What You Need to Know About the Clark TM15 Battery?
The Clark TM15 battery is a lead-acid industrial battery designed for forklifts and material handling equipment. Known for its durability and 36-volt, 510-625 Ah capacity, it powers Clark TM15 forklift models. Proper maintenance, including watering and equalization charging, extends its lifespan to 5-7 years. Key features include spill-proof design, rugged construction, and compatibility with fast-charging systems.

How to Properly Maintain Your Clark TM15 Battery?
Maintain TM15 batteries by checking water levels weekly – keep plates submerged in distilled water. Clean terminals monthly with baking soda solution. Perform equalization charges every 10 cycles. Avoid discharging below 20% capacity. Store at 50-80°F with full charge. Use automated watering systems to prevent mineral buildup. Record voltage and specific gravity readings during maintenance.
For optimal performance, implement a tiered maintenance schedule. First-tier daily checks should include visual inspections for cracks or leaks and terminal voltage measurements. Second-tier weekly maintenance requires measuring electrolyte levels across all cells – uneven levels indicate potential charging irregularities. Third-tier monthly tasks involve thorough cleaning of battery trays and torque checks on cable connections (recommended 110-125 in-lbs).
| Maintenance Task | Frequency | Tools Required |
|---|---|---|
| Water refill | Weekly | Distilled water, hydrometer |
| Terminal cleaning | Monthly | Baking soda solution, wire brush |
| Equalization charge | Every 10 cycles | Industrial charger |
What Are the Total Ownership Costs?
Initial purchase: $2,500-$4,000. Annual maintenance: $300-$500 for water, equalization, and cleaning. Replacement every 5-7 years. Electricity costs average $0.15/kWh – $450 yearly for daily charging. Factor in $200/yr for cell replacements. Total 5-year cost: ~$8,000 vs lithium’s $12,000 upfront but lower maintenance. ROI improves with proper watering systems.
Detailed cost analysis reveals hidden expenses many operators overlook. Battery rotation programs add $150-$300 annually but extend service life. Proper battery wash stations prevent acid corrosion damage costing $800-$1,200 in premature replacements. Energy recovery systems can reduce charging costs by 18-22% through regenerative braking integration. Consider these comparative annual costs:
| Cost Category | Lead-Acid | Lithium-Ion |
|---|---|---|
| Energy Consumption | $450 | $380 |
| Water Maintenance | $175 | $0 |
| Cell Replacement | $200 | $50 |
“The TM15’s thick lead plates withstand 1,500+ cycles if maintained properly. Most failures stem from water neglect – I’ve seen batteries last 10 years with automated watering systems. Always prioritize equalization – it prevents cell stratification that kills 30% of industrial batteries prematurely.”

FAQs
- How often should I water my TM15 battery?
- Check weekly – add distilled water when plates are exposed. Never fill above max level indicator. More frequent watering needed in high-temperature environments.
- Can I use regular car battery chargers?
- No – industrial chargers with 36V output and temperature sensors are required. Automotive chargers risk overcharging and plate damage.
- What warranty comes with new TM15 batteries?
- Standard 2-year pro-rata warranty. Extended 5-year options available. Warranty voids if specific gravity drops below 1.225 or plates dry out.
- How to store batteries long-term?
- Fully charge, disconnect terminals, store in 60°F dry area. Perform refresh charges every 3 months. Check water levels monthly during storage.
- Are lithium conversions available for TM15 forklifts?
- Yes – retrofit kits cost $7,000-$10,000. Require charger replacement and BMS installation. Saves 800 lbs weight, but verify truck frame can handle different weight distribution.
