ORBITRON Battery Restore PRO 1L | Reactivation Fluid for Refillable Lead-Acid Batteries
Make topping up the next step in battery maintenance.
When battery fluid falls, top it up with purified water.
Turn that familiar task into an opportunity to consider the battery's overall condition.
ORBITRON Battery Restore PRO is a reactivation fluid developed for refillable, open-type lead-acid batteries.
It combines high-purity purified water with Asai germanium formulated specifically for lead-acid batteries (water-soluble organic germanium).
Add only the amount required to cells with low fluid levels, up to the specified UPPER LEVEL, just as with purified battery water.
No dilution or mixing is required.
Before replacing a battery, there is another step to consider.
Fluid levels in refillable, open-type lead-acid batteries may fall with operating conditions and time in use.
Normally, the missing amount is replaced with purified battery water.
Battery Restore PRO focuses on that topping-up moment.
Rather than simply restoring fluid volume, routine topping up can become an opportunity for battery maintenance.
Check the battery's condition and maintain it appropriately before immediately deciding to replace it.
Battery Restore PRO offers that option.
Features of Battery Restore PRO
Asai germanium formulated for lead-acid batteries
Uses Asai germanium (water-soluble organic germanium) prepared specifically for lead-acid battery applications.
High-purity purified water base
The base fluid is high-purity purified water.
The product is designed to be added directly, in the required amount, to compatible refillable, open-type lead-acid batteries with low fluid levels.
Topping up and maintenance in one task
Use Battery Restore PRO at the point when you would normally add purified battery water.
Restoring the fluid level to the appropriate range and considering battery-condition maintenance can be done together.
No dilution or blending
Do not mix with water or other liquids.
Leave the existing battery fluid in place and add only the amount lost through a drop in fluid level.
A 1 L bottle: use only what is needed
This product is not intended to have the entire 1 L poured into one battery.
Use the amount required for the battery's size and current fluid-level shortfall.
Who is it for?
For users of refillable, open-type lead-acid batteries who wish to maintain them appropriately and check their condition before deciding on replacement.
Applications include passenger cars, trucks, commercial vehicles, agricultural machinery and construction machinery using compatible open-type lead-acid batteries.
For businesses managing multiple vehicles or machines, the burden includes not only battery purchase costs but also replacement work, disposal and vehicle or equipment downtime.
Battery Restore PRO turns routine topping up into an opportunity to review battery maintenance.
Voltage changes recorded in a verification test
On June 19, 2026, a verification test was performed on large 130F51 lead-acid batteries scheduled for disposal.
The following voltage changes were recorded in two batteries treated with the standard formulation corresponding to the current ORBITRON Battery Restore PRO.
| Unit | Voltage before use | After topping up and 20 minutes of rapid charging |
|---|---|---|
| No. 1 | 1.93 V | 11.87 V |
| No. 2 | 2.35 V | 11.87 V |
Both batteries had been judged unusable and scheduled for disposal.
The test record describes the electrolyte specific gravity as “nearly zero,” with fluid levels low enough for the plates to begin showing. After treatment, the batteries were rapid-charged for 20 minutes and the voltages above were recorded.
About the verification test
These are actual measurements for specific batteries under specific test conditions.
They do not guarantee similar voltage changes or performance recovery for every battery.
Results vary with battery age, internal condition, deterioration, charge state and operating environment.
The same experiment also tested a special formulation containing dilute sulfuric acid. Its formulation differs from the commercially sold Battery Restore PRO, so those results are not included in this product's verification results.
Read the test and application report online
The test conditions, voltage measurements, evaluation limitations and role in routine topping-up maintenance are presented as text and tables, without requiring you to open a PDF.
The commercial-product evaluation covers only No. 1 and No. 2, which used the standard formulation. No. 3 and No. 4, treated with a non-commercial special formulation containing dilute sulfuric acid, are excluded.
The recorded outcome is the voltage change after topping up with the standard formulation and rapid charging for 20 minutes. The test does not guarantee new-battery-equivalent performance, capacity, starting performance or long-term durability.
Routine use involves adding only the missing amount when fluid levels fall and maintaining the battery while checking its condition. The report distinguishes the extreme low-voltage test from ordinary maintenance use.

How to use
- Stop the engine.
- Remove the battery filler caps.
- Check the current fluid level in each cell.
- Do not drain the existing fluid. Add Battery Restore PRO only to cells whose fluid level has fallen.
- As with purified battery water, add the amount needed to reach the UPPER LEVEL.
- Confirm that the UPPER LEVEL has not been exceeded and securely close the filler caps.
- Use the vehicle normally after topping up, or charge it with a battery charger as necessary.
Several charge-discharge cycles may be needed to reach the product's intended performance.
Important: never drain the battery fluid
Battery Restore PRO is not intended to replace all the existing liquid inside the battery.
Never drain the existing battery fluid.
Draining it and filling the battery with this product alone may prevent the battery from operating normally.
Leave the existing fluid in place and add only the missing amount.
Always observe the UPPER LEVEL
More Battery Restore PRO is not necessarily better.
Always keep each cell between the LOWER LEVEL and UPPER LEVEL marks.
Do not add product to cells already at the UPPER LEVEL.
There is no need to use the whole 1 L bottle at once.
Use only the necessary amount.
Check before purchasing
This product is exclusively for refillable, open-type lead-acid batteries.
It cannot be used with every battery.
Do not use it with sealed batteries such as MF, AGM, EFB or gel types.
Do not use it in batteries that are not designed for fluid-level management through removable filler caps.
If you are unsure of compatibility, check the battery markings or instruction manual.
Results depend on battery condition
Battery Restore PRO does not repair physically damaged batteries.
An adequate effect may not be obtained in severely deteriorated batteries or those with internal damage or short circuits.
Results also vary with time in use, temperature, operating environment and charge state.
Precautions
If the product gets on skin or clothing, rinse thoroughly with water.
If it gets into the eyes, flush with plenty of water and consult a doctor if any abnormality is felt.
Close the cap securely after use. Store away from direct sunlight, high temperatures and high humidity.
Keep out of reach of young children.
Maintain, rather than simply replace.
Batteries are consumable items.
However, rather than applying “replace immediately when weak” to every battery, there is also the approach of first checking its condition and performing appropriate maintenance.
With large batteries or multiple vehicles and machines, costs include replacement work, disposal and management as well as the battery itself.
Before you decide to replace.
Battery Restore PRO offers a maintenance option for refillable, open-type lead-acid batteries.

Frequently asked questions
Can it be used in MF batteries?
No. This product is exclusively for open-type lead-acid batteries designed for fluid-level management through removable filler caps.
Should all 1 L be added to one battery?
No. Check the current level and add only the missing amount, up to the UPPER LEVEL.
Should I drain the existing fluid first?
Never drain it. Removing the existing battery fluid and adding this product alone may prevent normal operation.
How does it differ from ordinary purified battery water?
Battery Restore PRO is a reactivation fluid for open-type lead-acid batteries. Its high-purity purified-water base contains Asai germanium specifically formulated for lead-acid batteries (water-soluble organic germanium).
How soon will a change occur?
This depends on the battery's condition and operating environment. Several charge-discharge cycles may be needed to reach the product's intended performance.
Can a completely unusable battery always be reused?
No guarantee can be given. Physical faults such as internal damage or short circuits may prevent an adequate effect.
