## FAQs

### Why choose between flooded and sealed batteries?

When choosing between flooded and sealed batteries, it is important to consider the differences. Flooded batteries contain a liquid electrolyte that can spill if the battery breaks, while sealed batteries hold only enough liquid to allow the electrolytes to flow. Sealed batteries are known as maintenance-free batteries, as they do not require regular maintenance and are less prone to leakage.
1. Flooded Batteries: Flooded batteries contain a liquid electrolyte that can spill if the battery breaks. These batteries require regular maintenance, such as checking and topping up the electrolyte levels. They are typically more affordable upfront but may require more attention and care in terms of maintenance.
2. Sealed Batteries: Sealed batteries, also known as maintenance-free batteries, hold only enough liquid electrolyte to allow the electrolytes to flow. They are designed to be maintenance-free and do not require regular electrolyte checks or top-ups. Sealed batteries are less prone to leakage and are generally more convenient to use.
3. Considerations: The choice between flooded and sealed batteries depends on factors such as the application, budget, and maintenance preferences. Flooded batteries may be suitable for applications where cost is a significant factor and regular maintenance can be managed. Sealed batteries, on the other hand, offer convenience and peace of mind with their maintenance-free operation.
