Lead-acid vs lithium-ion
These are the two chemistries you will choose between. Neither is universally better — the right one depends on your shifts, your charging setup, and your budget.
| Lead-acid | Lithium-ion | |
|---|---|---|
| Upfront cost | Lower | Higher |
| Maintenance | Needs regular watering, equalizing charges, cleaning | Sealed — no watering, minimal upkeep |
| Charging | 8+ hour full charge plus cool-down; opportunity charging shortens life | Fast charging, opportunity charging during breaks |
| Typical lifespan | ~1,500 cycles (about 5 years single-shift with good care) | Longer cycle life, often 2–3x lead-acid |
| Best fit | Single-shift operations with time to charge and water | Multi-shift operations, fast turnaround, limited maintenance labor |
Sizing: voltage and amp-hours
Forklift batteries are specified by voltage and amp-hour (Ah) capacity. Voltage must match the truck — common systems are 24V, 36V, 48V, and 80V. The data plate on the truck or the existing battery tells you what you need.
Amp-hour capacity determines runtime per charge. Bigger is not automatically better: the battery also has to fit the compartment (length, width, height, and weight all matter for counterbalance). Give the dealer your truck make, model, and compartment dimensions and they will size it correctly.
What affects lifespan
- Charging habits. Deep discharges and opportunity charging wear lead-acid batteries faster. Letting a battery sit discharged causes sulfation.
- Watering. Flooded lead-acid cells must stay covered with water. Dry cells die early — this is the most common cause of premature failure.
- Temperature. Heat accelerates aging; extreme cold temporarily reduces capacity.
- Shifts per day. A battery running three shifts cycles three times as fast as one running a single shift.
- Equalizing charges. Periodic controlled overcharges keep lead-acid cells balanced. Skipping them shortens life.
What affects cost
Battery pricing varies with voltage, capacity, chemistry, and market conditions for lead and lithium. Delivery, installation, old-battery removal, and charger upgrades can all factor into the total. Because prices move, the only reliable number is a current quote for your specific truck — which is exactly what our request form is for.
Getting a quote
The most useful thing you can hand a dealer: truck make and model, battery voltage, how many shifts you run, and whether you want new, used, or are open to either. Put that in the quote form and a vetted local dealer will respond with real options and real numbers.
