Once a week I will try on answer battery questions I have received over my 25+ years in the battery business.
First question:
How long can you store batteries?
When stored at room temperature (i.e. 70°F/ 21°C), cylindrical alkaline batteries have a shelf life of approx. 5 years and cylindrical carbon last 2 years. Lithium Cylindrical types can be stored from 10 to 15 years. Prolonged storage at elevated temperatures will shorten storage life.

agm or gel batteries –which one is right for you?
AGM or GEL batteries –which battery is right for you?
These two battery constructions are very similar, but they have distinct differences. As a result, one could be a better choice than the other in various applications or uses. Following are the features that make them alike or different:
- Both Gel and AGM are valve regulated lead-acid batteries, therefore, non-spillable.
- Gel and AGM are both maintenance-free designs.
- Gel and AGM are both optimized for deep-cycle operation.
- Both battery constructions are sealed valve regulated lead acid, so unless abused, they will not gas.
- These battery designs are both DOT approved for air travel. This means there is no difficulty to bring aboard an aircraft.
Differences
AGM
- AGM batteries have higher capacity than Gel batteries in equal case sizes.
- AGM has a higher discharge rate than Gel.
- AGM has a higher capacity (more daily range).
GEL
- Gel construction is more temperature stable; therefore, it can operate on a wider
temperature range.
- Because Gel is more temperature stable, in some instances it can deliver a longer cycle-life than
(more cycles equal more daily uses).
- Gel construction allows the lead-acid chemistry to charge more readily than AGM.
- Gel requires a longer initial use period to reach
optimal performance than AGM.

Cordless Phone Batteries
Which batteries work best in your cordless phone at home. NiCD or NiHM batteries? We find NiMH batteries are usually higher capacity and last much longer in your phone. For example, the CPH-515D battery works for many models of phone. Here is a link to see if this battery will work on your your phone: CPH-515D Cordless Phone Battery The batteruy is 2,4 Volts and 750mAh NiMH. Ultra high capacity.
