MK Battery M22NF SLD A 12V 55Ah AGM Batteries, Pair

This listing supplies two MK Battery M22NF SLD A batteries, each rated at 12 volts and 55 amp-hours. The sealed AGM construction is valve-regulated and maintenance-free; this is a different chemistry and model from the M22NF SLD G gel battery. Verify which version the equipment requires instead of choosing by group size or capacity alone. The pair's system voltage and amp-hour capacity depend on the device's wiring.

Confirm the Battery and Tray

Compare the M22NF SLD A model with the equipment maker's specified battery. Check the number required, case dimensions, tray clearance, terminal style and orientation, cable reach and hold-down arrangement. A battery can have a matching nominal voltage and still be incompatible with the device or charger if its chemistry, terminal layout or dimensions differ.

Charging and Storage

Use the charging profile and voltage settings specified for AGM batteries by the equipment manufacturer. MK describes the M22NF SLD A as suitable for standby and cycle use and lists low self-discharge during storage; it still needs proper charging and handling. Do not replace a gel battery with AGM, or AGM with gel, without confirming compatibility. Follow the device and battery instructions for connecting, charging and storing the pair.

Pair Quantity and Installation Service

The product is sold as two batteries when equipment calls for a pair. Follow the equipment's wiring diagram for series or parallel connections rather than assuming the two labels add directly to system capacity. Optional installation service is labor dispatch and installation only, is non-refundable and may involve a distance-based fee. Check service coverage before selecting it.

Before Ordering

Verify the M22NF SLD A model, pair quantity, per-unit 12V/55Ah rating, AGM chemistry, terminals, tray fit, wiring and charger settings. Select this model only when the device specification calls for AGM batteries.

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.
