We have compiled all relevant information to help you decide whether to purchase a replacement compatible battery for your Parks Medical 809, 811L, and 811S Doppler devices. These batteries are 6 volts, 1.2 Ah, and capable of deep cycling. They are rechargeable, which is crucial for this type of application. Additionally, they are non-spillable and non-hazardous, making them safe to handle and suitable for indoor use or for portable equipment. The battery cells are AGM (Absorbent Glass Mat) and VRLA (Valve-Regulated Lead-Acid). You can find more information about the qualities of these types of chemistry below.
When you place your order and receive it, you'll notice that the batteries are almost fully charged. However, you should still fully charge them before using them for the first time. The only exception to this is when the batteries are installed in a device that is always connected to the mains, such as an alarm system, which will handle charging for you.
Charging shouldn't take long—just until the charger indicator light shows that it's ready. If you're unsure, leaving it on overnight is more than sufficient, though it's unlikely you would need to charge it that long. While it may be tempting to use the equipment before it's fully charged, waiting until the batteries are completely charged will help extend their overall lifespan.
