MK Battery M17-12 SLD M 12V 18Ah AGM Batteries, Pair

This listing supplies two MK Battery M17-12 SLD M batteries, each rated at 12 volts and 18 amp-hours. The sealed AGM design is described for deep-cycle use and higher current demands. MK lists up to 550 cycles at 50% depth of discharge; actual service life depends on the equipment, charging routine, temperature and depth of discharge. The pair's total electrical output depends on how the device connects the batteries.

Match Chemistry and Equipment

Confirm the device requires the M17-12 SLD M AGM model and two batteries. Check the case dimensions, tray, terminals and orientation, cable reach and hold-downs before ordering. Similar voltage or capacity does not make this AGM model interchangeable with a gel battery or another M17 variant.

Charging and Use

Use the device manufacturer's approved charging profile for AGM batteries. The sealed valve-regulated construction does not require routine watering, but the charger and battery still need to be compatible. Follow the equipment manual for wiring, polarity, charging and storage, and do not apply gel-battery settings unless the equipment maker specifies them for this model.

Pair Quantity and Installation Service

The product is sold as two batteries for equipment that specifies a pair. Connect them in the equipment's stated series or parallel arrangement; do not infer system capacity by adding label values without checking the wiring. Optional installation service covers labor dispatch and battery installation only, is non-refundable and may carry a distance-based fee. Confirm coverage before selecting it.

Before Ordering

Verify the M17-12 SLD M model, per-unit 12V/18Ah rating, AGM chemistry, pair quantity, terminal fit and charger profile. Use this battery only where the equipment's specification calls for it.

GEL vs. AGM Sealed Batteries

AGM (absorbed glass mat) is a special design glass mat designed to wick the battery electrolyte between the battery plates. AGM batteries contain only enough liquid to keep the mat wet with the electrolyte and if the battery is broken no free liquid is available to leak out.

Gel Cell batteries contain a silica type gel that the battery electrolyte is suspended in, this thick paste like material allows electrons to flow between plates but will not leak from the battery if the case is broken.

More often than not an AGM Batteries are mistakenly identified as a Gel Cell Batteries. Both batteries have similar traits; such as being non spillable, deep cycle, may be mounted in any position, low self discharge, safe for use in limited ventilation areas, and may be transported via Air or Ground safely without special handling.

AGM Batteries outsell Gel Cell by at least a 100 to 1. AGM is preferred when a high burst of amps may be required. In most cases recharge can be accomplished by using a good quality standard battery charger or engine alternator. The life expectancy; measured as cycle life or years remains excellent in most AGM batteries if the batteries are not discharged more than 60% between recharge.

Gel Cell Batteries are typically a bit more costly and do not offer the same power capacity as do the same physical size AGM battery. The Gel Cell excels in slow discharge rates and slightly higher ambient operating temperatures. One big issue with Gel Batteries that must be addressing is the CHARGE PROFILE. Gel Cell Batteries must be recharged correctly or the battery will suffer premature failure. The battery charger being used to recharge the battery(s) must be designed or adjustable for Gel Cell Batteries. If you are using an alternator to recharge a true Gel Cell a special regulator must be installed.

If you are unsure which battery or charger is best for your application, please call or email our tech people for help making the correct selection.
