Seem to hold a good charge. No date of manufacture/expiry.

��غ�� Vine Customer Review of Free Product( What's this? )
I have held off reviewing for a while to see how well they hold their charge and so far I have failed to run one down in a golf range finder in ever decreasing temperatures.
I am therefore quite happy and at £2 a battery (at current prices) I think the value is there.

The only thing I don't like is there is no best before date. This makes it impossible to know if they've been recently manufactured or sat on a shelf for 12 months. Naturally batteries lose 2-3% charge over time so no date stamp could be an issue.

This pack of 6 lithium batteries is 3 volts only.

I used that for my smoke alarm systems and torches. It's just a standard 850 They now work well.

But unfortunately, they are disposable. So they can't be recharged.

I use the CR2's for my home alarm sensors and they have fit without issue and powered up well. I've had them in for a couple of weeks without issue and the cost is better than some more well known batteries. I'm hoping they will last for 6 months or more however, I'll find that out next year. So far, so good.

This battery seems to hold it charge quite well as considering a week of heavy use, it still maintained it voltage correctly. Because it is made with lithium, the battery is also high power density making it suitable for application needs a long term power supplied to it.

��غ�� Vine Customer Review of Free Product( What's this? )
These Jsoprtvr batteries seem to be well built and of pretty good quality; at least equal to that of the well-known brand I usually buy. I ordered them to use in an old wireless doorbell button/transmitter that now seems to go through batteries fairly quickly.

To be honest, I haven’t been able to test the batteries fully in the relatively short time I’ve had them. However, I measured the voltage with a multimeter before installing the battery into the doorbell button a few days ago, and I have since pressed the button far more than usual to test for any voltage drop.

The initial voltage was 3.33v and, after 4 days of quite high use, the voltage now is 3.32v - a promising result.

The Jsoprtvr batteries are lithium batteries and, like most other CR2 batteries, are single-use and non-rechargeable. There are quite a few equivalents to the CR2 battery (such as 1CR2, DL-CR2, DLCR2, 5046LC, CR15H270, EL1CR2, KCR2) so, needless to say, you will need to check carefully for compatibility.

I usually pay just over £7 for two CR2 batteries from a leading brand (about £3.50 each), and they really don’t last very long in my old doorbell. The Jsoprtvr batteries seem to be doing very well by comparison and, at the current price (if you’ll please forgive the awful pun) of £12.99 less a £3 ��غ�� discount voucher (=£9.99) for a six-pack, they work out at about half the price.

Even if they don’t last quite as long as my usual batteries (and I have no evidence to suggest they won’t) the Jsoprtvr batteries are clearly a better buy.

Hope this helps a little.
