Excellent. Thank youLithium battery
I'm very happy with my order and the time of delivery will recommend to others. about my time using onebuyBrought a fan back to life!!
Once tracked down this type of battery to onbuy, it was a doddle. Price was excellent, delivery brilliant and my portable fan has a new life. The old battery wouldn't charge up any more(5 years old) so 2 batteries for about 6 quid is a bargain in anyone's book. Well done onbuy(and me)...Batteries
Fast delivery no issuesSuper

Have not used yet, but look ok and arrived on time. More words required so typed more words to fill up.Rechargeable batteries
I brought the wrong size it was for my portable fan so I had to send them back to the sellerRechargeable
The price was goodGreat.
Work every bit as well as other ones I’ve bought at four times the price. Not sure how long they will last but the more expensive ones didn’t last more than three months so it really doesn’t matter! So far I’m seriously impressed. Even came in little plastic cases. Nice touch.Used every day for vape.
Perfect for what l needed
Needed to replace the battery in my solar garden lights. Much better than the original batteries. Would highly recommend them.Very good and reliable seller
Product was dispatched within time and the arrival date was completed as expected. The batteries were not great quality and as expected for purpose but the sellers support was highly admirable and a resolution offered.
