How much does a Trojan 8 volt battery weigh?
Trojan 8-volt batteries typically weigh between 63-72 pounds (28-33 kg) depending on the specific model. For example, the T-875 model weighs 63 lbs (28 kg), while higher-capacity models like the T-890 reach 69 lbs (31 kg). These flooded lead-acid batteries use GC2 terminal configurations and are designed for deep-cycle applications like golf carts and industrial equipment.

What factors affect Trojan 8V battery weight?
Plate thickness and electrolyte volume primarily determine weight variations. Industrial-grade models like the T-890 use thicker lead plates (+15% vs. T-875) for enhanced cycle life, adding 6 lbs (2.7 kg). Pro Tip: Always verify weight when replacing batteries—heavier units may exceed equipment weight limits.
Trojan’s 8V batteries employ lead-calcium alloy grids that balance durability and weight. The T-875 contains 17.4 liters of electrolyte, while the T-890 holds 19.1 liters—a difference contributing to its 3% higher mass. But why does this matter? In golf carts, improper weight distribution from mismatched batteries can cause uneven tire wear. For instance, a 6-battery cart using T-890s gains 36 lbs total versus T-875s, potentially affecting hill-climbing torque.
| Model | Capacity (Ah) | Weight |
|---|---|---|
| T-875 | 170 | 63 lbs |
| T-890 | 190 | 69 lbs |
How does weight impact battery performance?
Heavier lead-acid batteries generally indicate thicker plates and higher durability. The 72-lb Trojan L16 (8V) model lasts 1,200 cycles at 50% DoD—40% longer than standard units. However, increased mass reduces energy density: 8V batteries average 30-35 Wh/kg versus 150+ Wh/kg in lithium alternatives.
Weight directly affects installation logistics. Six Trojan T-890 batteries total 414 lbs—exceeding some aluminum rack systems’ 400-lb limits. Pro Tip: Use reinforced racks when upgrading battery capacity. Consider this: A 10% weight increase reduces e-vehicle range by 2-3% due to rolling resistance. Always balance capacity gains against mass penalties.

FAQs
Can I lift Trojan 8V batteries alone?
Not recommended—OSHA requires team lifting for items over 50 lbs. Use battery carts for safe transport.
Do heavier batteries last longer?
Generally yes. The 69-lb T-890 lasts 15% longer than the 63-lb T-875 due to thicker lead plates.
How often should I check battery weight?
Weigh annually—5% weight loss indicates electrolyte depletion requiring refill. Never operate below 90% original mass.
