Does anyone know if there is a sealed deep cycle type battery that is safe to charge in the rear of a wagon without having to box and vent the battery to the exterior. We are replacing a Thumper that has carked it and would prefer to place a 'conventional' battery in the rear due to lack of room under the bonnet - after reading recent posts we are concerned over the gas produced whilst charging. An advice greatly appreciated.

Basically you can use any AGM (ie Absorbed Glass Mat) and, i think, caclium battery.
Look up:
Optima Yellow top - it has a relatively small capacity of about 55ah at the 20hr rate and expensive but then again it does accept a fast charge (it has sucked up to 40 amps/hr out of my recharger) unlike lead acid deep cycle batteries which can only be charged at around 8 amps or 1/10th of the RC.
Also try the Oddyssey battery series, the Exide Extreme etc. It is a valuable marketing tool of these batteries that they are sealed and can be used in internal spaces. The exide and optima can even be used on their sides. There are more of these batteries coming out all the time.
A company called Powercell is now also producing AGM batteries. If you're in or near brissy ring Leisure Marine at (07) 3245 5111 or maybe your most local chandlrey. Don't know what these batteries are like but they sell a 100amp hour unit at the 20 hour rate for $300 and weighing 34Kg and dimensions 415mm x 173mm x 225. But they have a range from 18AH to 200AH.
There is another fax contact number on this flyer i have for these batteries which is for the company PowerDive at Fax (07) 3348 9929.

Paul, I have an Exide Extreme and it is not a sealed battery. I wouldn't recommend putting this anywhere other than the engine bay.

oops, i meant exide orbital, not extreme as Mikeys accurately pointed out.
But i think everyone is making sealed AGM batteries these days - Trojan have a series as
well, and that company is legendary for their wet lead acid batteries.
Just cruise the internet for sites, all the online shops that sell solar stuff always sell a selection of deep cycle batteries

When we want luxury, we take our 21ft van away, which has 3, 115ah deep cycle batteries under the lounge
seat ( I havent' fallen thru yet ) with the battery charger beside them. If you want more info, give Alan or Dave a call at
Richmond Caravans 45-776553 as they are the agents for Compass and will give you an idea on cost etc.

Moggs.
The danger from hydrogen is low with any battery provided you charge it at the correct rate. the normal lead acid will produce very little hydrogen if the voltage regulator on your alternator is set at the factory voltage. The problem arises when people try to fast charge a battery, even a sealed battery will vent hydrogen if over charged, some modern units have mechanisms in them to store and re use the hydrogen but they still canot handle over charging, Eric.
