Does the ET650 have a maximum of a 50% DOD before damage is incurred or does it have a different DOD figure. If a chargers advertising blurb states it is 'AGM compliant', but it does not have a separate 14.8v AGM specific charge profile, such as the Rovert charger range which has only 14.4v 'Wet' and 'Gel' settings, then the retailer doesn't know their product. well, the obvious answer is another LA95 (two of them will fit (snugly) under an otherwise unencumbered Ducato front seat). Interestingly I too bought a Yuasa battery from Tayna last week, only mine was the YBX5020 (silver calcium) for use as a replacement starter battery. Mine arrived reading 12.53v and I put it on to charge with the very same CTEK 3.6A charger. I presume it eventually reached 14.4v overnight but it took a long time to get started and the voltage even seemed to dip a little over the first hour or so. After 24hrs off charge it has settled at 12.89v. There are rumours of a high technology version of the ET650 on the horizon that will use EFB technology but still be a Deep Cycler but not sure when it is due.

batteries as they aren’t designed for starting vehicles. To get the amp rating, simply multiply the data-parent="#accordion-3">

Most motorhomes have two different batteries: one that’s used to start the vehicle’s engine and a Allegedly BMW are preparing to do the same. Some BMW Dealers have been replacing failed AGM batteries with a Wet Acid technology version, E nhanced F looded B atteries (EFB), for some years to very good effect. damage may occur, damaging the battery to a point where it can't be recovered by recharging.

However, by using an intelligent smart charger specific to the battery type and technology, you can Hence Yuasa launching their latest Leisure battery, the new Yuasa L36-EFB with best in class performance at 'Budget' money.Because the loosely tied bags can be inflated or deflated to accommodate the changing Fridge contents, there is very little air to be lost when the door is open. Bags fold flat when not required so no space is lost.

When AGM batteries have demonstrated they don't deliver, it's time to think more about EFB which are 100% Motorhome and Caravan compatible. Spirou, You write "In any case, that period is always considered as maximum allowed and is hardly ever seen in MH practice unless you discharge deeply". Note. Many customers severely underestimate the amount of time necessary to charge a flat battery. This results in customers returning batteries saying that they have charged the battery but that it is still not holding charge.

Batteries should be installed ideally within 15 months after manufacture. The voltage should be (worse case higher than 12.25V) ideally higher than 12.4V at the time of installation.

Even the industry revered BS EN 50342 battery test document in it's 'super Deep Discharge test' talks of dropping the battery to no greater than 10.8v, and that is 'destruction testing'. A proper motorhome battery charger won't budge from 13.8v once the Boost timer expires, and does it for a reason.

Been a few reports of Tayna batteries being delivered already degraded, one Poster on here with ET650's took advice from Exide who advised rejection they were that poor. But regardless of the above and whether we are to be believed, AGM technology hasn't delivered and is being ousted by the newer, more tolerant, lower cost EFB wet Acid Technology. Around the year 2005'ish Swift started installing Italian designed Nordelettronica NE143, multi stage chargers that were probably the first efficient, modern battery chargers used by a main stream UK builder. AGM batteries typically require a 14.8v charging rate for maximum performance and life, when almost 50% of all the UK Caravans on the roads have a 13.5v/13.8v charger.

I would strongly advise you don't load the CBE CB516, 16 amp, with 2 x 95Ah batteries if you want it to last.
