Fits my old Ryobi 18v system just like the OEM battery. (This is not the OEM battery, but a compatible)
So far so good. Arrived packed well and partially charged. 1.5hr on the charger and the battery is performing well.
I will see how it holds up in the future, but right now it was a good buy.

Only 1 of these 2 batteries will hold a charge.  I suggest that you look for a different source for your 18-volt batteries.  This set is not worth the money.
UPDATE -  Energroup fixed the problem.  The product is well worth the money!

I bought one of these Powerextra battery to replace BL1830 18V 3000mAh 54Wh with with one cordless Makita XLC02ZW 18V Compact Vacuum set  1st November 2014. I'd been testing the vakuum before we left for two-months journey, and it worked Okay. As we came back to Florida 10th February 2015 I tried to ladata battery with Makita DC18RA Charger that I had bought earlier I could not charge the battery. It charges for about 5 seconds and then stops with the flashing red/green error. The battery sold by WONDERSHOP. Could I have a new one??

This battery is a great replacement of the original. Delivery was on time and great warranty. I would purchase another one the next time.

Appears to be a high quality replacement battery.  After fully charging it I used the laptop running on battery only for over 2 hrs, then check the battery to find out it still had 70 percent of the charge.

The replacement battery arrived very quickly, as soon as it was charged overnight it began working perfectly and has continued to do so.

The battery was delivered promptly and was exactly as advertised.  I would not hesitate to buy from them again.  In fact, you can count on it.

Bought two of these to replace the batteries in my TrippLite 1kVA UPS.  It was a perfect replacement and seems to hold a charge better than the original.  Much cheaper than replacing the UPS.

I am using this in a APC Backup RS 1500, and the battery was an exact replacement to the old dead one. I let it charge by it's self for 12 hours before I plugged anything into the unit. Hopefully this last for several years. I will update my review if it fails.

Received the battery earlier than expected. Battery was exact replacement for former unit I was using and which had died in the recent past. The battery already had some charge when it arrived and was easily charged to full after a few hours in the computer and AC connected. Have now used the battery for several weeks, including on a trip/cruise to Hawaii where it was crucial for storing pictures from our digital cameras for our trip home.
