Re: Battery Replacement
Buy a fresh battery, one manufactured for less than six months. Batteries have a stamped date code or a sticker showing the month and year of manufacture, most codes start with the letter indicating the month: A for January, B for February, and so on. The digit denotes the year: 0 for 2000, say. For example, B8 stands for February 2008. You may find batteries with another sticker as well,this sticker shows the date when it was last re-charged.
According to my sources in Canada, Interstate recharges and changes the stickers on the batteries until they are sold. It is the date code molded or the label on the battery case that is to be taken into account, not the latter peel off sticker. Batteries on sale are likely to be old stock.
The last battery I purchased was 13 months old when i got it.
