Amazon Basics AAA High-Capacity Rechargeable Batteries 850mAh (16-Pack) Pre-charged

There are far better deals than that going for AAA's if you scroll down to the bottom of the page that your deal is on there are 16 oohhee batteries with a capacity of 1100 mAh for £9.99 I have used these and they are as good as many of the other AAA's I have tried.So a higher capacity for a cheaper price.It's a limited time deal so you'd have to be quick.As for chargers I purchased this one today -EBL LCD Universal Battery Charger - 8 Bay AA AAA C D Battery Charger for Rechargeable Batteries Ni-MH AA AAA C D Batteries with 2A USB Port, Type C Input, Fast AA AAA Battery Charger(9008) - for £12.74.I have used a few different makes of these the only thing about these is when they get worn ,the batteries pop out out of the slots this takes along time though. I found a better charger for a difference of £2.75 more,I have edited post to reflect this.
