Product Features
Rechargeable Battery
This 12 volt 21ah Start-Stop battery can be discharged and recharged multiple times. Cycle service life will depend on the depth of discharges. See the Technical Specification Sheet for more details.
Maintenance Free
BatteryGuy Start-Stop batteries do not require any maintenance while in use. Electrolyte levels are calibrated during factory production and do not need to be inspected or topped up
Puncture Resistant Case
Each of the 6 cells within this Start-Stop battery is wrapped in a puncture resistant polyethylene envelope so even if the outercase is pierced no leakage will occur.
Corrosion Resistance
We use Silver plated copper Faston Tabs, copper wire lead connectors, Coperized Silver or Lead stud terminals and Stainless Steel nut and bolt terminals depending on the model
Gas Safety Vents
We know charging equipment or the appliance that the battery powers can malfunction but our one way gas safety vents ensure there is no risk of battery explosion or fire.
Anti Buckle Separators
Internal plate buckling can kill a battery outright or simply reduce its lifespan. Our AGM separators gives the plates extra support to eliminate buckling.
High Energy Density
The way we make our 12 volt 21ah Start-Stop batteries means you get an excellent energy per pound of weight ratio.
Optimized Conductivity
The materials we use inside and out have been specially selected for their optimal electrical conductivity so energy loss inside the battery is minimized.
Detailed description
Power-Sonic PS-AUX50 12 Volt 300 CCA Start-Stop Auxiliary SLA AGM battery. Our Power-Sonic PS-AUX50 is commonly used as back-up support to a vehicles main starter battery in start stop situations or when needed to deliver a constant power supply for the vehicles electrical system.
**NOTE: This is a AGM battery and does not require or have a vent hole to hook up a venting hose for cars with standard lead batteries. If your car does have a venting hose this battery will not work for your application and you need to find a standard lead battery that will accept this hose to avoid possible issues with the operation of your vehicle** NOTE - This does not work with the BMW I3 Vehicle**
Venting Battery Example (Our battery will not replace this type)..
The PS-AUX50 is 100% maintenance free, fully charged and immediately ready for use. The 12V 300A (EN) CCA battery has been designed to deliver exceptional performance for high demanding start-stop vehicles.
AGM (Absorbent Glass Mat) batteries are designed specifically for higher demanding stop-start vehicles that use additional electronic technologies to reduce fuel consumption and CO2 emissions. These technologies include brake regeneration systems and gear shift indicators. Power Sonic Start Stop Auxiliary batteries can handle the increased demand from these fuel saving technologies and are also able to power a wide range of ancillary equipment, even when the engine is idle.

Alerts and Warnings
If your application runs on multiple batteries, make sure to replace all of them at the same time or you will dramatically reduce the lifespan of the new batteries by mixing them with older batteries.
You have to install your replacement batteries in the same original configuration they came out and are required to use your existing hardware and cables to reconnect the replacement batteries when applicable.
It is your responsibility to verify the battery or batteries being ordered match the battery or batteries in your application prior to placing your order. Please check your:
- existing battery dimensions (Length x Width x Height)
- quantity needed to replace all batteries
- voltage and amp hour requirements
Manufacturers may change requirements without notice. BatteryGuy is not responsible for incorrect orders - if you need help, please contact us.
