EBL 2-Pack 9V Rechargeable Lithium-Ion General Purpose Batteries, 600mAh, 2 Pack

I was very leary about an off brand battery. I shouldn't have been. I highly recommend these. For me they last a month in a tens machine I use everyday.

The charger works as expected. Rechargeable batteries provide much longer life than the old alkaline batteries they replaced. The delivery was on schedule.

Nice charging system and it's great to have a backup battery ready to go.

this is a lifesaver!! I'm very glad I purchased, it's perfect for my TENS machine which is used daily- charges relatively quick %26 batyeries last for long during usage.. I HIGHLY RECOMMEND 👍🏻

It is simple to use

powers my truck right up

Very easy to use quick to charge just received it waiting to see how long the charge lasts does not take up too much space easy to use

So far so good. I have only had it about a month, it is used outside and has held up well in this bitter cold weather.

not very good but it will work ok enough. hard to get battery to stay in charger properly due to just loosely sitting in the charger not actually clicking into anything. decent enough though

The EBL batteries that came with the recharger do not fit the EBL recharger. I have a Maximal Power battery that does fit the EBL recharger, but the EBL batteries do not. I also do not like that I cannot plug the recharger into a regular outlet, but must use the USB cord.
