Battery care and maintenance

The battery is the power source for your cordless pressure washer, so proper care and maintenance is essential to maximize battery life. Here are some key battery-care tips:

Charge properly

• Only use the manufacturer-approved charger. Incompatible chargers can damage or shorten battery life.
• Avoid overcharging by removing the battery from the charger once fully charged. Overcharging strains the battery cells.
• Don’t leave a battery in a charger for more than 12 hours after a full charge is reached. This reduces charge capacity over time.

Prevent damage

• Store batteries indoors, away from extreme cold or heat. Temperature extremes degrade battery performance and lifespan.
• Never allow terminals to contact metal objects to prevent short-circuiting. Shorts can be dangerous and permanently harm the battery.
• Do not immerse the battery in water. Water can damage protective circuits or corrode connections.
• Handle the battery carefully. Drops, impacts, and abrasions can cause internal cell damage.

Maintain charging capacity

• Only keep the battery stored for short periods, and charge fully before storage longer than a month. Deep discharge from long storage can damage capacity.
• Check charge at least every 3 months when stored for extended periods. Recharge to 60-80% if below that level.
• Consider replacement once the battery holds less than 60-70% original charge capacity. At this degradation, it may no longer power the pressure washer properly or for an adequate duration.

Extend useful life

• Let the battery cool down after heavy use before recharging. Charging when hot strains the battery.
• Avoid deeply draining batteries with regular partial recharges instead. Deep discharges wear out cells faster.
• Don’t expose the battery pack to direct sunlight for extended periods of time. Help regulate temperature.

Disposal

• Dispose of old batteries at approved recycling centers. Do not trash. Batteries can contain hazardous materials requiring special disposal.
• Tape over terminals before disposal to prevent short-circuit fire risks. Prevent contact with metal objects during transport for disposal.

Following these battery care guidelines along with the maintenance schedule will maximize battery lifespan and usefulness. Replace the battery when charge capacity drops substantially.
