Cheers for that chaps,I've already got a 12volt car battery charger in the shed I'm guessing that would do the trick.?
Plan is to be able to inflate the sib next to the caravan(static) as the car park is 50yards or so away,this would
Solve a problem for me ,where as I can set up everything in one place then pull the trailer,sib and OB over to the car and hitch up
And drive away.
If that make sense..

Yuasa NP7-12, 12V 7Ah lead acid battery NP7-12 . You can get battery and charger for 25 from Amazon.

PeterH Your link (that i can no longer see so was the link added/hijacked by advertising?) to charger mentions gel battery compatibility so should be ok..

I think gel batteries cannot be charged at as high current that a typical car battery charger may charge at. Many gel chargers are basic transformers that charge at very low current and will take much longer to charge than a higher capacity charger designed with gel batteries in mind.

If you've got an air floor v type then getting the floor up to pressure after it's been in the water is crucial. Leave it in the water for a few minutes and then pump it up as the floor will inevitably lose pressure once it's in the cold stuff. The small battery I mentioned above is ideal for this as it's about the size of a bag of sugar. Humping a car battery to the water for this job is much less appealing.

Cheers

I will have a look on amazon for the description given on the YUASA battery and compatible charger....thanks again mate .

The 22aph is 215

I already have a similar jump starter to that linked above which has never been used for its original purpose. I'll see how that performs with my Bravo on my fastroller.

I didn't link to anything... If you got a link on my post then this proves my theory that some advertising is hijacking the post and putting links in. I'm on iPad so its something within the site rather than any malware. This is really dangerous as I said that your charger was ok based on what I thought was your link, but it was some random link so some random product put in by the advertising on this site so people may be making decisions based on randomly promoted products. So I have no idea whether the car charger in your shed is ok - it is unlikely to be unless it has a gel battery mode.

I use the Yuasa 7Ah battery as mentioned above.

Charge it with a low power/maintenance charger and not a regular car battery charger! Although the Yuasa battery is vented and so will not blow up.

This battery will power my Bravo BTP12 for three or four full inflate/deflate cycles on my 2.85m SIB without recharging.
On a larger boat you would be advised to charge it before each use of the boat.

Try ebay item no. 281114665612 or similar for the charger.

I am sure some of you are battery experts while I am not as knowledgeable as I would like.

I am familiar with deep cycle batteries which deliver power for an extended time and starting batteries which deliver high amps for a short duration and must be recharged before the charge gets low for extended life. Are any of the low amp batteries described good for deep discharge service?
