After many years of using an AER Mobile or compact amplifier the batteries may not last as long as they once did. You might find that the amp turns off within 20 minutes of use, or sometimes not even power on when when running on batteries.
Are you seeing the red “low battery” quicker or is it staying on when running on mains?
According to AER the average battery life on a charge is around 4 hours of use, and a typical battery has a lifespan of between 4 and 8 years depending on the number of charges / discharges.
The AER compact battery powered range of amplifiers run from Lead Acid Batteries. They’re sealed and fixed into the amplifier and held in place with brackets.
Here at Sickamps, we keep Lead Acid replacement batteries for battery amps of different sizes and shapes on the shelf and can quickly replace worn batteries giving you brand new set usually within a couple of days.
Replacing batteries in your AER mobile amplifier will restore the several hour use enabling you to busk again on streets without the need for mains or electricity.
