why do ryobi battery chargers fail?

Question

Charger type: Ryobi 12v #1411141. I've purchased several of these and they all eventually stop working within a few weeks or months. I've been told it's because the battery itself is failing or that I left the battery in the charger too long. Does anyone know the real reason? Thanks.

Answer 1

if you have them out in cold they will fail store and charge them in side above 45F

Answer 2

Ryobi is Junk! Get yourself a DeWalt or a Rigid, they'll last you a long time. I've been using my Rigid 14 Volt cordless for 3 years now and never had a problem with it, and its out in my truck whether its 0 or 90 degrees, never affected it.

Answer 3

I have no experience with Ryobi but my Dewalts never fail, and i've never known one to fail. I wish I could help but the only thing I can say is you usually get what you pay for.I have heard great things about Ryobi but this might be their $$ maker due to low prices on the tools.

CHARGING THE BATTERY PACK Battery packs for this tool are shipped in a low charge condition to prevent possible problems. Therefore, you should charge them until the green LED on the front of the charger comes on. NOTE: Batteries will not reach full charge the first time they are charged. Allow several cycles (operation followed by recharging) for them to become fully charged. CHARGING A COOL BATTERY PACK See Figure 3. If battery pack is within normal temperature range, the red LED on charger will come on. NOTE: If the charger does not charge the battery pack under normal circumstances, return both the battery pack and charger to your nearest Ryobi Authorized Service Center for electrical check. n Charge the battery pack only with the charger provided. n Make sure the power supply is normal household voltage, 120 volts, 60 Hz, AC only. n Connect the charger to the power supply. n Place the battery pack in the charger aligning raised rib on the battery pack with the groove in the charger. n Press down on the battery pack to be sure contacts on the battery pack engage properly with contacts in the charger. n Normally the red LED on charger will come on. This indicates the charger is in fast charging mode. n Red LED should remain on for approximately 1 hour then the green LED will come on. Green LED on indicates battery pack is fully charged and charger is in maintenance charge mode. NOTE: The green LED will remain on until the battery pack is removed from the charger or charger is disconnected from the power supply. n If both yellow and green LEDs come on, this indicates a deeply discharged or defective battery pack. Allow the battery pack to remain in the charger for 15 to 30 minutes. When the battery pack reaches normal voltage range, the red LED should come on. If the red LED does not come on after 30 minutes, this may indicate a defective battery pack and should be replaced. n After normal usage, a minimum of 1 hour of charging time is required to fully recharge battery pack. n The battery pack will become slightly warm to the touch while charging. This is normal and does not indicate a problem. n Do not place the charger and battery pack in an area of extreme heat or cold. They will work best at normal room temperature. NOTE: The charger and battery pack should be placed in a location where the temperature is more than 50°F but less than 100°F. n When batteries become fully charged, unplug the charger from power supply and remove the battery pack.
