This provides several key advantages over standard batteries, they are also 100% sealed, non-gassing and maintenance free (this means your batteries will never leak acid, even if damaged), and they will provide a significantly longer service and cyclic life (up to 2-3x longer than standard batteries).

120 AH batteries

I searched long & hard for new batteries for my mobility scooter without going O/Seas. I use my scooter mainly for taking my German Shepherd dogs out for their exercise. Being disabled, it is the only way I can get sufficient exercise for them. In their prime, & when we can get a suitable surface, I run them at short bursts of 14 KPH and we stay out for 1 to 1.5 hours. The scooter came with 2 x 50 AH batteries & I find I am forever having to charge them up. As they have gotten older I have had to cut down on the time I can spend out with them. I have gone for the 120 AH batteries so that I am not quite so restricted. I would also like to thank you for the speed of delivery all the way from Qld to SA. When the time comes, I will return again for more of the same.

Great support and fast delivery

I rang up Aussie Batteries with a few questions about the battery which they answered for me, and lead to me purchasing it! Very friendly service and the battery turned up in 2 days! It has been fantastic so far and would highly recommend it.

Happy Now!!!!!!

The best thing I can say is that I don't know much about the battery. That means that it is doing it's job very effectively so that I don't have to worry about having power when I need it!!
