Power-Sonic PDC-121050: 12V 105Ah AGM Deep Cycle Battery for Reliable Off-Grid Energy

Engineered for Sustained Cycling in Caravans, Marine, and Mobility Applications

The Power-Sonic 12V 105Ah AGM Deep Cycle Battery is purpose-built for applications demanding regular, deep discharges and consistent cycling. Unlike standard starter batteries, the PDC series features oversized negative plates and a specialised paste formulation that delivers true deep cycle performance, providing stable power over extended periods without compromising service life. This makes it an excellent choice for caravan solar systems, marine house banks, mobility scooters, and other off-grid setups where reliability is critical.

Utilising advanced Absorbent Glass Mat (AGM) technology, this battery offers superior performance, maintenance-free operation, and a spill-proof design that allows safe installation in any orientation. The valve-regulated construction ensures no acid leakage, reducing corrosion risks and making it suitable for enclosed spaces and transport. With a rugged ABS case (UL94-HB) and integrated carry handles, the PDC-121050 is built to withstand the vibrations and shocks common in mobile environments.

Key Features

  • True deep cycle design with oversized negative plates and specialised paste for repeated deep discharges
  • AGM technology for high efficiency, low self-discharge, and maintenance-free operation
  • Spill-proof and valve-regulated construction allows flexible mounting in any position
  • High energy density delivers 105Ah capacity in a compact footprint (306 x 168 x 208 mm)
  • Rugged ABS case with impact resistance and integrated carry handles for easy transport
  • Certified for air transport (D.O.T., I.A.T.A., F.A.A., C.A.B.) and U.L. recognised (MH 20845)
  • M6 threaded terminals ensure secure, low-resistance connections for reliable power delivery

Why AGM Deep Cycle Technology Matters

AGM batteries use a fibreglass mat to absorb the electrolyte, immobilising it and enabling efficient gas recombination. This design not only prevents spills but also reduces internal resistance, allowing faster charging and higher discharge rates compared to flooded lead-acid batteries. The Power-Sonic PDC series enhances this with special additives in the paste that improve performance in deep discharge situations, a common challenge in off-grid and cycling applications. With an internal resistance of approximately 5.0 mΩ, this battery supports high surge currents, making it suitable for inverter loads and motor starts.

Applications

This battery is ideal for a wide range of deep cycle uses, including:

  • Caravans and RVs: Powering lights, pumps, and appliances during extended trips
  • Marine: Reliable house bank for trolling motors, electronics, and onboard systems
  • Camping and 4WD: Running fridges, lighting, and charging devices off-grid
  • Mobility Scooters and Electric Bikes: Providing consistent power for daily use
  • Solar Energy Storage: Compatible with 12V solar setups for remote cabins and sheds

Built for Australian Conditions

With an operating temperature range of -20°C to 55°C during discharge and 0°C to 40°C during charge, the PDC-121050 is well-suited to Australia's diverse climates. The robust ABS case and vibration-resistant design ensure durability on corrugated roads and in marine environments. For optimal charging, pair with the Power-Sonic PSC-126000ACX charger to maximise battery life and performance.

Whether you're upgrading your caravan power system or building a reliable off-grid setup, the Power-Sonic 12V 105Ah AGM Deep Cycle Battery delivers the endurance and dependability you need. Order yours today and power your next adventure with confidence.

Beautiful sturdy, cozy chair, BUT…..
Color: White, Color: White
Updated review. I was so excited to get this chair that I jumped the gun and wrote the review prior to spending more time seated. I only have one issue, which is the back bottom of the seat cushion. That’s a big deal. It appears so thick, fluffy and inviting, however, when I sat in it for a couple of hours it completely went flat in the back feeling like I was sitting on a board. I’m 5’4” 180 lbs, which means my feet don’t touch the floor so adding a cushion will elevate me a little more. I’m OK with that but it’s going to ruin aesthetic of the chair which is which is not ok. I do love the idea of this chair. It’s design and the color. I wish the seat cushion had a zipper, which would eliminate my issue. I’d say if you’re someone who has to spend a lot of hours in this chair, you probably won’t like it. I do like the reclining back and the foot rest. It is comfortable to lay back but that doesn’t change the issue in the back bottom of the seat cushion. I absolutely love this chair, I didn’t want to get up. It’s beautiful and cozy. Assembly was easy as I’ve assembled chairs before. I changed the wheels to a double roller blade easy on hard wood floors. I also scotch guarded the entire chair. This chair is sturdy and well made.

