[QUOTE=IanH;501810 I think I would be happier having something that is purpose designed for charging sealed lead acid batteries.[/QUOTE]

Is there such a thing for charging such 'small' Ah batteries. The various 'smart' devices I've looked at have a clause that says not be used for batteries below xAh. Can't remember what x is but it was a figure that suggested to me that these sorts of devices where meant for car batteries and the like.

None of the chargers supplied with these kinds of products are 'smart'. It is rare that they would do any damage as they don't put out much current, and I really wouldn't worry about it putting out 0.1v more than the quoted ideal for a sealed batt. A better charger would obviously give more longevity to the battery, but in most cases the battery will fail due to sitting idle for long periods and sulphating, not because of a slight overcharge.

I have found that my battery hasn't even lasted a year and I have been giving it a charge monthly.

Purchased a new battery and a cnet charger last week and will see how we go.

I wonder would it be "smarter" to run up a box or bag with a non-battery Bravo, a decent Battery and a small trickle charger (the cabinet type)? That way, you could leave it on charge when not in use and go for whatever battery suited you best?

Having lived with the unit a week, I think for some that would be a good option.

For me, it was about 40 difference between battery and non battery version. By the time you bought a battery and sorted out a box to store it in, its probably a fair price for the batt version, especially with the convenience of having it all in the one bag.

But if you have an existing non batt version, an external 7ah sealed lead acid battery or Nmh equiv would work well or bigger if you so desired. Whilst it would be potentially more flexible, allowing you to have a couple of batteries on the go at once, or use direct from a car battery, its only a 2 minute job to swap the battery on the batt version. And if you had a conditioning type charger rather than the standard one, you would always have a visual indication on the state of the battery to know it won't run out mid use as mine did first time I used it. Although you could stick a volt meter across the supplied cigarette lighter plug lead and test the battery in situ.

Just my 2p.

If anyone wants to do their own charger unit, the plug that fits the pump is a "Long DC Power Plug 2.5mm / 5.5mm". In other words, 5.5mm dia barrel with 2.5mm hole. Maplin code is HH63T. Not sure how easy it will be to solder though as internal pins are quite short.

Received my CTEK XS 0.8 charger today. Very pleased. It oozes quality in in its packaging.

Took less than 8 hours to fully charge and the LED display indicated progress and indicated a useable 80% charge probably after 3 hours or so. I took measurements at various points and voltage was in the two charging ranges at all points. Currently in standby mode and voltage sitting at 13.5v, right in the standby voltage range of the battery so I would feel happy keeping it on charge for extended periods of time, unlike a standard transformer that had significantly exceeded the batteries cycle voltage let alone the standby voltage.

The only issue I see is making up a suitable plug. The CTEK cables look too nice to cut for wiring into the 5.5mm plug. I temporarily rigged up the charger by clipping the battery terminals to the cigarette lighter plug. But not a good long term solution.

Hope this helps anyone looking for a unit providing visual indication of charge state and hopefully longer battery life.

Thanks to npm48 for pointing me in the direction of the CTEK unit.

Mmmm.

Having brought my Bravo secondhand without a charger I use the one that came with a Jessops AA battery charger years ago.

It's been doing the job fine for a couple of years now.

Hi Ian,

Glad to read you like your CTEK. On my dads boat we had used Mastervolt but they are expensive pieces of kit and needed to find something more cost effective when I bought my cruiser.

The XS should have a comfort connector, which would allow you to use this http://www.ctek.com/mt/en/chargers/C...20Cig%20Socket

Gives you a female cig socket on one end and the comfort connector to hook up with the charger on the other. It's not a cheap accessory though but does keep everything factory new so to speak rather than chopping wires.

Otherwise I guess you could buy a Cig socket from Maplin and put to eyelets on the other end, join with M6 eyelets that come with charger use two small bolts/nuts.

I was lucky enough to get a good price on a CTEK D250S 12V 20amp 5 Stage Charger that I combined with a CTEK Smartpass for full energy management. The D250S is a DC-DC charger which is quite unsual but gives you a fully optimised 5 step charging profile that runs off your alternator but then optimsies the charging output to multiple battery banks. It can also accept other input sources like solar panels.

After the first season I added an M200 AC-DC 8 step 15A charger which I used to keep my batteries fully maintained and charged in winter. Again the M200 is wired via the Smartpass.

Where did you buy your XS 0.8 from? I will most probably invest in one for the RIB as well, because it should be okay for maintenance charging of the RIB battery too.

Hi

Unfortunately that lighter socket won't work. The comfort plug is the wrong gender. It's designed for powering accessories via the cig lighter when the vehicle etc already has a comfort lead permanently attached to the battery. I'm sure many people may have been caught out by that as its not obvious - thankfully I spotted the little note on the ctek website.

I did however end up buying a comfort indicator lead, an extra 6 from amazon. I feel much better cutting the eyelets off of that than potentially invalidating the 5 year warranty on the accessories supplied with the main unit. Plus I can leave it plugged in and it will tell me state of the battery and whether it needs topping up.

I bought charger for 35 inc from advancedbatterysupplies.co.uk. No reason other than they did free next day delivery and I didn't have to go delving through copious web pages to find delivery charge as with some other sites.

For me, knowing the state of the battery and it always being good to go was well worth the extra of the ctek unit.

I would also like to thank The Rib Shop for their help and no quibble full refund.
