Okay, so, I’ve got this Tennis Tutor Plus ball machine, right? It’s been great, but the battery started acting up – wouldn’t hold a charge for more than, like, half an hour. Definitely time for an upgrade. I mean, who wants to cut their practice short because of a dying battery?
First thing I did was look around for replacement batteries. These things can be kinda pricey, but I found a good deal on a set of two 12V 7.2Ah batteries. They were labeled as “compatible replacements” for the Tennis Tutor Plus, so I figured they’d work. I made sure I got the ones with F1 terminals, ’cause that’s what the old ones had.
When the new batteries arrived, I grabbed my tools and got ready to get my hands dirty. I unscrewed the panel on the bottom of the machine – that’s where the battery compartment is. Inside, I saw two old batteries all wired up. I took a quick picture with my phone, just to remember how everything was connected – didn’t want to mess that up later.
Then, I carefully disconnected the old batteries, taking note of which wire went where. The red one is positive, the black one is negative, pretty standard stuff, but it is important to get this right. Once the old ones were out, I put the new batteries in their place. They fit perfectly, which was a relief.
Next, I reconnected the wires to the new batteries, following the photo I took earlier. Double-checked everything, made sure the connections were tight and secure, and then screwed the panel back on. It was a simple swap, really. No need to be a rocket scientist for this one.
After the swap, I plugged in the charger and waited. The little LED light on the charger was red at first, which meant it was charging. I left it plugged in overnight – figured it would take a while since the batteries were brand new.
The next morning, I checked the charger, and the light was green! That meant the batteries were fully charged. I was pretty excited to try it out.
So, I took the machine to the court, loaded it up with balls, and started hitting. And let me tell you, what a difference! I played for over two hours, and the machine didn’t even flinch. It kept feeding me balls like a champ, just like when it was new.
Honestly, this battery upgrade was totally worth it. It was a straightforward process, and now I can practice as long as I want without worrying about the battery dying on me. If you’ve got a Tennis Tutor Plus and the battery’s getting weak, don’t hesitate to do this upgrade. You won’t regret it!
