My car battery has been going flat the last couple of weeks, Used the car last Saturday after i charged the battery because it was flat, Didn't use it during the last week but tried to start it today, Flat again, It's now on charge.. When changing the battery is there anything i should be aware of? Reseting anything? Looking online and having problems finding the correct battery which caters for stop/start. Halfords don't seem to have them, neither do a lot of the online suppliers.

The information in these documents might be of help regarding your current battery :-
I've searched the Halfords site using these details "Mazda CX-3 1.5 Automatic Diesel 2017/2018 (67)" (Note: I'm certain it would be the same for a manual model and / or a 2017 17 plate)
and it brings up the Yuasa YBX7005 for £142

Here is the same battery on the Yuasa site :-
https://www.yuasa.co.uk/ybx7005.html
Capacity Ah (20-HR): 65
Capacity at 20-hour Rate (Ah): 65
Cold Cranking Performance (Amps) EN1: 620
The only query I have concerns the battery measurements - it says :-
Length (mm) 232
Width (mm) 173
Height (mm) 225
I think one or more of these measurements might potentially be a problem i.e. too big
You'd need to measure your current battery, or more relevant the battery tray and fixings, to make sure this new one would fit ok.

Thanks for the reply. I was looking at that one in Halfords but it's not available to collect or for delivery. I phoned them and was told they cannot get that battery anymore, It's been discontinued by Yuasa..Looked on Euro Car Parts and they have 4 different batteries, Exide, Bosch, Varta and Lion but they are all lower spec than what is on the car already (amps, CCA Etc) and 3 of them are just shy of £200
Does the spec of a new battery have to be exactly the same as the one thats already on the car or would a battery with higher Amps and cold cranking speed etc be ok?

It may be worth tesing to see if there is a discharge from the battery when you think you have switched everything off. To do this you need anmeter which can read up to 10 amps, disconnect the positive terminal of the battery and join the ammeter terminal between the battery terminal and the positive lead going to the car after making sure that you have set the ammeter correctly i.e. 10 amps. The only discharge you should see is for the alarm which is only a few milliamps. If you see 100 milliamps or more then there is a fault which neds to be investigated.

If a new battery is needed (I changed mine earlier this year) I found our Mazda dealer was the cheapest around!
And a battery of higher Amp/HR would be fine as it means it can supply those amps for that time, it's the load (ie the cars electrical items) that defines how many amps are drawn from the battery.
If you use a meter in the current (amps\milliamps) setting whatever you do don't connect it across the battery (pos to neg) as you could cause damage because you will be short circuiting the battery!

Thanks for the replies, I'll check it first with the meter before splashing out any money on a new one, Thanks again