just get it and stop second guessing
Color: White, Color: White
I reallllly love this chair. I almost talked myself out of it because of some of the bad reviews here and there but i’m glad i listened to a majority of the good reviews, because this chair is perfect. shipping: it was super fast. it came 5 days earlier than expected. I got it on a Monday when it said it’d be here on Friday packaging: double boxed and bubble wrapped. Didn’t find any dings or scratches on anything. all parts were there including instructions assembly: my boyfriend put it together in 40 minutes. We didn’t have any issues zipping up the back cover like other reviews said and he said it was easy instructions to follow, and easy to put together. size and comfort: it’s bigger than the pictures let on! I’m 5’3 135lbs and feel like I’m sitting on a giant cloud. The comfort is 10/10. I just had a chair with basicslly zero butt cushion which i cannot have while working from home 8+ hrs a day in a chair. Comfort was the most important for me and I finally can’t feel the flat seat under me. I can’t express how comfy it is. Functions: can move the arm rests up and down. adjust the back to tilt all the way back to a sleeping position or fully upright which i didn’t even realize was a function! The only thing with the armrests; if you’re wanting your pet on it (like advertised) when the arm rests is put down there is a big gap that isn’t comfortable for animals (as pictured) so I have to put a blanket or pillow there for my small dog to lay comfortably. I’m obsessed with the fact I can sit cross legged, normally, laying down, sprawled up, or legs up. I have room to sit however I want, and the foot rests helps a ton with feeling even more comfortable. Overall, I’d get this chair 10x over. Not only do I work from home and spend hours in a chair, but I spend additional time playing video games so a good quality chair is very important to me. This has began to help fix my posture and back and neck issues. Get it!!!

If You Sit Weird Like Me… Just Buy This Chair
Color: Galaxy Black
I work from home and spend a lot of time sitting for hobbies like Legos, PC games, and crafts—so a comfortable chair is a must. I LOVE this chair so far. I’ve always struggled to get comfortable in traditional office chairs, and the ability to move around is really important to me. With this one, I can easily cross my legs, use the footrest to stretch out with my knees bent, or just sit normally. I’m 5’4”, so my feet don’t quite touch the ground, but that doesn’t bother me since I’m constantly switching positions anyway. I’ll probably add a small pillow for extra back support and maybe fold a blanket for a bit more seat cushioning. It’s comfortable overall, but after long periods of sitting, you might start to feel it. The black sparkle version is MUCH cuter in person, and I’m so glad I went with it. A lot of reviews say, “don’t think about it, just get it”—and honestly, they’re right. I debated for a couple weeks before buying, and I have zero regrets. Assembly was easier than I expected. I tend to get frustrated putting things together, but this was pretty painless. One tip: check inside the cushioned back piece for the extra headrest part—you’ll need it to attach to the hard back before inserting it into the cushion. Once I figured that out, the rest was simple. The chair is a bit larger than a standard office chair and can feel a little bulky depending on your desk setup, but I actually like the extra space since I move around a lot while sitting. It feels sturdy and well-made. It’s also slightly warmer than a mesh chair, which I personally love because I’m always cold. I am just happy to find a chair that feels comfortable like a recliner and movable like an office chair.

Great chair
Color: Pink
I love this chair! I use it for streaming and working on making jewelry! It’s very comfortable and I love that I can sit different ways in it! I can stream longer than I could in other computer chairs I’ve had! I definitely recommend this if you have to sit for a long time but like to sit in different positions! The instructions were a bit confusing but I did figure it out! I have had to spot clean it a few times because of kids and pets but the material has held up! The back is very comfortable and supportive! I like that I can adjust it! Great chair for the price! It’s held up well and I like that you can adjust the back!

Good office chair for the money
Color: White
It is a good quality chair that is comfortable and aesthetically pleasing. The arms aren't necessarily big enough to hold our cat - but that's because he's fairly large by cat standards. The arm rests moving is definitely nice and provides lots of opportunities to 'setup the chair' in a way that works best for you. The instructions were relatively easy to follow (take your time and think it through to make sure you have everything 'aligned right' at first) and the chair is sturdy and holding up well.
