The battery electrolyte level in a deep cycle battery or rather lead acid battery needs to be checked regularly. This is because a lot of water is lost when gassing takes place during the electrolysis process. As a result, the ratio of water to sulphuric acid drops, negatively affecting the strength of the electrolyte. This also affects the battery capacity and the overall performance. Sometimes, if not checked, the electrolyte level might run very low uncovering the battery plates. The plates then become predisposed to irreversible damage. To ensure optimal performance and prevent damage to your lead acid battery, you need to topped up occasionally with battery water. A battery filler is a very handy tool to effectively get the job done.
A battery water filler is a bottle designed for topping off battery water to batteries without overfilling. It is designed to automatically shutoff when the right fluid level is reached. Although adding water to battery can be performed without using a designated equipment, it is more efficient and effective to use a battery filler bottle. Otherwise, you might spill a lot of water while trying to aim at the small battery vent. In addition, water spills can also make a smooth floor slippery and dangerous to walk on.
Top 5 Best Battery Filler Jugs
Battery Filler Jugs Detailed Reviews
Performance Tool W54274 Battery Filler (2QT) With Auto Shut Off
The Performance Tool W54274 Battery Filler is similar to the LubriMatic filler in the sense that they both have an automatic shutoff nozzle and a 2 quartz capacity. However, this unit is different because it has two openings; one at the top for adding battery water and the other one for attaching the spout. Its spout has a spring-loaded valve that prevents the nozzle from getting stuck after you press it down into the battery cell vent to release water. It is also made of durable injection molded plastic that makes it strong enough to withstand the force when pressed down.
Plews LubriMatic battery filler
Plews 75-030 auto shut off 2 quart capacity plastic battery filler is a good addition to the tools and equipment for the maintenance of deep cycle batteries. It is indeed a very clever way to retire the funnel you use to add water to the golf cart batteries, your car battery or the batteries in the solar shed. Fitted with an automatic shutoff valve, the filler helps prevent overfilling cells or spilling water when refilling batteries hence keeping the battery top and the floor dry. It has a 2 quarts capacity, enough to refill a bunch of batteries before the next replenishment. Its valve tip is a double action fast flow type that helps prevent after drip hence ensuring that you don’t get into contact with the corrosive battery electrolyte. The filler is made of tough polyethylene that makes it safe to use with battery acid.
MightyMax Deep Cycle Battery Water Filler Review
When you are working in a garage, you are likely to touch different automotive fluids. The last thing you want are tools that will degrade on coming into contact with those fluids. The MightyMax Deep Cycle Battery Water Filler is an ideal water filler for use in such an environment. It is designed to be exceptionally resistant to automotive fluids that are likely to come into contact with it during the process of servicing batteries. The filler has a single opening like the LubriMatic filler that is used for adding battery water to it and for attaching the spout. Its spout or nozzle features the double action fast flow valve tip that prevents fluid from dripping after withdrawal from the cell vent.
OTC 4621 Two-Liter Battery Fill Bottle
In case you are looking for a battery filler made of heavy plastic material and looks durable, then you should add the OTC 4621 Two-Liter Battery Filler to your tool kit. It has two openings like the Performance Tool battery filler although it feels sturdier and costs three times more.The fill cap fits tightly without allowing any air incursion, which is very critical for the filler bottle to operate as intended. It also dispenses water quickly and easily and stops exactly when the cell is full to about the lower line.
Stone River Golf Cart Waterfiller
Albeit scoring a high failure rate among buyers, Stone River Battery Filler is a good way to eliminate the mess found with funnels with its drip-free design. It is made of tough polyethylene material to ensure durability and has two openings like the OTC 4621. Although it boasts having an automatic shutoff nozzle, many buyers claim that it fails just after a couple of uses. It also needs a good amount of pressure to push it down into a battery cell opening.
What is a battery filler?
- Checking the strength of the battery electrolyte.
- Checking the battery electrolyte level.
The first procedure involves using a battery hydrometer to measure the specific gravity of the battery electrolyte. The readings are recorded, temperature corrected and then compared against the voltage measured across the terminals of the battery to determine the state of charge and the overall health of a battery. The second procedure involves checking the level of battery electrolyte and topping it off with battery water accordingly to the correct level. It is very important to ensure that you don’t overfill or underfill the battery.
How to use a battery filler in seven simple steps
The following is a simple seven-step procedure for using a battery filler bottle when maintaining your deep cycle batteries.
- Fill the battery water filler with battery water.
Normally, you will come across two types of battery filler bottles; ones with only one opening and those with two. For fillers with only one opening, you will have to remove the spout or nozzle in order to fill the cylinder with water. Then replace the nozzle and torque it tightly to prevent water from spilling. For battery filler jugs with two openings, remove the bottle cap at the top, add battery water, then replace the cap and torque tightly to prevent air incursion.
- Remove the vent cap from the battery cell.
Ensure you are wearing your safety goggles and a pair of latex gloves to avoid corrosion with acid.
- Direct the spout to the battery vent
Stick the nozzle of the battery filler into the battery hole perpendicularly and press it down. Water will flow through up until the level of the electrolyte rises to the tip of the nozzle.
- Refill Battery to right level
You will also hear the water gurgle as it flows into the cell. Assuming that the battery filler has an automatic shutoff, the flow, as well as the gurgling, will stop as soon as the required level of electrolyte is reached.
- Withdraw battery filler and move to the next cell.
Move to the next cell and remember to refill the bottle whenever it runs out of battery water during the exercise.
- Replace battery vent caps
Once complete, replace the battery cell vent caps, wipe the top and drain any remaining water from the filler bottle.
- Store your filler bottle in a safe place.
Rinse the filler bottle and store it safely in your tool storage area.
Always remember to rinse your battery filler with fresh tap water before storing it in your toolbox!
