highest-technology batteries from a company like BatterySpace
DickLawrence (Hudson, MA) 6/29/2012 11:14 AM
Four years ago, I looked at a lot of web sites selling batteries before I decided to go with BatterySpace. I ordered a lead-acid battery, a charger, and some 2-pin connectors for a bicycle lighting setup.BatterySpace is a unique institution in the online merchant world. They don't talk down to their customers, but they understand that purchasing, using, and charging high-tech batteries is a serious business - not just a financial decision, but one with personal safety considerations as well. 21st-century battery technology packs a lot of energy into a small volume, and knowing how to use it correctly is critical.BatterySpace goes out of their way to ensure the customer has access to all important information, through several online forums, with accessible experts available through telephone or email, and with links to other sites, such as "Battery University". The latter is literally a comprehensive online encyclopedia of information, extremely well-organized, and as in-depth as anyone could wish to find in a single online source. The online forums, although not active recently, were extremely well moderated by several of BatterySpace's own experts. They demonstrated extraordinary patience with a large and diverse collection of questioners, and the investment of time to answer all their questions (including many open-ended, not to mention uninformed) was impressive - representing a real expense, in moderators' time, to BatterySpace.With their factories and direct relationships with battery producers, BatterySpace removes at least one, and probably two, layers of middlemen between small customers like myself and the huge factories that make batteries for the world. It is very satisfying to educate myself (with help from Battery University), make informed decisions, and purchase the highest-technology batteries available on the planet from a company like BatterySpace.Four years after my first order with BatterySpace, the original lead-acid battery was dying, after ens
