## Questions & Answers

**Q: are these LR754 batteries?**
A: No. According to google LR754 batteries are thicker and higher voltage. These are size 13 hearing aid batteries...

**Q: Why are 8 2032 batteries £12.71 i.e. more than £1.50 each when 4 batteries are £3.27, so less than a £1 each.  10 Duracell 2032's are also only £7.20.**
A: The quick answer is don't think more means cheaper, work it out per item as you have , also check use by dates, lots of old batteries out there.offered cheaper before they go best deforestation date  rember the old rules, if it sounds to good to be true...it probably isn't. Also you get what you pay for,.....a cheap battery in general, doesn't last long.

**Q: is this the same as a p23ga battery, I use it in my garage too remote**
A: Hi there, I think you will be ok buying these instead of P23GA. The spec is the same and the listing gives P23GA as an alternate so if you have a problem you should be able to return it.  I bought Duracell for my garage remote as well and they were perfect.  With kind regards, Laurie

**Q: How do you install these batteries**
A: I used them in my pinsentry machine for on-line banking.  There's a little screw in the back of the plastic cover which gives you access to the battery compartment.  Just pop the old ones out and the new ones in.

### ⭐⭐⭐⭐⭐ Duracell batteries

They do the Job

### ⭐⭐⭐⭐⭐ Great value Silver Oxide batteries.
*by J***6 on 4 June 2015*

The SR44 is probably one of the commonest button cell battery sizes. These are good value. Ok, the best-before date may be 2017 (2 years from now), but this doesn't mean they'll stop working in 2 years' time- just that they're only guaranteed until then. Silver Oxide batteries are the best choice for watches and cameras, as they give a constant voltage throughout their life. My batteries did not show any signs of bulging, which could have indicated that they were likely to leak. They took 3 days to arrive, which is reasonable.
