Both RYOBI ONE+ 18V and 40V batteries have models with onboard LED fuel gauges, but the available product information does not establish that their light counts, layouts, colors, or flashing patterns are the same. The gauge on a battery is also separate from the lights on a charger: the charger’s LEDs report charge status.

What do the lights on a RYOBI battery mean?

On the cited battery models, an onboard LED fuel gauge is intended to monitor remaining runtime. RYOBI does not provide a universal pattern legend on the product pages for every battery, so a light count or flashing sequence should not be interpreted across models without checking the exact battery’s manual.

ONE+ 18V: PBP005 4Ah lithium battery

RYOBI describes the 18V ONE+ 4Ah lithium battery (PBP005) as having an integrated LED fuel gauge to monitor remaining runtime. The product page does not establish a universal meaning for each illuminated segment or flashing pattern.

40V: 4Ah Lithium High Performance EDGE battery

The 40V 4Ah Lithium High Performance EDGE battery also has an integrated LED fuel gauge described as monitoring remaining runtime. Its product page does not provide a cross-model pattern legend.

Do RYOBI 18V and 40V batteries have the same indicators?

The cited examples share the same stated purpose—monitoring remaining runtime—but the reviewed product information does not establish that the indicators use the same number of LEDs, layout, colors, or blinking patterns. Treat each gauge as specific to its battery model rather than assuming an 18V pattern means the same thing on a 40V battery.

How do I check the charge on a RYOBI 18V battery?

For the cited PBP005, use its onboard LED fuel gauge as a runtime-monitoring indicator. For the meaning of a specific number of lights, color, or flashing sequence, consult the operator’s manual for the exact battery model; the product page does not define those patterns.

What do the lights on a RYOBI charger mean?

Charger LEDs are a separate indicator system from the battery’s onboard gauge. RYOBI says the ONE+ 18V/40V Dual Platform Charger (PCG007) uses its LEDs to show battery charge status. For a particular light sequence or fault state, consult the manual for the charger model rather than applying a battery-gauge interpretation.

PCG007 charging examples

RYOBI’s PCG007 product page gives these charging-time examples: 15 minutes for an 18V ONE+ 4Ah EDGE battery and one hour for a 40V 6Ah battery. These are manufacturer claims for the named batteries and charger, not general times for every capacity or charger. RYOBI also says the charger’s active cooling reduces charge time while extending battery life.

Choosing a replacement battery or charger

  1. Match the platform. Confirm whether the tool requires RYOBI 18V ONE+ or RYOBI 40V; the two battery platforms are not interchangeable.
  2. Verify the model and capacity. Compare the replacement’s model and amp-hour rating with the tool’s requirements.
  3. Check the gauge feature. The cited 18V and 40V examples both include onboard LED fuel gauges, but confirm the feature on the exact replacement model.
  4. Consider a dual-platform charger only if useful. RYOBI lists the PCG007 as compatible with any RYOBI 18V ONE+ or 40V battery. Its charge-status LEDs belong to the charger, not to either battery gauge.

For out-of-warranty battery replacement, RYOBI’s battery and charger support page directs customers to The Home Depot and includes both 18V and 40V battery types.
