Changing batteries is done infrequently so when it has to be done you can count on MK Battery and Digital Telecom to insure you receive a premium battery manufactured and maintained to consistently provide dependable results.

If your supplier can't tell you the age of the battery they are offering you there isn't a good reason, don't waste your time & money, and don't fall for the Warranty as being good enough explanation.

A battery that lasts 2.5 Years instead of 3.5 Years costs you ~30% in lost time alone, and this doesn't take into consideration the added time & expense for installation and shipping. A cheaper and/or older, mismanaged battery will cost you more in the long run regardless of the Warranty.
