Rechargeable Batteries

Rechargeable lead-acid batteries are the same type used in automobiles. As with your car

battery, how you use this battery has a significant impact on its lifespan. With proper use and

treatment, a lead-acid battery can last for years. Here are some recommendations for getting

the longest life from the internal battery.

General

Usage

Fully charge the battery before using the speaker.

Charge the battery completely after each use.

Storage

For best product longevity, do not store at exceedingly hot (greater than

90 °F / 32 °C) or exceedingly cold (less than 32 °F / 0 °C) temperatures.

It is acceptable to leave your speaker plugged in. This will not overcharge the

battery.

If you leave the battery level low and do not charge it for 6 months, it may

permanently lose capacity.

Repair If the battery fails to charge, contact Alto Professional at altoproaudio.com.

Disposal

Bring the unit to a recycling center or dispose of in accordance with local

ordinances.
