Nickel Hydride Batteries

　　What are the reasons for Nickel Hydride Batteries damage and what types of batteries are there?

　　1. Five major factors that damage forklift batteries

　　1. Wrong charging operation

　　Charge at the operator’s convenience. A charging plan should be set up when installing the battery system, as different facilities require different types of charging systems. Such as battery replacement, opportunity charging or fast charging.

　　All batteries have a limited number of charge cycles before battery capacity begins to decrease. For most industrial batteries, this is generally around 1,500 charge cycles, which equates to about 5 years of regular use. Setting up a charge schedule for your battery can extend its life, saving a lot of money.

　　2. Wrong hydration process

　　Replenish water before the battery is fully charged. It may overflow and remove some of the sulfuric acid, thereby removing the electrolyte balance specific gravity. This will cause the voltage to go awry and if this process is repeated, the battery will degrade significantly.

　　The correct time to add water is once every 1-3 weeks, depending on many factors: temperature, type of utilization. It is important to set up routine checks to monitor the water level in your Nickel Hydride Batteries.

　　3. Using the wrong charger

　　The charger is too big or too small. This usually damages the battery because chargers are specifically designed to work with batteries of a specific size and capacity.

　　Use outdated technology. Such as mechanical chargers (iron and SCR). These chargers can cause the battery to overheat, consume more water, and increase the temperature of the battery, damaging the battery over time. The cumulative result is a significant reduction in battery life.

　　4. Charging and working temperatures are unreasonable

　　The temperature is too high or too low. The optimal operating temperature for lead-acid batteries is 30 to 90 degrees Fahrenheit. If it is higher or lower than this range, it will have an adverse effect on the battery.

　　The ideal temperature range for charging forklift batteries is usually 50-86 degrees Fahrenheit. If your forklift operates and charges in extreme temperatures, you should work with an applications engineer to design a battery charging system that better meets these needs.

　　5. Too many or too few batteries

　　In a competitive environment, the unit cost per pallet is increasingly important, and having extra batteries is an expensive way to operate. Charging algorithms can be used to handle these needs more efficiently and ensure you have the appropriate number of batteries.

　　2. Types of forklift batteries

　　1. Lead-acid battery

　　Lead-acid batteries have a history of more than 100 years and are widely used as starting power sources for internal combustion engine vehicles.

　　2. Nickel-cadmium battery

　　Nickel-cadmium batteries are second only to lead-acid batteries in their wide application. Their specific energy can reach 55W·h/kg, and their specific power exceeds 190W/kg. They can be charged quickly and have a long cycle life, which is more than twice that of lead-acid batteries. It can reach more than 2,000 times, but the price is 4-5 times that of lead-acid batteries.

　　3. Nickel metal hydride battery

　　Like nickel-cadmium batteries, nickel-metal hydride batteries are also alkaline batteries. Their characteristics are similar to nickel-cadmium batteries. However, nickel-metal hydride batteries do not contain cadmium and copper, and there is no heavy metal pollution problem.

　　4. Sodium-sulfur battery

　　Sodium-sulfur batteries are also generally promising electric vehicle batteries in the near future. Sodium-sulfur batteries mainly suffer from serious corrosion at high temperatures and short battery life. Problems such as performance stability and unsatisfactory use safety.

　　5. Zinc air battery

　　The potential specific energy of zinc-air batteries is around 200w·h/kg. It still has shortcomings such as short life, low specific power, inability to output large current, and difficulty in charging.

　　6. Flywheel battery

　　Flywheel battery is a new concept battery proposed in the 1990s. It breaks through the limitations of chemical batteries and uses physical methods to achieve energy storage.

　　7. Fuel cell

　　A fuel cell is a power generation device that directly converts chemical energy stored in fuel and oxidant into electrical energy through electrode reactions. It does not undergo a heat engine process and is not limited by thermodynamic cycles, so its energy conversion efficiency is high.
