I’ve been using the WP820 for a while now and I really like it, so I’ve decided to invest in a few more. To make sure I don’t wind up with downtime I want to get a couple replacement batteries, but I can’t find any reference to an official/OEM Grandstream battery available on Grandstream’s website.
I found a few websites claiming to sell them, but I’m always a bit suspicious of this when I can’t even find a product SKU for the replacement battery. I see the GMC08 which looks like it’s designed to charge the extra batteries, but no batteries for it to charge. What am I missing?
