Lead Acid Batteries / Forklift Battery

Triathlon® Battery Solutions supplies flooded lead acid batteries for use in forklift trucks, pallet trucks, access platforms and other electric powered vehicles. We offer both British standard batteries (PZB) and DIN standard batteries (PZS), many of which are available for next day delivery. Our industrial forklift battery cells can be supplied on their own or they can be built in to a tank – which ever you prefer. We guarantee to provide the highest quality cells at very competitive prices. All our traction forklift batteries are:


  • Powered by exceptionally high quality cells.
  • Built by a highly skilled and experienced Battery Technician.
  • Built in a tank which is polyethylene coated to eliminate the risk of the battery shorting out and to maximise impact resistance and durability.
  • Made using the highest quality components.
  • Provided with a drain tube for removing water from the tank.


Maximise the lifespan of your forklift battery

To ensure you receive the best value for money Triathlon® offers a variety of optional extras which can be fitted to your forklift battery during the build process. These optional extras will help maximise the lifespan of your flooded lead acid forklift battery:


In order to ensure your battery continues to perform at optimum levels, and its life expectancy is maximised, it is essential that it is maintained correctly. One key element of this maintenance is ensuring that the battery has the correct levels of electrolyte at all times and as such it is important to ‘top up’ the cells after each full charge cycle. If cells are not topped up after charging, the tops of the plates may become exposed to air which will result in an instant loss of capacity. If this is the case the damage could be irreversible. The acid in the battery will also become more concentrated and this could cause further damage and ultimately affect the lifespan of the battery.

You should also be careful not to put too much water in the cells as this can cause electrolyte to boil over and spill out when the battery is next put on charge. If this happens acid could leak from the battery creating health and safety issues, possibly even injury and potentially damaging equipment. Overall the battery’s capacity will be affected which could lead to shorter run times and increased downtime.

An automatic battery watering system would eliminate all risks and problems as it makes the topping up process very quick and easy. You just need to connect the system to your deionized water supply and the electrolyte levels will be topped up to the correct levels in no time.

The benefits of using an Automatic Watering System include:

Time Savings
There is very little requirement for operator input and no need to remove caps by hand or water cells manually. In fact, as the entire process usually takes just a couple of minutes, it means you or your engineers can spend more time working on other things.

Cost Savings
If you’re saving time then you must be saving money!

Enhanced Safety
There is no risk of operators being injured by battery acid as they do not need to touch the battery during this process.

Increased Precision
Automatic watering systems ensure that electrolyte is reliably maintained at accurate levels so there is no risk of over-filling.


All flooded lead acid batteries (PZB and PZS) are susceptible to acid stratification which occurs during the charging process. Air mixing systems circulate electrolyte within the cells to prevent this from happening. Fitting an air mixing system to your battery not only prevents acid stratification, it also:

  • Reduces charging time and increases charging efficiency.
  • Reduces energy and water consumption, thereby reducing costs.
  • Extends battery life.
  • Decreases battery downtime


In order to maximise the lifespan of your battery it is essential that it’s electrolyte levels are maintained correctly. Installing a Water Level Monitor can make this process much easier as it will advise you when the battery needs to be topped up. The Water Level Monitor is fitted with an LED which lights up in green if the electrolyte levels are ok. When the battery needs topping up the LED will turn red thereby drawing your attention to the fact that action needs to be taken. Fitting a Water Level Monitor can save time and money by ensuring batteries are only topped up when necessary.


Battery monitoring systems are a great asset when it comes to the maintenance of your batteries. They continuously monitor each cell within the battery and provide you with essential information such as when:

  • Cells need to be topped up.
  • The battery needs to be charged.
  • The overall temperature of the battery exceeds a certain level.

The battery monitoring system communicates this information via coloured LEDs. This means that users can do a simple visual check of the battery and quickly determine whether it needs any attention. By reacting to the information provided by the Battery Monitoring System, battery life can be maximised and downtime can be kept to a minimum.
If required Triathlon® can also add your branding to batteries and provide technical training for your staff.
By choosing a forklift battery from Triathlon® you can be confident you will receive an exceptional product which has been built using the highest quality cells and components.


Traction batteries can also be used for Off-Grid installations. If you require any further information about using traction batteries in off-grid applications, please give us a call for some friendly advice on 0800 015 6979.
