The Westco MK sealed AGM (Absorbed Glass Mat) batteries are designed specifically for motorcycle use, incorporating robust construction and high cold cranking Amps (CCA) to ensure excellent starting particularly in cold conditions. Once fully charged they can be left for long periods without discharging or needing recharging.

These are not to be confused with ordinary 'Gel batteries' which have to be charged as often as ordinary lead acid batteries.



They are supplied fully charged so no further charging before use is required or desirable.

All the Westco batteries below are direct replacements for the batteries listed having the same dimensions, terminals etc.

Depending on the battery type some WestCo batteries are labelled SVR or WCP


There are direct replacements listed below for ordinary gel & sealed lead acid batteries, but not for most 'wet' lead acid batteries.

AGM Battery instructions

I cannot ship batteries outside the UK

For bikes with a 6V alternator, a Regulator/Rectifier must be fitted in place of the existing rectifier to prevent overcharging and damage. An original or modern Voltage regulator on a dynamo equipped bike will be OK.

What exactly is an AGM battery?

An AGM (Absorbed Glass Mat) battery is a lead acid battery that is sealed using special pressure valves and is completely maintenance-free. The electrolyte is absorbed in separators consisting of a sponge like mass of matted glass fibres which uses a recombination reaction to prevent the escape of hydrogen and oxygen gases normally lost in a liquid lead-acid battery. They are non-spillable, and therefore can be operated in virtually any position. However, upside-down installation is not recommended. Once fully charged they can be left for long periods without discharging or needing recharging.

If the bike is not to be ridden for months, it is recommended that the fuse is removed. (You do have a fuse don't you)? Some Voltage regulators have a slight discharge to earth which can lower the battery Voltage to damaging levels over several months.

They have a very high discharge current ability ensuring excellant cold starting characteristics, where applicable. AGM Battery instructions.





Be aware: These are also used in fire alarms which have to be changed every two years. If you see Cyclons for sale cheaply they may be over 2 years old.



These lead/acid batteries are totally sealed and hold the acid in gel form soaked into matting making them totally leak proof and able to be mounted in any position.

Each battery is 6V . Two batteries can be connected to provide 6V or 12V, instructions are supplied.

Full Cyclon instructions

These batteries are designed for long term use and can easily last 8/10 years, and they can be left for long periods without charging.
Each battery measures 136 x 51x 75MM so 2 can be fitted inside the battery case below or mounted in place of a std. battery. They are not suitable for bikes with electric starts. (5 1/4" x 2" x 3") App.
Two batteries connected in paralell for 6V have a capacity of 10AH, in series for 12V 5AH, and are suitable for use with dynamo equipped bikes fitted with a solid state Voltage regulator. Alternator bikes need a Zener diode or preferably a solid state Voltage regulator in 6V or 12V
Cyclon cells are supplied charged, no further charging before use is required or desirable. Full Cyclon instructions

One Cyclon cell costs £34.95 + £6.95 P&P CYC05

Two Cyclon cells costs £69.90 + £9.95 P&P CYC05/2

Battery case with one cell CYC01 With the Lucas battery box £63.90 + £10.95 P&P

Battery charger, half amp charge rate for slow charging. Ideal for sealed, gel & all lead/acid batteries. Supplied with permanent connection cable kit allows battery to be charged in position on the motorcycle. BCH14028

Spare leads also not available.





Spare leads for Optimate/Accumate chargers & now obsolete BCH012. BCH0N03 £5.95

These do not fit the battery charger above.




Fitting a fuse is always a good idea, and as AGM batteries have a high discharge current capability, in the event of a dead short without a fuse your harness could become a red hot dripping mess very quickly.

This waterproof fuseholder takes std. car type fuses, so even your local Halfords should have them FUBH04 £3.50 with a 30A fuse, spare fuses 25P
