrubber | 16V (2x8V) | 6–8h |
| Lift Platform | 24V (3x8V) | 4–5h |
How does the T890 compare to similar Trojan models?
Unlike the 6V T105 (225Ah) for golf carts, the T890’s 8V design targets specialized industrial equipment. The T875 (8V 170Ah) serves lighter loads but shares similar dimensions, allowing direct swaps in compatible systems. Pro Tip: Opt for T890 over T875 if energy demands exceed 1.3kWh/day.
Trojan’s 8V lineup also includes the Ranger 160, optimized for cyclic marine use. Transitionally, T890s outperform generic FLA batteries with 15–20% higher cycle counts. However, lithium-ion alternatives like Redway’s 8V 200Ah LiFePO4 offer 3x longevity but at 2.5x the upfront cost.
| Model | Voltage | Capacity |
|---|---|---|
| T890 | 8V | 190Ah |
| T875 | 8V | 170Ah |

FAQs
Yes, but requires voltage-compatible LiFePO4 (8.4V max) and a charger adjustment—lead-acid profiles risk undercharging lithium. Confirm BMS integration for over-discharge protection.
How long do Trojan T890 batteries last?
3–5 years with monthly maintenance. In high-vibration environments, secure mounting brackets to prevent casing cracks that reduce lifespan by 40%.
