Which Deep Cycle Battery do we recommend?

In a nutshell it depends on your application & your budget. All AGM batteries for example are sealed, maintenance free (i.e. no topping up with water) and they self-discharge very slowly in comparison to the older style flooded deep cycle batteries. They are quick to charge too, and the good brands last well.

A "top of the Range" AGM (e.g. the Lifeline range made by Concorde in the USA) is rated at 1,100 Cycles at 50% Depth of Discharge, and comes with a 5 year warranty. The Ultimate brand of AGM batteries (which are made by Haze in China) is rated at around 500 Cycles at 50% DoD and has a 1 year warranty.

For a customer towing a caravan for a few weeks each year the much cheaper Ultimate battery by Haze would be fine, whereas for a solar installation or offshore yachting the Lifeline is a much better choice. If under-bonnet fitting in an engine bay is a requirement then in the AGM range only a Lifeline would suit.

In General we would suggest;

• For AGM Deep Cycle batteries We would ignore the no-name cheapies to avoid a let-down while travelling and look to Remco & Ultimate ranges for good value for money. The Ultimate has terminals to allow engine starting if needed. For pure deep cycle in AGM then the Ritar & Century ranges are similar, and both are well known and proven in Australia. With Ritar the standard fitting in new Jayco models for several years, both are rated at around 800 Cycles at 50% DoD.

• For the very best in AGM take a look at the Optima Yellow Top range (if you need toughness and vibration resistance and can live with low amp-hours), or the Lifeline range if you can't! Lifeline are more expensive but are unbeatable overall - probably the best AGM battery made today.

• For Accessible Deep Cycle batteries both the Trojan and Century ranges are hard to beat. Century is a trusted Australian brand, and the USA-made Trojan's can really take a pounding.

• Both are cheaper than the equivalent quality AGM or Gel, with a wide dealer network & good warranty support. Flooded batteries self discharge more quickly than AGM & GEL however, do not charge up as quickly and need topping up. A good quality Trojan 100Ah is rated at 500 Cycles to 50% Depth of Discharge. Both are good for under-bonnet installations, unlike most AGM & Gel batteries.

• For Gel Deep Cycle batteries we'd go for Sonnenschein or GEL-TECH for Golf & Mobility Scooter applications. Avoid cheap Chinese gel-cells (a term often given to any old sealed battery).

Gel or AGM Deep Cycle Battery?

• If you want a sealed Maintenance Free battery then we would go AGM, unless you are replacing an existing GEL battery. The AGM is more popular in the market, and tolerates normal charging from an Alternator or standard Wet Lead-Acid battery charger.

• However if flattening the battery is likely to happen, e.g. Golf buggies, then a good quality GEL is better. Make sure your charger has a GEL setting or is designed for GEL to avoid over-charging the battery as they need a lower charging voltage than other Lead-Acid batteries.

Fully Sealed or Accessible (Flooded)?

• If you have a battery space with limited access to "top up" the cells, or are fitting the battery inside a vehicle (e.g. under a seat) or in a metal boat then Sealed is the only way to go!

• However if ventilation and access is good, and if you are the type to remember to check the levels in the cells occasionally, then you can get excellent quality flooded lead acid batteries that will take a pounding and last very well for less than the price of an AGM sealed unit.

• Also of course if its going under a vehicle bonnet read the advice in our installation section and don't buy any GEL or an AGM for that purpose without checking its suitable first (many are not).
