1. Buy and use the right battery type - different battery types have different applications
2. Buy and use the right battery size - consider the current load
3. If used in a closed space as back-up power supply - provide proper ventilation

Test, test and retest your application for the batteries under ALL expected environmental conditions and loads. This helps you supply an accurately sized battery for the application. Matching the charger to not only the battery but the mode of operation the charger /battery combo will encounter is critical. For instance, will the charger be expected to help support the load as well as charge the battery? That's a different profile on the charger required. Too many folks think lead-acid batteries can be treated like car batteries or flashlight batteries in a design. You'll also need reliable, proven battery "fuel" gauges and instrumentation to get the most life out of the battery for either you or your client. Temperature should be taken into effect and appropriate measures designed into the system. The more you know about your application/load for the battery in question, the better off you will be.

My advice would be to read a little on what different suppliers are offering, but more importantly, compare information with the different suppliers such as lead types, quality, thicknesses and battery chargers supplied what type, brand and charging characteristics they have. Also mention what forklift you have, what you use it for, where you use it and what type of tires you have, in addition to how many hours you need to use it for.
