Great delivery service.Battery is a replacement for a Ryobi battery and it is going great, less than half the price of a Ryobi replacement.

I know little about batteries for lawnmowers, hedge cutters and whipper snipers. When my Ryobi went I was shocked at the price of its replacement. Thank you Battery World for a replacement at a moderate price delivered quickly. Very happy.

Batteries arrived quickly. Met the description and work well. Great price.Happy Customer 🙂
I was doing a search as I needed a new battery and came across Battery Mate. Price was sensible and the service was reasonable. Battery works well and so I am happy to recommend Battery Mate to others.
Ryobi battery are extremely expensive..needed a battery for my pressure washer 40v 4Ah works great .will buy more battery's..thanks again matt
i have a Ryobi 36v top of range cordless mower that I have had for many years.The battery died and a replacement genuine battery is too expensive and apparently no longer available. The battery from Battery Made is good value and works great. Ordered on Tuesday (living in Adelaide) and received Thursday same week on free delivery Amazing service. Highly Recommend
The Ryobi Mower Battery worked well. and I mowed my lawn after charging the battery the very next day. Ill be back to buy another battery when Battery Mate has more Ryobi batteries in stock. Thank you John.
I am very happy with this product. Fits existing Ryobi charger and is a lot more affordable than the branded product.
I have recieved the battery and service was good. It is very difficult to give a proper review after only 2 or 3 charges. Whether it lasts as longs as the OEM product will determine its real value. It works as well as the original at this stage.
