Difference between conventional flooded batteries and VRLA batteries: As you alread learned about what is a VRLA battery, charging, storage, Installation VRLA batteries, this post explains on conventional flooded batteries Vs VRLA batteries.
Conventional Flooded Batteries Vs VRLA Batteries
| Sl no | Conventional flooded batteries | VRLA batteries |
|---|---|---|
| 1 | Constant current charging method is normally used for charging these batteries. | Constant voltage with current limiting method is the recommended for charging these batteries. |
| 2 | As excess of free acid is available. Hence electrolyte stratification takes place. To maintain uniform specific gravity of electrolyte equalizing/extended charging is required. | As there is no stratification of electrolyte, no equalizing charging is required |
| 3 | Frequent topping-up of distilled water and acid is required since equalizing/extended charge method is used which results in loss of water | Under normal recommended operating conditions there will no loss of water. Hence the periodic topping- up is not required if the voltage, current, ripple and regulation are in specified limits. |
| 4 | Post corrosion is observed due to acid mist. | No post corrosions in normal operation since there is no acid mist. |
| 5 | These batteries are needed to be placed only vertically since they required frequent topping-up with distilled water and can lead to spillage’s as free and floating acid is present inside the battery | The batteries can be mounted in any position (normally horizontal position is recommended) since they do not require any periodic topping and are both spill and leak proof. |
VRLA Battery Price
VRLA Battery price ranges from 500 Rs to 5600 Rs depending on the brand, features and quality. Some Examples are given below.
