NTV/Revere Batteries.....

[Jake]

Just thought I ‘d mention a few sites for anyone
who needs a new battery shortly (like me).....

I normally buy a battery from Wemoto because of
quick delivery times (usually the next day) and have
always used Yuasa batteries because they seem to
hold their charge longer and are pretty reliable.

County Battery Services however, also sell the Yuasa
and a selection of other batteries for the NTV.

As an alternative to the Yuasa however, Motorcycle
Products Ltd also sell the ‘Motobatt’ AGM batteries at
a cheaper price than Wemoto at £44.23.

Motobatt AGM batteries are supposed to have up to
20% more cranking power than normal sealed batteries
and according to the advertising blurb are ‘factory
ready’ straight out of the box. (There’s no messing
about filling them with acid beforehand.) They also have
four posts i.e. 2+ and 2- which can be useful if you have
heated clothing like a heated waistcoat or gloves etc.
Another advantage over normal sealed batteries types
is that they can be left for longer periods without charging.....

Apparently, ‘AGM’ stands for ‘Absorbed Glass Mat’ which
means that:

‘Each plate in the battery is wrapped in a glass wool matting which keeps the plates separated in a cushioned environment. This stops the plates vibrating and causing faults between the plates which result in terminal failure.’

The only drawback is that your battery charger has to
be suitable for charging an AGM Battery, which most
modern chargers are.……

Just an update....I've ordered my Motobatt, AGM Battery
from Wemoto because they've dropped their price from
£54 to £46.23.....

I did phone Motorcyle Products Ltd., to see if they had one in
stock, but the guy who answered the phone didn't know.
He said he'd phone me back, but never did so, which doesn't
exactly inspire confidence.

Are they 'gel' type batteries (ie: able to be used in their side)?

AGM stands for Absorbed Glass Mat and according to
the manufacturers:

‘Each plate in the battery is wrapped in a glass wool matting which keeps the plates separated in a cushioned environment. This stops the plates vibrating and causing faults between the plates which result in terminal failure. This also helps reduce the "mossing effect" that comes from plate sulphating migrating from one plate to another and creating a short. Sulphated lead particles are also unable to float around in the battery and cause shorting between plates as the acid solution is absorbed into the glass matt. Due to these and other advantages on the design, AGM batteries have a much lower discharge rate than wet flooded types.’

So, no…strictly speaking they are not the gel type.

But I’ve found that they give a bit more cranking
power than the Yuasa battery I’ve used before.
The bike usually fires up strightaway even if the
engine is cold. Also, when the headlight is on and
I switch my heated waistcoat on as well, it seems
to warm up a lot more quickly…..

However, on the NTV the bike battery leads will
only connect to the top of the battery (not the side).
Initially, Wemoto sent me the wrong battery terminal
posts (which you have to fit yourself) and the bike
leads were too short to connect to the side of the battery.
When I phoned Wemoto however, they sent me the correct
terminal posts free of charge…..

Although these battery's have four terminals, in practice
on the NTV you can only use two, because the plastic
cover which hold the battery in place on top, covers two
of the terminals.....

But the Motobatt, AGM battery was still cheaper than a Yuasa...
although it is heavier because it contains more lead.

Just an update on the Motobatt AGM battery I've fitted.....
It's leaking.

Just discovered battery acid beneath the battery,
where it sits in place on the bike.....

Don't buy one unless you're prepared to run the same risk.
