Review: Magic, Far better than the older rechargable batteries. Bought Dec 24. - My old NiCad batteries are failing, yes more expensive but last a lot longer without recharging. Money Money It's a poor mans world. Wife buys boxes of batteries, LOL. Some items do not like NiCad batteries, tried them in these items & Magic, Test meter I use all the time, never had to recharge so far after a year. I will be buying more LI batteries, including for my home made solar system. Well there appears to be problems with 3 batteries, 1 in mouse & suddenly died, then tried another & nothing, tried charhing a spare & will not charge. Having read about other makes, there appears to be problems, wonder if they are using the same manufacturer? Even EBL & others, have had faults, batteries burning, not charging, ETC. EBL recommended using a USB charger which worked. On top of this suspect my "Family have been using my batteries & not knowing they are rechargeable bin them. So will be putting the rechargeable batteries in a secure place in future. Will update later.

The batteries work well and last long, they are good value for money

### ⭐ Avoid, worthless rubbish.
*by W***Y on 5 January 2026*

They look good, with a nice charger, but as for reliability they're useless, charged them up and went totally flat in a week without being used, not what li-ion batteries should do.
