Hi,
My motorhome has 2 85 Ah lead/acid batteries that don't seem to hold
much of a charge. They are only 18 months old.
I've read recently that if the voltage is allowed to drop below 10.5
volts the cells can be damaged, I suspect the voltage has been low on
several occassions..
Have I damaged the cells????


I am considering putting in 2 110 Ah batteries.
Do gell batteries suffer the same if discharged too much??
Are there any other type of battery I should consider.

Many thanks
Peter

Take a look at AGM (Absorptive Glass Micro-Fibre) batteries. They are
fully sealed life expectancy of 10 years, designed for deep cycle use
and engine cranking. Very low natural loss so should withstand being
left without charging for months, charge quicker than a Gel battery
cost about the same (110ahr about £110).

It's more important what use the batteries get, as long as your aux' 
battery is a true 'leisure' type (the vehicle battery still needs to 
be a vehicle type battery capable of high cranking currents), semi 
deep cycling is not such a problem - what kills batteries is standing 
and having no cycling at all, this is what used to kill lawn-mower 
batteries when they used to be left sitting in the shed and what can 
still kill a battery when a motorcaravan is laid-up over winter. IOW, 
it's just as easy to kill 110Ah batteries as it is 85Ah batteries...

Hi,
Many thanks for your comments.
I have now ordered a pair of 100Ar AGM batteries, which can even be
mounted on thier side.
These can be safely discharged by 70%, but have a very low discharge
when not on load. Therefore I will diconnect them when we are in
Australia for a couple of months.

These can be safely discharged by 70%, but have a very low discharge
when not on load. Therefore I will diconnect them when we are in
Australia for a couple of months.

Take a look at AGM (Absorptive Glass Micro-Fibre) batteries. They are
fully sealed life expectancy of 10 years, designed for deep cycle use
and engine cranking. Very low natural loss so should withstand being
left without charging for months, charge quicker than a Gel battery
cost about the same (110ahr about £110).

It's more important what use the batteries get, as long as your aux' 
battery is a true 'leisure' type (the vehicle battery still needs to 
be a vehicle type battery capable of high cranking currents), semi 
deep cycling is not such a problem - what kills batteries is standing 
and having no cycling at all, this is what used to kill lawn-mower 
batteries when they used to be left sitting in the shed and what can 
still kill a battery when a motorcaravan is laid-up over winter. IOW, 
it's just as easy to kill 110Ah batteries as it is 85Ah batteries...

Hi,
Many thanks for your comments.
I have now ordered a pair of 100Ar AGM batteries, which can even be
mounted on thier side.
These can be safely discharged by 70%, but have a very low discharge
when not on load. Therefore I will diconnect them when we are in
Australia for a couple of months.

It's more important what use the batteries get, as long as your aux' 
battery is a true 'leisure' type (the vehicle battery still needs to 
be a vehicle type battery capable of high cranking currents), semi 
deep cycling is not such a problem - what kills batteries is standing 
and having no cycling at all, this is what used to kill lawn-mower 
batteries when they used to be left sitting in the shed and what can 
still kill a battery when a motorcaravan is laid-up over winter. IOW, 
it's just as easy to kill 110Ah batteries as it is 85Ah batteries...

Hi,
Many thanks for your comments.
I have now ordered a pair of 100Ar AGM batteries, which can even be
mounted on thier side.
These can be safely discharged by 70%, but have a very low discharge
when not on load. Therefore I will diconnect them when we are in
Australia for a couple of months.

Take a look at AGM (Absorptive Glass Micro-Fibre) batteries. They are
fully sealed life expectancy of 10 years, designed for deep cycle use
and engine cranking. Very low natural loss so should withstand being
left without charging for months, charge quicker than a Gel battery
cost about the same (110ahr about £110).

Hi,
Many thanks for your comments.
I have now ordered a pair of 100Ar AGM batteries, which can even be
mounted on thier side.
These can be safely discharged by 70%, but have a very low discharge
when not on load. Therefore I will diconnect them when we are in
Australia for a couple of months.

Take a look at AGM (Absorptive Glass Micro-Fibre) batteries. They are
fully sealed life expectancy of 10 years, designed for deep cycle use
and engine cranking. Very low natural loss so should withstand being
left without charging for months, charge quicker than a Gel battery
cost about the same (110ahr about £110).

It's more important what use the batteries get, as long as your aux' 
battery is a true 'leisure' type (the vehicle battery still needs to 
be a vehicle type battery capable of high cranking currents), semi 
deep cycling is not such a problem - what kills batteries is standing 
and having no cycling at all, this is what used to kill lawn-mower 
batteries when they used to be left sitting in the shed and what can 
still kill a battery when a motorcaravan is laid-up over winter. IOW, 
it's just as easy to kill 110Ah batteries as it is 85Ah batteries...
